 package org.mozilla.javascript.ast;
 
AST node for a single 'for (foo in bar)' loop construct in a JavaScript 1.7 Array comprehension. This node type is almost equivalent to a ForInLoop, except that it has no body statement. Node type is org.mozilla.javascript.Token.FOR.

public class ArrayComprehensionLoop extends ForInLoop {
    public ArrayComprehensionLoop() {
    }
    public ArrayComprehensionLoop(int pos) {
        super(pos);
    }
    public ArrayComprehensionLoop(int posint len) {
        super(poslen);
    }
    
    
Returns null for loop body

Returns:
loop body (always null for this node type)
    public AstNode getBody() {
        return null;
    }

    
Throws an exception on attempts to set the loop body.

Parameters:
body loop body
Throws:
java.lang.UnsupportedOperationException
    public void setBody(AstNode body) {
        throw new UnsupportedOperationException("this node type has no body");
    }
    @Override
    public String toSource(int depth) {
        return makeIndent(depth)
                + " for "
                + (isForEach()?"each ":"")
                + "("
                + .toSource(0)
                + " in "
                + .toSource(0)
                + ")";
    }

    
Visits the iterator expression and the iterated object expression. There is no body-expression for this loop type.
    @Override
    public void visit(NodeVisitor v) {

            .visit(v);
            .visit(v);
        }
    }
