public class LegacyHashMapPropertyHandler
extends ImmutablePropertyHandler

The @Immutable transformation in earlier versions of Groovy tried to be smart in the case of an immutable class with a single HashMap property, the supplied Map constructor tried to be compatible with both expected tuple behavior and expected named-argument behavior by peeking into the supplied map and guessing as to which approach might be applicable. Recent versions of Groovy now allow both @TupleConstructor and @MapConstructor annotations to co-exist which provide's a more flexible solution to this problem. While more flexible, the new approach isn't fully compatible with the previous approach. If for some reason you need the old behavior, you can try this property handler. Some features of the new approach won't be available to you.

Since:

2.5.0

Description copied from class: PropertyHandler

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

Overrides:

createPropInit in class ImmutablePropertyHandler

Parameters:

xform - the transform being processed

anno - the '@ImmutableBase' annotation node

cNode - the classnode containing the property

pNode - the property node to initialize

namedArgsMap - an "args" Map if the property value should come from a named arg map or null if not
