Direct Known Subclasses:

EntityInstancePool

public class SimpleInstancePool

extends ServiceAdapter

implements InstancePool

This is a simple implementation of the InstancePool interface based on Sean's original InstancePool class. A super-basic implementation of a Class instance pool. Possibly use the generic pooling library for this in the future, but even if not add configurable elements like max size, min size, etc.
