Constructor Detail

DefaultByteBufferPool

public DefaultByteBufferPool(boolean direct,
                             int bufferSize)

Parameters:

direct - If this implementation should use direct buffers

bufferSize - The buffer size to use

DefaultByteBufferPool

public DefaultByteBufferPool(boolean direct,
                             int bufferSize,
                             int maximumPoolSize,
                             int threadLocalCacheSize,
                             int leakDecetionPercent)

Parameters:

direct - If this implementation should use direct buffers

bufferSize - The buffer size to use

maximumPoolSize - The maximum pool size, in number of buffers, it does not include buffers in thread local caches

threadLocalCacheSize - The maximum number of buffers that can be stored in a thread local cache

DefaultByteBufferPool

public DefaultByteBufferPool(boolean direct,
                             int bufferSize,
                             int maximumPoolSize,
                             int threadLocalCacheSize)

Parameters:

direct - If this implementation should use direct buffers

bufferSize - The buffer size to use

maximumPoolSize - The maximum pool size, in number of buffers, it does not include buffers in thread local caches

threadLocalCacheSize - The maximum number of buffers that can be stored in a thread local cache

Method Detail

getBufferSize

public int getBufferSize()

Specified by:

getBufferSize in interface ByteBufferPool

isDirect

public boolean isDirect()

Specified by:

isDirect in interface ByteBufferPool

allocate

public PooledByteBuffer allocate()

Specified by:

allocate in interface ByteBufferPool

getArrayBackedPool

public ByteBufferPool getArrayBackedPool()

Description copied from interface: ByteBufferPool

If this byte buffer pool corresponds to an array backed pool then this will return itself. Otherwise it will return an array backed pool that contains buffers of the same size.

Specified by:

getArrayBackedPool in interface ByteBufferPool

Returns:

An array backed pool of the same size

close

public void close()

Specified by:

close in interface ByteBufferPool

Specified by:

close in interface Closeable

Specified by:

close in interface AutoCloseable

finalize

protected void finalize()
                 throws Throwable

Overrides:

finalize in class Object

Throws:

Throwable
