Constructor Details

GenericsVisitor

public GenericsVisitor(SourceUnit source)

Method Details

getSourceUnit

protected SourceUnit getSourceUnit()

Description copied from class: ClassCodeVisitorSupport

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)

Description copied from class: ClassCodeVisitorSupport

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)

Description copied from class: ClassCodeVisitorSupport

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

visitConstructorOrMethod

protected void visitConstructorOrMethod(MethodNode node,
 boolean isConstructor)

Description copied from class: ClassCodeVisitorSupport

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 expression)

Description copied from class: CodeVisitorSupport

Overrides:

visitConstructorCallExpression in class CodeVisitorSupport

Parameters:

expression - the constructor call expression

visitDeclarationExpression

public void visitDeclarationExpression(DeclarationExpression expression)

Description copied from class: ClassCodeVisitorSupport

Visits a DeclarationExpression with annotation processing, traversing expression annotations before delegating to parent traversal.

Specified by:

Overrides:

visitDeclarationExpression in class ClassCodeVisitorSupport

Parameters:

expression - the declaration expression to visit

visitArrayExpression

public void visitArrayExpression(ArrayExpression expression)

Description copied from class: CodeVisitorSupport

Visits an ArrayExpression, traversing element expressions and size expressions.

Specified by:

visitArrayExpression in interface GroovyCodeVisitor

Overrides:

visitArrayExpression in class CodeVisitorSupport

Parameters:

expression - the array expression
