+/** Interprets resource data read from a resource file.
+
+To use an instance of this class, pass the buffer containing the resource 
+data to it by calling SetBuffer().
+
+The buffer containing the resource data is created by RResourceFile::AllocReadL()/CResourceFile::AllocReadL() 
+which reads the specified resource into it.
+
+The current position within the buffer is always maintained and any request 
+for data is always supplied from the current position. The current position 
+is always updated .
+
+Expected behaviour when assignment operator or copy constructor is called:
+The class doesn't have assignment operator and copy constructor, so the compiler generated
+ones will be used. The buffer used by the source class instance will be shared with the 
+destination class instance. However source and destination instances will have their own 
+current position pointers, both pointed initially to the same buffer position.
