示例1: ProcessClosures
public override void ProcessClosures(Context ctx)
{
if(LeftOperand is LambdaNode)
LeftOperand.ProcessClosures(ctx);
if (RightOperand is LambdaNode)
RightOperand.ProcessClosures(ctx);
var leftType = LeftOperand.GetExpressionType(ctx);
var rightGetter = RightOperand as GetMemberNode;
if (!IsLeft && leftType.IsCallableType() && rightGetter != null)
{
if (rightGetter.TypeHints.IsEmpty())
{
var returnType = ctx.ResolveMethod(leftType, "Invoke").ReturnType;
rightGetter.TypeHints = new List<TypeSignature> {TypeSignature.Parse(returnType.FullName)};
}
}
var rightType = RightOperand.GetExpressionType(ctx);
if (rightGetter != null)
rightGetter.TypeHints.Clear();
if (!IsLeft && leftType.IsCallableType() && rightType.IsCallableType())
{
if (!ctx.CanCombineDelegates(leftType, rightType))
Error(Translations.CompilerMessages.DelegatesNotCombinable, leftType, rightType);
var argTypes = ctx.WrapDelegate(leftType).ArgumentTypes;
var argGetters = argTypes.Select((a, id) => Expr.GetArg(id)).Cast<NodeBase>().ToArray();
if (LeftOperand is GetMemberNode)
(LeftOperand as GetMemberNode).TypeHints.Clear();
_Method = ctx.CurrentScope.CreateClosureMethod(ctx, argTypes, ctx.WrapDelegate(rightType).ReturnType);
_Method.Body =
