ChannelBuffers (Netty 3.10.5.Final API文档

java.lang.Object
- org.jboss.netty.buffer.ChannelBuffers

```
public final class ChannelBuffers
extends java.lang.Object
```
Creates a new ChannelBuffer by allocating new space or by wrapping or copying existing byte arrays, byte buffers and a string.
Use static import
This classes is intended to be used with Java 5 static import statement:
```
 import static org.jboss.netty.buffer.ChannelBuffers.*;

 ChannelBuffer heapBuffer    = buffer(128);
 ChannelBuffer directBuffer  = directBuffer(256);
 ChannelBuffer dynamicBuffer = dynamicBuffer(512);
 ChannelBuffer wrappedBuffer = wrappedBuffer(new byte[128], new byte[256]);
 ChannelBuffer copiedBuffe r = copiedBuffer(ByteBuffer.allocate(128));
 
```
Allocating a new buffer
Three buffer types are provided out of the box.
- buffer(int) allocates a new fixed-capacity heap buffer.
- directBuffer(int) allocates a new fixed-capacity direct buffer.
- dynamicBuffer(int) allocates a new dynamic-capacity heap buffer, whose capacity increases automatically as needed by a write operation.
Creating a wrapped buffer
Wrapped buffer is a buffer which is a view of one or more existing byte arrays and byte buffers. Any changes in the content of the original array or buffer will be visible in the wrapped buffer. Various wrapper methods are provided and their name is all wrappedBuffer(). You might want to take a look at the methods that accept varargs closely if you want to create a buffer which is composed of more than one array to reduce the number of memory copy.
Creating a copied buffer
Copied buffer is a deep copy of one or more existing byte arrays, byte buffers or a string. Unlike a wrapped buffer, there's no shared data between the original data and the copied buffer. Various copy methods are provided and their name is all copiedBuffer(). It is also convenient to use this operation to merge multiple buffers into one buffer.
Miscellaneous utility methods
This class also provides various utility methods to help implementation of a new buffer type, generation of hex dump and swapping an integer's byte order.
