Module org.htmlunit.corejs

Package org.htmlunit.corejs.javascript.ast

Class Jump

java.lang.Object

org.htmlunit.corejs.javascript.Node

org.htmlunit.corejs.javascript.ast.AstNode

org.htmlunit.corejs.javascript.ast.Jump

All Implemented Interfaces:

Comparable<AstNode>, Iterable<Node>

Direct Known Subclasses:

BreakStatement, ContinueStatement, Label, Scope

public class Jump
extends AstNode

Used for code generation. During codegen, the AST is transformed into an Intermediate Representation (IR) in which loops, ifs, switches and other control-flow statements are rewritten as labeled jumps. If the parser is set to IDE-mode, the resulting AST will not contain any instances of this class.

visit

public void visit(NodeVisitor visitor)

Jumps are only used directly during code generation, and do not support this interface.

Specified by:

visit in class AstNode

Parameters:

visitor - the object to call with this node and its children

Throws:

UnsupportedOperationException - always when called

toSource

public String toSource(int depth)

Jumps are only used directly during code generation, and do not support this interface.

Specified by:

toSource in class AstNode

Parameters:

depth - the current recursion depth, typically beginning at 0 when called on the root node.

Throws:

UnsupportedOperationException - always when called
