Class TLcySLDDomainObject
- All Implemented Interfaces:
ILcdDataObject,ILcdBounded,ILcdShape,ILcdShapeList,ILcdCache,ILcdCloneable,ILcdFeatured,ILcdInvalidateable,Serializable,Cloneable
The default domain object used in Lucy drawing models. It exposes the following properties:
- One
shapethat makes up its geometry. - An OGC Symbology Encoding style, accessible by the methods
getStyleandsetStyle - User-defined properties by implementing
ILcdDataObject, which can be altered and retrieved by callingsetValueandgetValuerespectively.
Instances of this class should be created by using a TLcySLDDomainObjectSupplier.
Note: although this class implements Serializable, instances of this class cannot
be serialized. Use the available drawing model encoders/decoders if you want to store/restore domain
objects.

Method Details
-
setFeatures
Sets the features for this domain object. After calling this method, these features can be accessed through the
ILcdFeaturedinterface.- Parameters:
aFeatures- The features of this domain objects. It must not benull(use an empty array instead). The contents of the array is copied to another array, so changes in the original array are not reflected in this domain object. The array should not contain anynullvalues.

setValue
Description copied from interface:ILcdDataObjectSets the value of the given property for this data object. The implementation is allowed to throw an exception if the given value can't be set.
The given property must be declared in thedata object's typeor in one of its super types. In other words, getDataType().getProperties().contains( aProperty ) should always be true. Otherwise, the implementation should throw anIllegalArgumentException.- Specified by:

setValue
Description copied from interface:ILcdDataObjectConvenience method that sets the value of the property with the given name.

- Specified by:
hasValuein interfaceILcdDataObject- Parameters:
aProperty- the property for which to return whether a value is present or not.- Returns:
trueif this data object has a value for the given property,falseotherwise.
