示例1: IsIfReturnExpr
private static JsIfNode IsIfReturnExpr(JsAstNode node, out JsAstNode condition, ref JsAstNode matchExpression)
{
// set the condition to null initially
condition = null;
// must be an if-node with no false block, and a true block with one statement
var ifNode = node as JsIfNode;
if (ifNode != null
&& ifNode.FalseBlock == null
&& ifNode.TrueBlock != null
&& ifNode.TrueBlock.Count == 1)
{
// and that one statement needs to be a return statement
var returnNode = ifNode.TrueBlock[0] as JsReturnNode;
if (returnNode != null)
{
if (matchExpression == null
|| matchExpression.IsEquivalentTo(returnNode.Operand))
{
// either we don't care what the return expression is,
// or we do care and it's a match.
matchExpression = returnNode.Operand;
condition = ifNode.Condition;
}
}
}
// but we will only return the if-node IF the matchedExpression and the
// condition are both non-null (our TRUE state)
return condition != null && matchExpression != null ? ifNode : null;
}
