@JSFComponent(name="f:viewParam",
              bodyContent="JSP",
              tagClass="org.apache.myfaces.taglib.core.ViewParamTag")

                returnType="int",
                longDesc="The max number or characters allowed for this param")
public class UIViewParameter
extends UIInput

TODO: documentation on jsp and pld are not the same. It appear two params: maxlength and for, but no property getter and setter founded here. If maxlength is used, we can put something like this: JSFJspProperty(name = "maxlength", returnType = "java.lang.String")

UIViewParameter

Method Detail

getFamily

public String getFamily()

Overrides:

getFamily in class UIInput

decode

public void decode(FacesContext context)

Description copied from class: UIComponentBase

Check the submitted form parameters for data associated with this component. This default implementation delegates to this component's renderer if there is one, and otherwise ignores the call.

Overrides:

decode in class UIInput

encodeAll

public void encodeAll(FacesContext context)
               throws IOException

Overrides:

encodeAll in class UIComponentBase

Throws:

IOException

getName

public String getName()

getStringValue

public String getStringValue(FacesContext context)

getStringValueFromModel

public String getStringValueFromModel(FacesContext context)
                               throws ConverterException

Throws:

ConverterException

isImmediate

@JSFProperty(tagExcluded=true)
public boolean isImmediate()

Description copied from class: UIInput

A boolean value that identifies the phase during which action events should fire.

During normal event processing, action methods and action listener methods are fired during the "invoke application" phase of request processing. If this attribute is set to "true", these methods are fired instead at the end of the "apply request values" phase.

Specified by:

isImmediate in interface EditableValueHolder

Overrides:

isImmediate in class UIInput

isRendered

@JSFProperty(tagExcluded=true)
public boolean isRendered()

Description copied from class: UIComponentBase

A boolean value that indicates whether this component should be rendered. Default value: true.

Overrides:

isRendered in class UIComponentBase

processValidators

public void processValidators(FacesContext context)

Overrides:

processValidators in class UIInput

setName

public void setName(String name)

updateModel

public void updateModel(FacesContext context)

Overrides:

updateModel in class UIInput

getConvertedValue

protected Object getConvertedValue(FacesContext context,
                                   Object submittedValue)

Description copied from class: UIInput

Convert the provided object to the desired value.

If there is a renderer for this component, then call the renderer's getConvertedValue method. While this can of course be implemented in any way the renderer desires, it typically performs exactly the same processing that this method would have done anyway (ie that described below for the no-renderer case).

Otherwise:

• If the submittedValue is not a String then just return the submittedValue unconverted.
• If there is no "value" value-binding then just return the submittedValue unconverted.
• Use introspection to determine the type of the target property specified by the value-binding, and then use Application.createConverter to find a converter that can map from String to the required type. Apply the converter to the submittedValue and return the result.

Overrides:

getConvertedValue in class UIInput

getFacesContext

protected FacesContext getFacesContext()

Overrides:

getFacesContext in class UIComponentBase
