      <section><p>This is the generic class to store coded (compressed) code-block. It stores
the compressed data as well as the necessary side-information.</p>
<pre><code>       &lt;p&gt;This class is normally not used. Instead the EncRDCBlk, EncLyrdCBlk and
       the DecLyrdCBlk subclasses are used.&lt;/p&gt;

      <h4><a class="xref" href="CSJ2K.j2k.entropy.Progression.html">Progression</a></h4>
      <section><p>This class holds one of the different progression orders defined in
the bit stream. The type(s) of progression order are defined in the
ProgressionType interface. A Progression object is totally defined
by its component start and end, resolution level start and end and
layer start and end indexes. If no progression order change is
defined, there is only Progression instance.</p>

      <h4><a class="xref" href="CSJ2K.j2k.entropy.ProgressionSpec.html">ProgressionSpec</a></h4>
      <section><p>This class extends ModuleSpec class for progression type(s) and progression
order changes holding purposes.</p>
<pre><code>       &lt;p&gt;It stores  the progression type(s) used in the  codestream. There can be
       several progression  type(s) if  progression order  changes are  used (POC
       markers).&lt;/p&gt;
