VerifierCodeVisitor

public VerifierCodeVisitor(ClassNode classNode)

Method Details

visitForLoop

public void visitForLoop(ForStatement statement)

Description copied from class: CodeVisitorSupport

Visits a ForStatement, traversing the collection expression and loop body.

Specified by:

visitForLoop in interface GroovyCodeVisitor

Overrides:

visitForLoop in class CodeVisitorSupport

Parameters:

statement - the for loop statement

visitFieldExpression

public void visitFieldExpression(FieldExpression expression)

Description copied from class: CodeVisitorSupport

Visits a FieldExpression. No traversal is performed as field expressions contain no child expressions.

Specified by:

visitFieldExpression in interface GroovyCodeVisitor

Overrides:

visitFieldExpression in class CodeVisitorSupport

Parameters:

expression - the field expression

visitVariableExpression

public void visitVariableExpression(VariableExpression expression)

Description copied from class: CodeVisitorSupport

Visits a VariableExpression. No traversal is performed as variable expressions contain no child expressions.

Specified by:

visitVariableExpression in interface GroovyCodeVisitor

Overrides:

visitVariableExpression in class CodeVisitorSupport

Parameters:

expression - the variable expression

visitListExpression

public void visitListExpression(ListExpression expression)

Description copied from class: CodeVisitorSupport

Visits a ListExpression, traversing all contained expressions.

Specified by:

visitListExpression in interface GroovyCodeVisitor

Overrides:

visitListExpression in class CodeVisitorSupport

Parameters:

expression - the list expression

visitConstructorCallExpression

public void visitConstructorCallExpression(ConstructorCallExpression call)

Description copied from class: CodeVisitorSupport

Visits a ConstructorCallExpression, traversing its argument list.

Specified by:

visitConstructorCallExpression in interface GroovyCodeVisitor

Overrides:

visitConstructorCallExpression in class CodeVisitorSupport

Parameters:

call - the constructor call expression

assertValidIdentifier

public static void assertValidIdentifier(String name,
 String message,
 ASTNode node)
