public abstract class AbstractMethodNodeTransformer
extends AbstractTransformer

This Transformer can be used to transform MethodNode 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 MethodNode 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.byMethodNodeNameContains(String)
• Criterias.byMethodNodeNameStartsWith(String)
• Criterias.byMethodNodeNameEndsWith(String)

Since:

0.2.0

Constructor Detail

AbstractMethodNodeTransformer

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

Deprecated.

Every instance needs the source unit and the name of the class it's going to transform. To find methods 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 MethodNode and return a Boolean value. If the closure returns true then the transformation will be apply, if not the MethodNode will be discarded.

Parameters:

sourceUnit - Needed to apply scope

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

Since:

0.2.0
