Class BaseRedSynchronizer.FutureTransformer<RETURN_CLASSIFIER extends BaseRedSynchronizer.ReturnClassifier>

java.lang.Object

io.github.avivcarmis.javared.executor.BaseRedSynchronizer.FutureTransformer<RETURN_CLASSIFIER>

Type Parameters:

RETURN_CLASSIFIER - the matching BaseRedSynchronizer.ReturnClassifier middleware to be returned

Direct Known Subclasses:

BaseRedSynchronizer.FutureTransformer.Locked, BaseRedSynchronizer.FutureTransformer.Unlocked

Enclosing class:

BaseRedSynchronizer

protected abstract static class BaseRedSynchronizer.FutureTransformer<RETURN_CLASSIFIER extends BaseRedSynchronizer.ReturnClassifier>
extends Object

A middleware class to manipulate and transform future status. This middleware will enable the caller to set the type of the expected result of futures by calling either one of the transformation methods: succeed(), finish() or fail, which expect all preconditions to respectively succeed, finish either by success or failure, or to fail. Preconditions are receive as either BaseRedSynchronizer.Result or BaseRedSynchronizer.Marker, and when and transformation method is called, a BaseRedSynchronizer.ReturnClassifier middleware instance is returned.

Modifier and Type	Class and Description
protected static class	BaseRedSynchronizer.FutureTransformer.Locked<RETURN_CLASSIFIER extends BaseRedSynchronizer.ReturnClassifier> A BaseRedSynchronizer.FutureTransformer which leaves the original RETURN_CLASSIFIER parameter in case BaseRedSynchronizer.FutureTransformer.Locked.fail() has been called.
protected static class	BaseRedSynchronizer.FutureTransformer.Unlocked<RETURN_CLASSIFIER extends BaseRedSynchronizer.ReturnClassifier> A BaseRedSynchronizer.FutureTransformer which overrides the RETURN_CLASSIFIER parameter to BaseRedSynchronizer.ReturnClassifier.Classifier0 in case BaseRedSynchronizer.FutureTransformer.Unlocked.fail() has been called.
