Direct Known Subclasses:

TranslateToGlobalTransform

public abstract class AbstractClassNodeTransformer
extends AbstractTransformer

This Transformer can be used to transform ClassNode nodes. To locate the classes you want to transform, a criteria in form of Closure can be passed in the constructor. The criteria must be a Closure receiving as unique parameter a ClassNode and returning a Boolean value. If the closure returns true, then the transformation will be applied.

There are some static methods creating some default criterias:

• Criterias.byClassNodeNameContains(String)
• Criterias.byClassNodeNameStartsWith(String)
• Criterias.byClassNodeNameEndsWith(String)

Since:

0.2.0

Constructor Detail

AbstractClassNodeTransformer

public AbstractClassNodeTransformer(SourceUnit sourceUnit,
                                    Closure<Boolean> criteria)

Every instance needs the source unit and the name of the class it's going to transform. To find classes eligible to be transformed by this Transformer a Closure returning a boolean is used as a criteria. You can create your own criteria or use one of the static methods present in this class. These methods will create a pre-defined criteria. The Closure used as a criteria will receive a ClassNode and return a Boolean value. If the closure returns true then the transformation will be apply, if not the ClassNode will be discarded.

Parameters:

sourceUnit - Needed to apply scope

criteria - used to locate target classes look for the qualified class)

Since:

0.2.0
