Method Detail

copyPropertyDescriptors

protected List<PropertyDescriptor<?>> copyPropertyDescriptors()

Creates a copied list of the property descriptors and returns it.

Returns:

a copy of the property descriptors.

copyPropertyValues

protected Map<PropertyDescriptor<?>,Object> copyPropertyValues()

Creates a copied map of the values of the properties and returns it.

Returns:

a copy of the values

ignoredProperties

public Set<PropertyDescriptor<?>> ignoredProperties()

Return the properties that are effectively ignored due to the configuration of the rule and values held by other properties. This can be used to disable corresponding widgets in a UI.

Specified by:

ignoredProperties in interface PropertySource

Returns:

the properties that are ignored

definePropertyDescriptor

public void definePropertyDescriptor(PropertyDescriptor<?> propertyDescriptor)

Define a new property via a PropertyDescriptor.

Specified by:

definePropertyDescriptor in interface PropertySource

Parameters:

propertyDescriptor - The property descriptor.

getName

public abstract String getName()

Gets the name of the property source. This is e.g. the rule name or the report name.

Returns:

the name

getPropertyDescriptor

public PropertyDescriptor<?> getPropertyDescriptor(String name)

Get the PropertyDescriptor for the given property name.

Specified by:

getPropertyDescriptor in interface PropertySource

Parameters:

name - The name of the property.

Returns:

The PropertyDescriptor for the named property, null if there is no such property defined.

hasDescriptor

public boolean hasDescriptor(PropertyDescriptor<?> descriptor)

Returns whether this Rule has the specified PropertyDescriptor.

Specified by:

hasDescriptor in interface PropertySource

Parameters:

descriptor - The PropertyDescriptor for which to check.

Returns:

boolean true if the descriptor is present, false otherwise.

getPropertyDescriptors

public List<PropertyDescriptor<?>> getPropertyDescriptors()

Get the PropertyDescriptors for all defined properties. The properties are returned sorted by UI order.

Specified by:

getPropertyDescriptors in interface PropertySource

Returns:

The PropertyDescriptors in UI order.

getProperty

public <T> T getProperty(PropertyDescriptor<T> propertyDescriptor)

Get the typed value for the given property.

Specified by:

getProperty in interface PropertySource

Type Parameters:

T - The underlying type of the property descriptor.

Parameters:

propertyDescriptor - The property descriptor.

Returns:

The property value.

setProperty

public <T> void setProperty(PropertyDescriptor<T> propertyDescriptor,
                            T value)

Set the property value specified (will be type-checked)

Specified by:

setProperty in interface PropertySource

Type Parameters:

T - The underlying type of the property descriptor.

Parameters:

propertyDescriptor - The property descriptor.

value - The value to set.

getPropertiesByPropertyDescriptor

public Map<PropertyDescriptor<?>,Object> getPropertiesByPropertyDescriptor()

Returns all the current property values for the receiver or an immutable empty map if none are specified.

Specified by:

getPropertiesByPropertyDescriptor in interface PropertySource

Returns:

all current property values or a empty map.

usesDefaultValues

public boolean usesDefaultValues()

Returns whether this Rule uses default values for properties.

Specified by:

usesDefaultValues in interface PropertySource

Returns:

boolean true if the properties all have default values, false otherwise.

useDefaultValueFor

public void useDefaultValueFor(PropertyDescriptor<?> desc)

Clears out any user-specified value for the property allowing it to use the default value in the descriptor.

Specified by:

useDefaultValueFor in interface PropertySource

Parameters:

desc - the property to clear out

dysfunctionReason

public String dysfunctionReason()

Returns a description of why the receiver may be dysfunctional. Usually due to missing property values or some kind of conflict between values. Returns null if the receiver is ok.

Specified by:

dysfunctionReason in interface PropertySource

Returns:

String
