Class ByteArrayWriteBuffer.Allocator

java.lang.Object
com.tangosol.io.ByteArrayWriteBuffer.Allocator

All Implemented Interfaces:

MultiBufferWriteBuffer.WriteBufferPool

Enclosing class:

ByteArrayWriteBuffer

public static class ByteArrayWriteBuffer.Allocator

extends java.lang.Object

implements MultiBufferWriteBuffer.WriteBufferPool

Allocator is a WriteBufferPool implementation which allocates a new ByteArrayWriteBuffer on each request to the pool, and does not retain the returned buffer. Essentially it is dummy pool which acts as an allocator.

Field Summary

protected int

m_cb The capacity of the ByteArrayWriteBuffer instances to allocate.

Constructor Summary

ByteArrayWriteBuffer.Allocator(int cb)
Construct an Allocator for ByteArrayWriteBuffers of a given size.

Method Summary

WriteBuffer	allocate(int cbPreviousTotal) Allocate a new ByteArrayWriteBuffer.
int	getMaximumCapacity() Determine the largest amount of aggregate WriteBuffer capacity that this factory can provide.
void	release(WriteBuffer buffer) Release the supplied buffer into the pool.

Field Detail

m_cb

protected int m_cb

The capacity of the ByteArrayWriteBuffer instances to allocate.

Constructor Detail

ByteArrayWriteBuffer.Allocator

public ByteArrayWriteBuffer.Allocator(int cb)

Construct an Allocator for ByteArrayWriteBuffers of a given size.

Parameters:

cb - the capacity of the ByteArrayWriteBuffer to be allocated

Method Detail

getMaximumCapacity

public int getMaximumCapacity()

Determine the largest amount of aggregate WriteBuffer capacity that this factory can provide.

Specified by:

getMaximumCapacity in interface MultiBufferWriteBuffer.WriteBufferPool

Returns:

the number of bytes that can be stored in the WriteBuffer objects that may be returned from this factory

allocate

public WriteBuffer allocate(int cbPreviousTotal)

Allocate a new ByteArrayWriteBuffer.

Specified by:

allocate in interface MultiBufferWriteBuffer.WriteBufferPool

Parameters:

cbPreviousTotal - unused

Returns:

a new ByteArrayWriteBuffer with this Allocator's capacity

release

public void release(WriteBuffer buffer)

Release the supplied buffer into the pool.

This method is a no op.

Specified by:

release in interface MultiBufferWriteBuffer.WriteBufferPool

Parameters:

buffer - unused
