An internal action does not cause the Exit and Entry actions to be triggered, and does not change the state of the state machine /// From f393f52d28f7dfd40c1a0315e63d8dafc6a01e9e Mon Sep 17 00:00:00 2001 From: Taylor Grote Date: Fri, 9 Mar 2018 13:09:53 -0600 Subject: [PATCH 20/64] Update TryFindLocalHandler to evaluate guard conditions only once Update actual trigger behavior results to evaluate instantly by just adding a ToArray(). If a IEnumerable with processing, like a Select(), is kept that way, it will only go through that processing once it's enumerated. This causes the guard conditions of transitions to be evaluated twice, which was a waste of everybody's time. --- src/Stateless/StateRepresentation.cs | 20 ++++++++++---------- 1 file changed, 10 insertions(+), 10 deletions(-) diff --git a/src/Stateless/StateRepresentation.cs b/src/Stateless/StateRepresentation.cs index cd98a9a6..822e0c69 100644 --- a/src/Stateless/StateRepresentation.cs +++ b/src/Stateless/StateRepresentation.cs @@ -66,7 +66,7 @@ bool TryFindLocalHandler(TTrigger trigger, object[] args, out TriggerBehaviourRe // Guard functions executed var actual = possible - .Select(h => new TriggerBehaviourResult(h, h.UnmetGuardConditions(args))); + .Select(h => new TriggerBehaviourResult(h, h.UnmetGuardConditions)).ToArray(); handlerResult = TryFindLocalHandlerResult(trigger, actual, r => !r.UnmetGuardConditions.Any()) ??
