| <pre>public class <span class="typeNameLabel">BufferUtil</span> |
| extends java.lang.Object</pre> |
| <div class="block">Buffer utility methods. |
| <p>The standard JVM <code>ByteBuffer</code> can exist in two modes: In fill mode the valid |
| data is between 0 and pos; In flush mode the valid data is between the pos and the limit. |
| The various ByteBuffer methods assume a mode and some of them will switch or enforce a mode: |
| Allocate and clear set fill mode; flip and compact switch modes; read and write assume fill |
| and flush modes. This duality can result in confusing code such as: |
| </p> |
| <pre> |
| buffer.clear(); |
| channel.write(buffer); |
| </pre> |
| <p> |
| Which looks as if it should write no data, but in fact writes the buffer worth of garbage. |
| </p> |
| <p> |
| The BufferUtil class provides a set of utilities that operate on the convention that ByteBuffers |
| will always be left, passed in an API or returned from a method in the flush mode - ie with |
| valid data between the pos and limit. This convention is adopted so as to avoid confusion as to |
| what state a buffer is in and to avoid excessive copying of data that can result with the usage |
| of compress.</p> |
| <p> |
| Thus this class provides alternate implementations of <a href="#allocate(int)"><code>allocate(int)</code></a>, |
| <a href="#allocateDirect(int)"><code>allocateDirect(int)</code></a> and <a href="#clear(java.nio.ByteBuffer)"><code>clear(ByteBuffer)</code></a> that leave the buffer |
| in flush mode. Thus the following tests will pass: |
| </p> |
| <pre> |
| ByteBuffer buffer = BufferUtil.allocate(1024); |
| assert(buffer.remaining()==0); |
| BufferUtil.clear(buffer); |
| assert(buffer.remaining()==0); |
| </pre> |
| <p>If the BufferUtil methods <a href="#fill(java.nio.ByteBuffer,byte%5B%5D,int,int)"><code>fill(ByteBuffer, byte[], int, int)</code></a>, |
| <a href="#append(java.nio.ByteBuffer,byte%5B%5D,int,int)"><code>append(ByteBuffer, byte[], int, int)</code></a> or <a href="#put(java.nio.ByteBuffer,java.nio.ByteBuffer)"><code>put(ByteBuffer, ByteBuffer)</code></a> are used, |
| then the caller does not need to explicitly switch the buffer to fill mode. |
| If the caller wishes to use other ByteBuffer bases libraries to fill a buffer, |
| then they can use explicit calls of #flipToFill(ByteBuffer) and #flipToFlush(ByteBuffer, int) |
| to change modes. Note because this convention attempts to avoid the copies of compact, the position |
| is not set to zero on each fill cycle and so its value must be remembered: |
| </p> |
| <pre> |
| int pos = BufferUtil.flipToFill(buffer); |
| try |
| { |
| buffer.put(data); |
| } |
| finally |
| { |
| flipToFlush(buffer, pos); |
| } |
| </pre> |
| <p> |
| The flipToFill method will effectively clear the buffer if it is empty and will compact the buffer if there is no space. |
