Modifier and Type	Class and Description
protected static interface	AbstractMemoryManager.TrimAware This is a marker interface indicating a particular `Buffer` implementation can be trimmed.

Field Summary

Modifier and Type	Field and Description
public static final int	DEFAULT_MAX_BUFFER_SIZE The maximum size of the memory pool that is to be maintained by either the MemoryManager itself or any `ThreadLocalPool`s.
protected final int	maxBufferSize
protected final DefaultMonitoringConfig<MemoryProbe>	monitoringConfig Basic monitoring support.

Constructor Summary

Access	Constructor and Description
public	AbstractMemoryManager() Creates a new `AbstractMemoryManager` using a max buffer size of 65536.
public	AbstractMemoryManager(final int max size of the maintained buffer. maxBufferSize) Creates a new `AbstractMemoryManager` using the specified buffer size.

Method Summary

Modifier and Type	Method and Description
protected Object	Returns: an memory buffer, or `null` if the requested size exceeds the remaining free memory of the `ThreadLocalPool`. allocateFromPool(final ThreadLocalPool<E> the `ThreadLocalPool` to allocate from. threadLocalCache, final int the amount to allocate. size) Allocate a `Buffer` using the provided `ThreadLocalPool`.
protected abstract Object	createJmxManagementObject() Returns: the JMX `Object` used to register/deregister with the JMX runtime.
public int	getMaxBufferSize() Returns: the max size of the buffer maintained by this `AbstractMemoryManager`.
public int	Returns: the size of local thread memory pool. getReadyThreadBufferSize() Get the size of local thread memory pool.
protected static ThreadLocalPool<E>	Returns: thread associated buffer pool. This method may return `null` if the current thread doesn't have a buffer pool associated with it. getThreadLocalPool() Get thread associated buffer pool.

allocateFromPool back to summary

allocateFromPool	back to summary
protected Object allocateFromPool(final ThreadLocalPool<E> threadLocalCache, final int size) Allocate a `Buffer` using the provided `ThreadLocalPool`. Parameters threadLocalCache:ThreadLocalPool<E> the `ThreadLocalPool` to allocate from. size:int the amount to allocate. Returns:Object an memory buffer, or `null` if the requested size exceeds the remaining free memory of the `ThreadLocalPool`.

protected Object allocateFromPool(final ThreadLocalPool<E> threadLocalCache, final int size)

Allocate a Buffer using the provided ThreadLocalPool.

Parameters

threadLocalCache:ThreadLocalPool<E>: the ThreadLocalPool to allocate from.
size:int: the amount to allocate.

Returns:Object

an memory buffer, or null if the requested size exceeds the remaining free memory of the ThreadLocalPool.

createJmxManagementObject	back to summary
protected abstract Object createJmxManagementObject() Returns:Object the JMX `Object` used to register/deregister with the JMX runtime.

getMaxBufferSize	back to summary
public int getMaxBufferSize() Returns:int the max size of the buffer maintained by this `AbstractMemoryManager`.

getReadyThreadBufferSize	back to summary
public int getReadyThreadBufferSize() Get the size of local thread memory pool. Returns:int the size of local thread memory pool.

getReadyThreadBufferSize

back to summary

public int getReadyThreadBufferSize()

Get the size of local thread memory pool.

Returns:int: the size of local thread memory pool.

getThreadLocalPool back to summary

getThreadLocalPool	back to summary
protected static ThreadLocalPool<E> getThreadLocalPool() Get thread associated buffer pool. Returns:ThreadLocalPool<E> thread associated buffer pool. This method may return `null` if the current thread doesn't have a buffer pool associated with it.

protected static ThreadLocalPool<E> getThreadLocalPool()

Get thread associated buffer pool.

Returns:ThreadLocalPool<E>: thread associated buffer pool. This method may return null if the current thread doesn't have a buffer pool associated with it.
