Nested Class Summary

Nested Classes
Modifier and Type	Class and Description
`static class`	`JsonRecyclerPools.BoundedPool` `RecyclerPool` implementation that uses a bounded queue (`ArrayBlockingQueue` for recycling instances.
`static class`	`JsonRecyclerPools.ConcurrentDequePool` `RecyclerPool` implementation that uses `ConcurrentLinkedDeque` for recycling instances.
`static class`	`JsonRecyclerPools.LockFreePool` `RecyclerPool` implementation that uses a lock free linked list for recycling instances.
`static class`	`JsonRecyclerPools.NonRecyclingPool` Dummy `RecyclerPool` implementation that does not recycle anything but simply creates new instances when asked to acquire items.
`static class`	`JsonRecyclerPools.ThreadLocalPool` `ThreadLocal`-based `RecyclerPool` implementation used for recycling `BufferRecycler` instances: see `RecyclerPool.ThreadLocalPoolBase` for full explanation of functioning.

Modifier and Type	Method and Description
`static RecyclerPool<BufferRecycler>`	`defaultPool()`
`static RecyclerPool<BufferRecycler>`	`newBoundedPool(int size)` Accessor for constructing a new, non-shared `JsonRecyclerPools.BoundedPool` instance.
`static RecyclerPool<BufferRecycler>`	`newConcurrentDequePool()` Accessor for constructing a new, non-shared `JsonRecyclerPools.ConcurrentDequePool` instance.
`static RecyclerPool<BufferRecycler>`	`newLockFreePool()` Accessor for constructing a new, non-shared `JsonRecyclerPools.LockFreePool` instance.
`static RecyclerPool<BufferRecycler>`	`nonRecyclingPool()` Accessor for getting the shared/global `JsonRecyclerPools.NonRecyclingPool` instance (due to design only one instance ever needed)
