public class TLcdFeaturedShapeList
extends TLcdShapeList
implements 
ILcdFeatured
, ILcdDataObject

This class provides an implementation of ILcdShapeList that is also ILcdDataObject and ILcdFeatured.

This class is typically used in situations that require both ILcdDataObject and ILcdFeatured. In case only ILcdDataObject is required, TLcdDataObjectShapeList should be used.

A TLcdFeaturedShapeList has a display name, which can be set freely. If the display name has not been set explicitly, it is retrieved from the list of features through a default display name index. The value of this index can be set; its default value is 0.

This class is thread-safe for concurrent read-only access of its contents. For read-write access, external locking must be used. Such locking is typically done at the model level.

getValue

public Object getValue(TLcdDataProperty aProperty)

Description copied from interface: ILcdDataObject

If the property is a collection, the returned value will never be null. If the property has not been set, an empty collection of the appropriate type will be returned (Set, List or Map).

The property must not be null, and must be declared in the data object's type or in one of its super types. Otherwise an IllegalArgumentException is thrown.

Specified by:

getValue in interface ILcdDataObject

Parameters:

aProperty - the property for which the value is to be returned

Returns:

the value of the given property for this data object

See ILcdDataObject.getValue(TLcdDataProperty) for more information.

Specified by:

getValue in interface ILcdDataObject

Parameters:

aPropertyName - the name of the property of which the value is to be returned

Returns:

the value of the property with the given name

See Also:
