Detailed Description

Common bulletin::Visitor base for visitors that modify the bulletin.

This assumes a fully decoded bulletin.

Member Function Documentation

virtual const Var& wreport::bulletin::BaseVisitor::do_bitmap ( Varcode  code, Varcode  rep_code, Varcode  delayed_code, const Opcodes &  ops  )

virtual

Request processing of a data present bitmap.

Parameters

code	The C modifier code that defines the bitmap
rep_code	The R replicator that defines the bitmap
delayed_code	The B delayed replicator that defines the bitmap length (it is 0 if the length is encoded in the YYY part of rep_code
ops	The replicated opcodes that define the bitmap

Returns

The bitmap that has been processed.

Implements wreport::bulletin::Visitor.
