    3.0.0
    
    See Also:
    ComponentDefinition.getTextAs(), isChildAllowedInTextAs()
  - isChildAllowedInTextAs
```
public boolean isChildAllowedInTextAs()
```
    Returns if a child is allowed in the text-as area. It is meaningful only if getTextAs() is not null. If true, the text enclosed within the element is considered as text only if there is no other XML element.
    For example, <div> in the following example won't be considered as text. Rather, a div component will be created.
```
<a>
  <div>...</div>
</a>
```
    Default: the same as ComponentDefinition.isChildAllowedInTextAs().
    Since:

    3.5.0
  - getReplaceableText
```
public String getReplaceableText()
```
    Returns the replaceable text, nor null if it cannot be replaced with a text.
    By replaceable text we mean the component can be replaced by a text (a.k.a., string). ZK uses it to optimize the output by generating some content directly.
    The replaceable text must be a string consisting of whitespaces only.

  - getFulfill
```
public String getFulfill()
```
    Returns the fulfill condition that controls when to create the child components, or null if the child components are created at the time when the page is loaded.
    Default: null.
    There are several forms:
    "eventName", "targetId.evetName", "id1/id2.evetName", and "${elExpr}.eventName".
    Since 3.0.2, you can specify a list of fulfill conditions by separating them with comma. For example:
    "id1.event1, id2/id3.event2"
    If not null, the child components specified in getChildren() are created, when the event specified in the fulfill condition is received at the first time.
    It is the value specified in the fulfill attribute.
    
    Since:
    
    2.4.0
  - setFulfill
```
public void setFulfill(String fulfill)
```
    Sets the fulfill condition that controls when to create the child components.
    If not null, the child components specified in getChildren() are created, when the event specified in the fulfill condition is received at the first time.
    
    Parameters:
    fulfill - the fulfill condition. There are several forms:
    "eventName", "targetId.evetName", "id1/id2.evetName", and "${elExpr}.eventName".
    Since 3.0.2, you can specify a list of fulfill conditions by separating them with comma. For example:
    "id1.event1, id2/id3.event2"
    Since 3.5.0, you can specify the URI to fulfill with. For example:
    "id1.event1=/my/super.zul".

  - resolveComposer
```
public Composer resolveComposer(Page page,
                       Component comp)
```
    Returns the composer for this info, or null if not available.
    
    Parameters:
    comp - the component used as the self variable to resolve EL expressions, if any. Notice that UI engine uses the parent component for this argument. If comp is null, the page is used as the parent component. If comp is not null, it is used as the self variable.
    Since:
    
    3.5.0
    
    See Also:
    getApply()
  - getApply
```
public String getApply()
```
    Returns the apply attribute that is a list of Composer class names or EL expressions returning classes, class names or composer instances, or null if no apply attribute.
    
    Since:

    See Also:
    resolveComposer(org.zkoss.zk.ui.Page, org.zkoss.zk.ui.Component)
  - setApply
```
public void setApply(String apply)
```
    Sets the apply attribute that is is a list of Composer class or EL expressions returning classes, class names or composer instances.
    
    Parameters:
    apply - the attribute this is a list of Composer class or EL expressions El expressions are allowed, but self means the parent, if available; or page, if no parent at all. (Note: the component is not created yet when the apply attribute is evaluated).
    Since:
    
    3.0.0
  - getForward
```
public String getForward()
```
    Returns the forward condition that controls how to forward an event, that is received by the component created by this info, to another component.
    Default: null.
    If not null, when the component created by this info receives the event specified in the forward condition, it will forward it to the target component, which is also specified in the forward condition.
    
    Since:
    
    3.0.0
    
    See Also:
    setForward(java.lang.String)
  - setForward
```
public void setForward(String forward)
```
    Sets the forward condition that controls when to forward an event receiving by this component to another component.
    The basic format:
    onEvent1=id1/id2.onEvent2
    It means when onEvent1 is received, onEvent2 will be posted to the component with the specified path (id1/id2).
    If onEvent1 is omitted, it is assumed to be onClick (and the equal sign need not to be specified. If the path is omitted, it is assumed to be the space owner Component.getSpaceOwner().
    For example, "onOK" means "onClick=onOK".
    You can specify several forward conditions by separating them with comma as follows:
    onChanging=onChanging,onChange=onUpdate,onOK
    
    Parameters:
    forward - the forward condition. There are several forms: "onEvent1", "target.onEvent1" and "onEvent1(target.onEvent2)", where target could be "id", "id1/id2" or "${elExpr}". The EL expression must return either a path or a reference to a component.
    Since:
    
    3.0.0
  - getProperties
```
public List<Property> getProperties()
```
    Returns a readonly list of properties (Property) (never null).

public void addProperty(String name,
               String value,
               ConditionImpl cond)
```
    Adds a property initializer. It will initialize a component when created with this info.
    
    Parameters:
    name - the member name. The component must have a valid setter for it.
    value - the value. It might contain expressions (${}).
  - addProperty
```
public void addProperty(String name,
               NativeInfo value,
               ConditionImpl cond)
```
    Adds a property initializer based on the native content. The native content is a XML fragment represented by NativeInfo.

                   ConditionImpl cond)
```
    Adds an event handler.
    
    Parameters:
    name - the event name.
    zscript - the script.
  - getEventHandlerNames
```
public Set<String> getEventHandlerNames()
```
    Returns a readonly collection of event names (String), or an empty collection if no event name is registered.
    To add an event handler, use addEventHandler(java.lang.String, org.zkoss.zk.ui.metainfo.ZScript, org.zkoss.zk.ui.util.ConditionImpl) instead.
    
    Since:
    
    3.0.2
  - addWidgetListener
```
public void addWidgetListener(String name,
                     String script,
                     ConditionImpl cond)
```
    Adds an event listener for the peer widget.
    
    Since:
    
    5.0.0
  - addWidgetOverride
```
public void addWidgetOverride(String name,
                     String script,
                     ConditionImpl cond)
```
    Adds a method or a value to the peer widget. If there was a method with the same name, it will be renamed to $name so can you access it for callback purpose.
```
<label w:setValue="function (value) {
  this.$setValue(value); //old method
}"/>
```
    Parameters:
    script - the client side script. EL expressions are allowed.
    Since:

public void addWidgetAttribute(String name,
                      String value,
                      ConditionImpl cond)
```
    Adds a custom DOM attribute to the peer widget.
    Unlike addWidgetOverride(java.lang.String, java.lang.String, org.zkoss.zk.ui.util.ConditionImpl), the attributes added here are generated directly as DOM attributes at the client. In other words, it is not a property or method of the peer widget.
    
    Parameters:
    name - the name of the attribute. Unlike addWidgetOverride(java.lang.String, java.lang.String, org.zkoss.zk.ui.util.ConditionImpl), the name might contain no alphanumeric characters, such as colon and dash.
    Since:
    
    5.0.3

    addWidgetOverride(java.lang.String, java.lang.String, org.zkoss.zk.ui.util.ConditionImpl)
  - setWidgetClass
```
public void setWidgetClass(String wgtcls)
```
    Sets the widget class.
    
    Parameters:
    wgtcls - the widget class (at the client side). EL expressions are allowed.
    Since:
    
    5.0.2
  - getWidgetClass
```
public String getWidgetClass()
```
    Returns the widget class (might contain EL expressions), or null if not available.
    
    Since:
    
    5.0.2
  - resolveWidgetClass
```
public String resolveWidgetClass(Component comp)
```
    Resolves the widget class, or null if the default is expected. It will evaluate EL expressions if any.
    You rarely need to invoke this method since it is called automatically when applyProperties(org.zkoss.zk.ui.Component) is called.
    
    Parameters:
    comp - the component that the widget class represents at the client.
    Since:
    
    5.0.2
  - getImplementation
```
public String getImplementation()
```
    Returns the class name or an expression returning a class instance, a class name, or a component. It is the same value that setImplementation(java.lang.String) was called. To resolve the real implementation class, use resolveImplementationClass(org.zkoss.zk.ui.Page, org.zkoss.zk.ui.Component).
    Notice that, if a component is returned by the expression, it shall not be assigned to any page.
    
    Since:
    
    3.6.0
  - setImplementation
```
public void setImplementation(String expr)
```
    Sets the string that implements the component.
    
    Parameters:
    expr - the class name, or an expression returning a class instance, a class name, or a component instance.
    Since:
    
    3.6.0
  - newInstance
```
public Component newInstance(Page page,
                    Component parent)
```
    Creates an component based on this info (never null).
    Like ComponentDefinition.newInstance(org.zkoss.zk.ui.Page, java.lang.String), this method doesn't invoke applyProperties(org.zkoss.zk.ui.Component). It is caller's job to invoke them if necessary. Since the value of properties might depend on the component tree, it is better to assign the component with a proper parent before calling applyProperties(org.zkoss.zk.ui.Component).
    
    Since:
    
    3.0.2
  - newInstance
```
public Component newInstance(Page page)
```
    Creates an component based on this info (never null). It is the same as newInstance(page, null).
    If the implementation class (getImplementation()) doesn't have any EL expression, or its EL expression doesn't have reference to the self variable, the result is the same.
    This method is preserved for backward compatibility. It is better to use newInstance(Page, Component).
  - resolveImplementationClass
```
public Class resolveImplementationClass(Page page,
                               Component parent)
                                 throws ClassNotFoundException
```
    Resolves and returns the class for the component represented by this info (never null).
    Unlike getImplementation(), this method will resolve a class name (String) to a class (Class), if necessary.
    
    Parameters:
    page - the page to check whether the class is defined in the page (such as interpreters). Ignored if null. This method will search the class loader of the current thread. If not found, it will search the interpreters of the specified page (Page.getLoadedInterpreters()). Note: this method won't attach the component to the specified page.
    
    Throws:
    
    ClassNotFoundException - if the class not found
    Since:
    
    3.0.2
  - resolveImplementationClass
```
public Class resolveImplementationClass(Page page)
                                 throws ClassNotFoundException
```
    Resolves and returns the class for the component represented by this info (never null). It is the same as resolveImplementationClass(page, null).
    If the implementation class (getImplementation()) doesn't have any EL expression, or its EL expression doesn't have reference to the self variable, the result is the same.
    This method is preserved for backward compatibility. It is better to use resolveImplementationClass(Page, Component).
    
    Throws:
    
    ClassNotFoundException
    Since:
    
    3.0.0
  - getAnnotationMap
```
public AnnotationMap getAnnotationMap()
```
    Returns the annotation map defined in this info, or null if no annotation is ever defined.
  - applyProperties
```
public void applyProperties(Component comp)
```
    Applies the event handlers and properties to the specified component.
    It also invokes ComponentDefinition.applyProperties(org.zkoss.zk.ui.Component).
    Note: custom attributes are not part of ComponentInfo, so they won't be applied here.
    Note: annotations are applied to the component when a component is created. So, this method doesn't and need not to copy them. See also AbstractComponent.AbstractComponent(boolean).
    Note: the widget class (setWidgetClass(java.lang.String)) is set by this method.
    
    Since:
    
    3.0.0
  - evalProperties
```
public Map<String,Object> evalProperties(Map<String,Object> propmap,
                                Page owner,
                                Component parent,
                                boolean defIncluded)
```
    Evaluates and retrieves properties to the specified map from ComponentDefinition (and ComponentInfo).
    
    Parameters:
    propmap - the map to store the retrieved properties (String name, Object value). If null, a HashMap instance is created.
    owner - the owner page; used if parent is null
    parent - the parent component (may be null)
    defIncluded - whether to call ComponentDefinition.evalProperties(java.util.Map<java.lang.String, java.lang.Object>, org.zkoss.zk.ui.Page, org.zkoss.zk.ui.Component).
  - addAnnotation
```
public void addAnnotation(String propName,
                 String annotName,
                 Map<String,String[]> annotAttrs,
                 org.zkoss.util.resource.Location loc)
```
    Adds an annotation to the specified property of this component info.
    
    Parameters:
    propName - the property name. If null, the annotation is associated with the whole component rather than a particular property.
    annotName - the annotation name (never null, nor empty).
    annotAttrs - a map of attributes, or null if no attribute at all. The attribute must be in a pair of strings (String name, String value), or (String name, String[] value).
    loc - the location information of the annotation in the document, or null if not available.
    Since:
    
    6.0.0
  - duplicate
```
public ComponentInfo duplicate()
```
    Duplicates the specified component info but retaining the same but virtual parent-child relationship. It is designed to use with ComposerExt.doBeforeCompose(org.zkoss.zk.ui.Page, org.zkoss.zk.ui.Component, org.zkoss.zk.ui.metainfo.ComponentInfo) to override some properties of the default component info.
    Unlike Object.clone(), the parent-child relation is duplicated but it is 'virtual'. By virtual we mean all the children's parent doesn't reference to the duplicated info (the returned instance). Rather, they reference to the original info being duplicated.
    Since the parent-children relation of the returned info is 'virtual', you can not call appendChild(org.zkoss.zk.ui.metainfo.NodeInfo) or others to change it. If you need to change the parent-children relation, use Object.clone() instead, and then clone the required children.
    Notice, we actually copy the values to the returned info so any change to the original one doesn't affect the duplicated info.

  - resolveForEach
```
public ForEach resolveForEach(Page page,
                     Component comp)
```
    Returns the forEach object if the forEach attribute is defined (or setForEach(java.lang.String, java.lang.String, java.lang.String) is called).
    If comp is not null, both pagedef and page are ignored. If comp is null, page must be specified.
    
    Parameters:
    page - the page. It is used only if comp is null.
    comp - the component.
    
    Returns:
    the forEach object to iterate this info multiple times, or null if this info shall be interpreted only once.
  - setForEach
```
public void setForEach(String expr,
              String begin,
              String end)
```
    Sets the forEach attribute, which is usually an expression.
    
    Parameters:
    expr - the expression to return a collection of objects, or null/empty to denote no iteration.
  - setForEach
```
public void setForEach(String expr,
