Method Details

priority

public int priority()

Specified by:

priority in interface TransformWithPriority

setCompilationUnit

public void setCompilationUnit(CompilationUnit compilationUnit)

Description copied from interface: CompilationUnitAware

Sets the compilation unit currently applying this transformation.

Specified by:

setCompilationUnit in interface CompilationUnitAware

Parameters:

compilationUnit - the active compilation unit

visit

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

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.

Specified by:

visit in 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.

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.
