Package net.groboclown.retval.impl

Behind-the-scenes implementations for the top-level interfaces. These can change arbitrarily between versions, even patch versions, so do not rely upon these for library stability.

The code here attempts to optimize memory and performance based on usage patterns. The primary motivation around the break-down is for optimizing memory, especially since these objects are expected to have a short life-cycle and potentially large numbers of objects created.

Interface Summary

Interface	Description
ReturnTypeFactory	An abstract factory pattern for creating the return type objects.

Class Summary

Class	Description
CollectionUtil	Internal helper class for working with collections.
MonitoredFactory	Generates monitored versions of the return types.
MonitoredReturnProblem<T>	A shared implementation of the Ret* interfaces, which only contains problems.
MonitoredReturnValue<T>	Intended to be a version of the Ret* classes, with no error and a value.
MonitoredRetVoidOk	Monitored version of RetVal with an ok state (no problems).
RetGenerator	Central handler for creating Ret* instances.
SimpleFactory	Generates unmonitored, streamlined implementations.
SimpleReturnProblem<T>	A shared implementation of the Ret* interfaces, which only contains problems and is not monitored.
SimpleReturnValue<T>	Intended to be a version of the Ret* classes, with no error and a value, and has no monitor.
SimpleRetVoidOk	Unmonitored version of RetVoid with an OK state.
