All Implemented Interfaces:

java.lang.Comparable<AstNode>, java.lang.Iterable<Node>

public class NewExpression
extends FunctionCall

New expression. Node type is Token.NEW.

NewExpression :
      MemberExpression
      new NewExpression

This node is a subtype of FunctionCall, mostly for internal code sharing. Structurally a NewExpression node is very similar to a FunctionCall, so it made a certain amount of sense.

Method Detail

getInitializer

public ObjectLiteral getInitializer()

Returns initializer object, if any.

Returns:

extra initializer object-literal expression, or null if not specified.

setInitializer

public void setInitializer(ObjectLiteral initializer)

Sets initializer object. Rhino supports an experimental syntax of the form new expr [ ( arglist ) ] [initializer], in which initializer is an object literal that is used to set additional properties on the newly-created expr object.

Parameters:

initializer - extra initializer object. Can be null.

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.

Overrides:

toSource in class FunctionCall

Parameters:

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

visit

public void visit(NodeVisitor v)

Visits this node, the target, and each argument. If there is a trailing initializer node, visits that last.

Overrides:

visit in class FunctionCall

Parameters:

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