visit

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

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.

hasIncludeGenerated

public static boolean hasIncludeGenerated(ClassNode cNode)

makeThrowStmt

public static ThrowStatement makeThrowStmt(String variableName)

markAsProcessed

public static void markAsProcessed(MethodNode mn)

Mark a method as already processed.

Parameters:

mn - the method node to be considered already processed
