public class InnerClassVisitor
extends InnerClassVisitorHelper

Processes inner classes during compilation, handling the creation of synthetic fields and parameters needed for inner class instances to reference their enclosing instances. This visitor identifies and transforms inner class constructor calls to pass the appropriate enclosing instance references.

Constructor Summary

Constructors

Constructor	Description
InnerClassVisitor(CompilationUnit cu, SourceUnit su)	Creates a new inner class visitor.

Method Summary

Modifier and Type	Method	Description
protected SourceUnit	getSourceUnit()	Provides access to the SourceUnit for error reporting during visitation.
void	visitClass(ClassNode node)	Visits a ClassNode, processing its annotations, package, imports, contents, and object initializers.
void	visitClosureExpression(ClosureExpression closure)	Visits a ClosureExpression with annotation processing, traversing parameter annotations before delegating to parent traversal.
void	visitConstructorCallExpression(ConstructorCallExpression call)	Visits a ConstructorCallExpression, traversing its argument list.
protected void	visitConstructorOrMethod(MethodNode node, boolean isConstructor)	Visits a constructor or method node (implementation detail for both visit methods).
void	visitField(FieldNode node)	Visits a FieldNode, processing its annotations and initial value expression if present.
protected void	visitObjectInitializerStatements(ClassNode node)	Visits all object initializer statements in a class, typically static or instance initialization blocks.
void	visitProperty(PropertyNode node)	Visits a PropertyNode, processing its annotations, initial value expression, and getter/setter blocks if present.

Constructor Details

InnerClassVisitor

public InnerClassVisitor(CompilationUnit cu,
 SourceUnit su)

Creates a new inner class visitor.

Parameters:

cu - the compilation unit (currently unused but kept for API compatibility)

su - the source unit for error reporting

Method Details

getSourceUnit

protected SourceUnit getSourceUnit()

Provides access to the SourceUnit for error reporting during visitation. Implementations must override this method.

Specified by:

getSourceUnit in class ClassCodeVisitorSupport

Returns:

the source unit for this visitor

visitClass

public void visitClass(ClassNode node)

Visits a ClassNode, processing its annotations, package, imports, contents, and object initializers.

Specified by:

visitClass in interface GroovyClassVisitor

Overrides:

visitClass in class ClassCodeVisitorSupport

Parameters:

node - the class node to visit

visitField

public void visitField(FieldNode node)

Visits a FieldNode, processing its annotations and initial value expression if present.

Specified by:

visitField in interface GroovyClassVisitor

Overrides:

visitField in class ClassCodeVisitorSupport

Parameters:

node - the field node to visit

visitProperty

public void visitProperty(PropertyNode node)

Visits a PropertyNode, processing its annotations, initial value expression, and getter/setter blocks if present.

Specified by:

visitProperty in interface GroovyClassVisitor

Overrides:

visitProperty in class ClassCodeVisitorSupport

Parameters:

node - the property node to visit

visitClosureExpression

public void visitClosureExpression(ClosureExpression closure)

Visits a ClosureExpression with annotation processing, traversing parameter annotations before delegating to parent traversal.

Specified by:

visitClosureExpression in interface GroovyCodeVisitor

Overrides:

visitClosureExpression in class ClassCodeVisitorSupport

Parameters:

closure - the closure expression to visit

visitObjectInitializerStatements

protected void visitObjectInitializerStatements(ClassNode node)

Visits all object initializer statements in a class, typically static or instance initialization blocks.

Overrides:

visitObjectInitializerStatements in class ClassCodeVisitorSupport

Parameters:

node - the class node containing initializer statements

visitConstructorOrMethod

protected void visitConstructorOrMethod(MethodNode node,
 boolean isConstructor)

Visits a constructor or method node (implementation detail for both visit methods). Processes the node's annotations, all parameter annotations, and code block.

Overrides:

visitConstructorOrMethod in class ClassCodeVisitorSupport

Parameters:

node - the method or constructor node

isConstructor - true if node is a constructor, false if it is a method

visitConstructorCallExpression

public void visitConstructorCallExpression(ConstructorCallExpression call)

Visits a ConstructorCallExpression, traversing its argument list.

Specified by:

visitConstructorCallExpression in interface GroovyCodeVisitor

Overrides:

visitConstructorCallExpression in class CodeVisitorSupport

Parameters:

call - the constructor call expression
