Class Yield

  • All Implemented Interfaces:
    Comparable<AstNode>, Iterable<Node>

    public class Yield
    extends AstNode
    AST node for JavaScript 1.7 yield expression or statement. Node type is Token.YIELD.

    Yield :
       yield [no LineTerminator here] [non-paren Expression] ;

    • Method Detail

      • getValue

        public AstNode getValue()
        Returns yielded expression, null if none
      • setValue

        public void setValue​(AstNode expr)
        Sets yielded expression, and sets its parent to this node.
        expr - the value to yield. Can be null.
      • toSource

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

        public void visit​(NodeVisitor v)
        Visits this node, and if present, the yielded value.
        Specified by:
        visit in class AstNode
        v - the object to call with this node and its children
