java.lang.Object org.mozilla.javascript.Node org.mozilla.javascript.ast.AstNode org.mozilla.javascript.ast.LabeledStatement
public class LabeledStatement
A labeled statement. A statement can have more than one label. In
this AST representation, all labels for a statement are collapsed into
the "labels" list of a single LabeledStatement
node.
Node type is Token.EXPR_VOID
.

AstNode
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.
toSource
in class AstNode
depth
- the current recursion depth, typically beginning at 0
when called on the root node.public void visit(NodeVisitor v)

in class AstNode
v
- the object to call with this node and its children
