Class NewExpression

  • 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
