Method Detail

mayCacheNow

boolean mayCacheNow()

Returns:

whether a computation that started at the moment of this RecursionGuard.StackStamp instance creation does not depend on any re-entrant recursive results. When such non-reliable results exist in the thread's call stack, returns false, otherwise true.

If you use this with RecursionGuard.doPreventingRecursion(Key, boolean, com.intellij.openapi.util.Computable<T>), then the RecursionManager.markStack()+mayCacheNow() should be outside of recursion prevention call. Otherwise even the outer recursive computation result won't be cached. In particular, doPreventingRecursion calls should be inside your CachedValue provider, not outside cached value access.
