public class ArrayComprehensionLoop
extends ForInLoop

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 Token.FOR.

Method Detail

getBody

public AstNode getBody()

Returns null for loop body

Overrides:

getBody in class Loop

Returns:

loop body (always null for this node type)

setBody

public void setBody(AstNode body)

Throws an exception on attempts to set the loop body.

Overrides:

setBody in class Loop

Parameters:

body - loop body

Throws:

java.lang.UnsupportedOperationException

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 ForInLoop

Parameters:

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

visit

public void visit(NodeVisitor v)

Visits the iterator expression and the iterated object expression. There is no body-expression for this loop type.

Overrides:

visit in class ForInLoop

Parameters:

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