public final class JsonRecyclerPools
extends Object

Set of RecyclerPool implementations to be used by the default JSON-backed JsonFactory for recycling BufferRecycler containers.

Nested Class Summary

Nested Classes

Modifier and Type	Class	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.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.

Method Summary

Modifier and Type	Method	Description
static RecyclerPool<BufferRecycler>	defaultPool()	Method to call to get the default recycler pool instance: as of Jackson 3.0 and later this is same as calling newConcurrentDequePool().
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>	nonRecyclingPool()	Accessor for getting the shared/global JsonRecyclerPools.NonRecyclingPool instance (due to design only one instance ever needed)
static RecyclerPool<BufferRecycler>	sharedBoundedPool()	Accessor for getting the shared/global JsonRecyclerPools.BoundedPool instance.
static RecyclerPool<BufferRecycler>	sharedConcurrentDequePool()	Accessor for getting the shared/global JsonRecyclerPools.ConcurrentDequePool instance.
static RecyclerPool<BufferRecycler>	threadLocalPool()	Accessor for getting the shared/global JsonRecyclerPools.ThreadLocalPool instance (due to design only one instance ever needed)

JsonRecyclerPools

public JsonRecyclerPools()

Method Details

defaultPool

public static RecyclerPool<BufferRecycler> defaultPool()

Method to call to get the default recycler pool instance: as of Jackson 3.0 and later this is same as calling newConcurrentDequePool().

Returns:

the default RecyclerPool implementation to use if no specific implementation desired.

threadLocalPool

public static RecyclerPool<BufferRecycler> threadLocalPool()

Accessor for getting the shared/global JsonRecyclerPools.ThreadLocalPool instance (due to design only one instance ever needed)

Returns:

Globally shared instance of JsonRecyclerPools.ThreadLocalPool

nonRecyclingPool

public static RecyclerPool<BufferRecycler> nonRecyclingPool()

Accessor for getting the shared/global JsonRecyclerPools.NonRecyclingPool instance (due to design only one instance ever needed)

Returns:

Globally shared instance of JsonRecyclerPools.NonRecyclingPool.

sharedConcurrentDequePool

public static RecyclerPool<BufferRecycler> sharedConcurrentDequePool()

Accessor for getting the shared/global JsonRecyclerPools.ConcurrentDequePool instance.

Returns:

Globally shared instance of JsonRecyclerPools.NonRecyclingPool.

newConcurrentDequePool

public static RecyclerPool<BufferRecycler> newConcurrentDequePool()

Accessor for constructing a new, non-shared JsonRecyclerPools.ConcurrentDequePool instance.

Returns:

Globally shared instance of JsonRecyclerPools.NonRecyclingPool.

sharedBoundedPool

public static RecyclerPool<BufferRecycler> sharedBoundedPool()

Accessor for getting the shared/global JsonRecyclerPools.BoundedPool instance.

Returns:

Globally shared instance of JsonRecyclerPools.BoundedPool.

newBoundedPool

public static RecyclerPool<BufferRecycler> newBoundedPool(int size)

Accessor for constructing a new, non-shared JsonRecyclerPools.BoundedPool instance.

Parameters:

size - Maximum number of values to pool

Returns:

Globally shared instance of JsonRecyclerPools.BoundedPool.
