Class TraitASTTransformation
java.lang.Object
org.codehaus.groovy.transform.AbstractASTTransformation
org.codehaus.groovy.transform.trait.TraitASTTransformation
- All Implemented Interfaces:
- CompilationUnitAware,- ASTTransformation,- ErrorCollecting
public class TraitASTTransformation
extends AbstractASTTransformation
implements CompilationUnitAware
Handles generation of code for the traits (trait keyword is equivalent to using the @Trait annotation).
 A class annotated with @Trait will generate, instead:
 
- an interface with the same name
- a utility inner class that will be used by the compiler to implement the trait
- potentially a utility inner class to assist with implementing trait fields

visitDescription copied from interface:ASTTransformationThe method is invoked when an AST Transformation is active. For local transformations, it is invoked once each time the local annotation is encountered. For global transformations, it is invoked once for every source unit, which is typically a source file.- Specified by:
- visitin interface- ASTTransformation
- Parameters:
- nodes- The ASTnodes when the call was triggered. Element 0 is the AnnotationNode that triggered this annotation to be activated. Element 1 is the AnnotatedNode decorated, such as a MethodNode or ClassNode. For global transformations it is usually safe to ignore this parameter.
- source- The source unit being compiled. The source unit may contain several classes. For global transformations, information about the AST can be retrieved from this object.
