public void visit(ASTNode[] nodes, SourceUnit source)

Implements org.codehaus.groovy.transform.ASTTransformation.visit.

Doc from org.codehaus.groovy.transform.ASTTransformation.visit.

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:ASTNode[]

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:SourceUnit

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.
