BufferByteArray

java.lang.Object
- org.apache.mina.util.byteaccess.AbstractByteArray
- - org.apache.mina.util.byteaccess.BufferByteArray

All Implemented Interfaces:

ByteArray, IoAbsoluteReader, IoAbsoluteWriter

Direct Known Subclasses:

ByteArrayPool.DirectBufferByteArray
```
public abstract class BufferByteArray
extends AbstractByteArray
```
A ByteArray backed by a IoBuffer. This class is abstract. Subclasses need to override the free() method. An implementation backed by a heap IoBuffer can be created with a SimpleByteArrayFactory.

- Field Detail
  - bb
```
protected IoBuffer bb
```
    The backing IoBuffer.
- Constructor Detail
  - BufferByteArray
```
public BufferByteArray(IoBuffer bb)
```
    Creates a new instance of BufferByteArray and uses the supplied IoBuffer to back this class
    
    Parameters:
    
    bb - The backing buffer
- Method Detail
  - getIoBuffers
```
public java.lang.Iterable<IoBuffer> getIoBuffers()
```
    Description copied from interface: ByteArray
    
    Get the sequence of IoBuffers that back this array. Compared to getSingleIoBuffer(), this method should be relatively efficient for all implementations.
  - getSingleIoBuffer
```
public IoBuffer getSingleIoBuffer()
```
    Description copied from interface: ByteArray
    
    Gets a single IoBuffer that backs this array. Some implementations may initially have data split across multiple buffers, so calling this method may require a new buffer to be allocated and populated.
  - slice
```
public ByteArray slice(int index,
                       int length)
```
    Description copied from interface: IoAbsoluteReader
    
    Creates an array with a view of part of this array.
  - free
```
public abstract void free()
```
    Description copied from interface: ByteArray
    
    Remove any resources associated with this object. Using the object after this method is called may result in undefined behaviour.
  - cursor
```
public ByteArray.Cursor cursor()
```
    Description copied from interface: ByteArray
    
    Get a cursor starting at index 0 (which may not be the start of the array).
  - cursor
```
public ByteArray.Cursor cursor(int index)
```
    Description copied from interface: ByteArray
    
    Get a cursor starting at the given index.
  - first
```
public int first()
```
    Description copied from interface: IoAbsoluteReader
    
    Get the index of the first byte that can be accessed.
  - last
```
public int last()
```
    Description copied from interface: IoAbsoluteReader
    
    Gets the index after the last byte that can be accessed.
  - order
```
public java.nio.ByteOrder order()
```
    Description copied from interface: IoAbsoluteReader
    
    Gets the order of the bytes.
  - order
```
public void order(java.nio.ByteOrder order)
```
    Description copied from interface: ByteArray
    
    Set the byte order of the array.
