ByteArrayWriteBuffer.Allocator (Java API Reference for Oracle® Coherence Community Edition)

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.

  - 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
