## org.mozilla.javascript.ast
Class Jump

    java.lang.Object
      org.mozilla.javascript.Node
          org.mozilla.javascript.ast.AstNode
              org.mozilla.javascript.ast.Jump

All Implemented Interfaces:
  java.lang.Comparable<AstNode>, java.lang.Iterable<Node>

Direct Known Subclasses:
  BreakStatement, ContinueStatement, Label, Scope, SwitchStatement

    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:
    `java.lang.UnsupportedOperationException`

### toSource

    public java.lang.String toSource(int depth)

  Description copied from class: `AstNode`
  Emits source code for this node. Callee is responsible for calling this function recursively on children, incrementing indent as appropriate.

  Note: if the parser was in error-recovery mode, some AST nodes may have `null` children that are expected to be non-`null` when no errors are present. In this situation, the behavior of the `toSource` method is undefined: `toSource` implementations may assume that the AST node is error-free, since it is intended to be invoked only at runtime after a successful parse.

  Specified by:
    `toSource` in class `AstNode`
  Parameters:
    `depth` - the current recursion depth, typically beginning at 0 when called on the root node.
