ASTTransformationVisitor (Groovy 3.0.1)

java.lang.Object
- org.codehaus.groovy.ast.CodeVisitorSupport
- - org.codehaus.groovy.ast.ClassCodeVisitorSupport
  - - org.codehaus.groovy.transform.ASTTransformationVisitor

All Implemented Interfaces:

GroovyClassVisitor, GroovyCodeVisitor, ErrorCollecting
```
public final class ASTTransformationVisitor
extends ClassCodeVisitorSupport
```
This class handles the invocation of the ASTAnnotationTransformation when it is encountered by a tree walk. One instance of each exists for each phase of the compilation it applies to. Before invocation the
ASTTransformationCollectorCodeVisitor will add a list of annotations that this visitor should be concerned about. All other annotations are ignored, whether or not they are GroovyASTTransformation annotated or not.
A Two-pass method is used. First all candidate annotations are added to a list then the transformations are called on those collected annotations. This is done to avoid concurrent modification exceptions during the AST tree walk and allows the transformations to alter any portion of the AST tree. Hence annotations that are added in this phase will not be processed as transformations. They will only be handled in later phases (and then only if the type was in the AST prior to any AST transformations being run against it).

- Method Detail
  - getSourceUnit
```
protected SourceUnit getSourceUnit()
```
    Specified by:
    
    getSourceUnit in class ClassCodeVisitorSupport
  - visitClass
```
public void visitClass(ClassNode classNode)
```
    Main loop entry.
    First, it delegates to the super visitClass so we can collect the relevant annotations in an AST tree walk.
    Second, it calls the visit method on the transformation for each relevant annotation found.
    
    Specified by:
    
    visitClass in interface GroovyClassVisitor
    
    Overrides:
    
    visitClass in class ClassCodeVisitorSupport
    
    Parameters:
    
    classNode - the class to visit
  - visitAnnotations
```
public void visitAnnotations(AnnotatedNode node)
```
    Adds the annotation to the internal target list if a match is found.
    
    Overrides:
    
    visitAnnotations in class ClassCodeVisitorSupport
    
    Parameters:
    
    node - the node to be processed
  - addPhaseOperations

public static void addPhaseOperations(CompilationUnit compilationUnit)
```
  - addGlobalTransformsAfterGrab
```
public static void addGlobalTransformsAfterGrab(ASTTransformationsContext context)
