`ChannelBuffer`	`getBuffer(java.nio.ByteOrder endianness, byte[] array, int offset, int length)` Returns a `ChannelBuffer` whose content is equal to the sub-region of the specified `array`.
`ChannelBuffer`	`getBuffer(java.nio.ByteOrder endianness, int capacity)` Returns a `ChannelBuffer` with the specified `endianness` and `capacity`.
`ChannelBuffer`	`getBuffer(int capacity)` Returns a `ChannelBuffer` with the specified `capacity`.
`java.nio.ByteOrder`	`getDefaultOrder()` Returns the default endianness of the `ChannelBuffer` which is returned by `getBuffer(int)`.

- 方法详细资料
  - getBuffer
```
ChannelBuffer getBuffer(int capacity)
```
    Returns a ChannelBuffer with the specified capacity. This method is identical to getBuffer(getDefaultOrder(), capacity).
    
    参数:
    capacity - the capacity of the returned ChannelBuffer
    
    返回:
    a ChannelBuffer with the specified capacity, whose readerIndex and writerIndex are 0
  - getBuffer
```
ChannelBuffer getBuffer(java.nio.ByteOrder endianness,
                      int capacity)
```
    Returns a ChannelBuffer with the specified endianness and capacity.
    
    参数:
    endianness - the endianness of the returned ChannelBuffer
    capacity - the capacity of the returned ChannelBuffer
    
    返回:
    a ChannelBuffer with the specified endianness and capacity, whose readerIndex and writerIndex are 0
  - getBuffer
```
ChannelBuffer getBuffer(byte[] array,
                      int offset,
                      int length)
```
    Returns a ChannelBuffer whose content is equal to the sub-region of the specified array. Depending on the factory implementation, the returned buffer could wrap the array or create a new copy of the array. This method is identical to getBuffer(getDefaultOrder(), array, offset, length).
    
    参数:
    array - the byte array
    offset - the offset of the byte array
    length - the length of the byte array
    
    返回:
    a ChannelBuffer with the specified content, whose readerIndex and writerIndex are 0 and (length - offset) respectively
  - getBuffer
```
ChannelBuffer getBuffer(java.nio.ByteOrder endianness,
                      byte[] array,
                      int offset,
                      int length)
```
    Returns a ChannelBuffer whose content is equal to the sub-region of the specified array. Depending on the factory implementation, the returned buffer could wrap the array or create a new copy of the array.
    
    参数:
    endianness - the endianness of the returned ChannelBuffer
    array - the byte array
    offset - the offset of the byte array
    length - the length of the byte array
    
    返回:
    a ChannelBuffer with the specified content, whose readerIndex and writerIndex are 0 and (length - offset) respectively
  - getBuffer
```
ChannelBuffer getBuffer(java.nio.ByteBuffer nioBuffer)
```
    Returns a ChannelBuffer whose content is equal to the sub-region of the specified nioBuffer. Depending on the factory implementation, the returned buffer could wrap the nioBuffer or create a new copy of the nioBuffer.
    
    参数:
    nioBuffer - the NIO ByteBuffer
    
    返回:
    a ChannelBuffer with the specified content, whose readerIndex and writerIndex are 0 and nioBuffer.remaining() respectively
  - getDefaultOrder
```
java.nio.ByteOrder getDefaultOrder()
```
    Returns the default endianness of the ChannelBuffer which is returned by getBuffer(int).
    
    返回:
    the default endianness of the ChannelBuffer which is returned by getBuffer(int)
