Package org.codehaus.groovy.transform

Class ActiveObjectASTTransformation

java.lang.Object

org.codehaus.groovy.transform.AbstractASTTransformation

org.codehaus.groovy.transform.ActiveObjectASTTransformation

All Implemented Interfaces:

ASTTransformation, ErrorCollecting

public class ActiveObjectASTTransformation
extends AbstractASTTransformation

Handles the ActiveObject annotation, transforming ActiveMethod-annotated methods to route through an internal actor for serialised execution.

Inspired by GPars' ActiveObjectASTTransformation, adapted for Groovy's built-in Actor infrastructure.

Since:

6.0.0

Description copied from interface: ASTTransformation

The 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.

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.
