xform - the active transform

body - the statement block being generated

cNode - the owning class

props - the candidate properties

Returns:

true if validation succeeds

createPropInit

public Statement createPropInit(AbstractASTTransformation xform,
 AnnotationNode anno,
 ClassNode cNode,
 PropertyNode pNode,
 Parameter namedArgsMap)

Create a statement that will initialize the property including any defensive copying. Null if no statement should be added.

Specified by:

createPropInit in class PropertyHandler

Parameters:

xform - the transform being processed

anno - the '@ImmutableBase' annotation node

cNode - the classnode containing the property
