</h1>
  <div class="markdown level0 summary"><p>This interface defines a source of entropy coded data and methods to
transfer it in a code-block by code-block basis. In each call to
'getNextCodeBlock()' a new coded code-block is returned. The code-block are
retruned in no specific-order.</p>
<pre><code>       &lt;p&gt;This interface is the source of data for the rate allocator. See the
       'PostCompRateAllocator' class.&lt;/p&gt;&lt;p&gt;For each coded-code-block the entropy-coded data is returned along with
       the rate-distortion statistics in a 'CBlkRateDistStats' object.&lt;/p&gt;

        <td class="markdown level1 summary"><p>Returns the next coded code-block in the current tile for the specified
component, as a copy (see below). The order in which code-blocks are
returned is not specified. However each code-block is returned only
once and all code-blocks will be returned if the method is called 'N'
times, where 'N' is the number of code-blocks in the tile. After all
the code-blocks have been returned for the current tile calls to this
method will return 'null'.</p>
<pre><code>       &lt;p&gt;When changing the current tile (through 'setTile()' or 'nextTile()')
       this method will always return the first code-block, as if this method
       was never called before for the new current tile.&lt;/p&gt;&lt;p&gt;The data returned by this method is always a copy of the internal
       data of this object, if any, and it can be modified &quot;in place&quot; without
       any problems after being returned.&lt;/p&gt;
