```
public abstract class IoBuffer
extends java.lang.Object
implements java.lang.Comparable<IoBuffer>
```
A byte buffer used by MINA applications.
This is a replacement for ByteBuffer. Please refer to ByteBuffer documentation for preliminary usage. MINA does not use NIO ByteBuffer directly for two reasons:
- It doesn't provide useful getters and putters such as fill, get/putString, and get/putAsciiInt() enough.
- It is difficult to write variable-length data due to its fixed capacity
Allocation

You can allocate a new heap buffer.
```
 IoBuffer buf = IoBuffer.allocate(1024, false);
 
```
you can also allocate a new direct buffer:
```
 IoBuffer buf = IoBuffer.allocate(1024, true);
 
```
or you can set the default buffer type.
```
 // Allocate heap buffer by default.
 IoBuffer.setUseDirectBuffer(false);
 // A new heap buffer is returned.
 IoBuffer buf = IoBuffer.allocate(1024);
 
```
Wrapping existing NIO buffers and arrays

This class provides a few wrap(...) methods that wraps any NIO buffers and byte arrays.
AutoExpand

Writing variable-length data using NIO ByteBuffers is not really easy, and it is because its size is fixed. IoBuffer introduces autoExpand property. If autoExpand property is true, you never get BufferOverflowException or IndexOutOfBoundsException (except when index is negative). It automatically expands its capacity and limit value. For example:
```
 String greeting = messageBundle.getMessage("hello");
 IoBuffer buf = IoBuffer.allocate(16);
 // Turn on autoExpand (it is off by default)
 buf.setAutoExpand(true);
 buf.putString(greeting, utf8encoder);
 
```
The underlying ByteBuffer is reallocated by IoBuffer behind the scene if the encoded data is larger than 16 bytes in the example above. Its capacity will double, and its limit will increase to the last position the string is written.

AutoShrink

You might also want to decrease the capacity of the buffer when most of the allocated memory area is not being used. IoBuffer provides autoShrink property to take care of this issue. If autoShrink is turned on, IoBuffer halves the capacity of the buffer when compact() is invoked and only 1/4 or less of the current capacity is being used.
You can also shrink() method manually to shrink the capacity of the buffer.
The underlying ByteBuffer is reallocated by IoBuffer behind the scene, and therefore buf() will return a different ByteBuffer instance once capacity changes. Please also note compact() or shrink() will not decrease the capacity if the new capacity is less than the minimumCapacity() of the buffer.
Derived Buffers

Derived buffers are the buffers which were created by duplicate(), slice(), or asReadOnlyBuffer(). They are useful especially when you broadcast the same messages to multiple IoSessions. Please note that the buffer derived from and its derived buffers are not both auto-expandable neither auto-shrinkable. Trying to call setAutoExpand(boolean) or setAutoShrink(boolean) with true parameter will raise an IllegalStateException.

Changing Buffer Allocation Policy

IoBufferAllocator interface lets you override the default buffer management behavior. There are two allocators provided out-of-the-box:
- SimpleBufferAllocator (default)
- CachedBufferAllocator
You can implement your own allocator and use it by calling setAllocator(IoBufferAllocator).
