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 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.

Constructor Detail

Allocator

public 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
