class OdBmCommandContext : public OdEdCommandContext;

BmCommandContext.h

This class defines the interface for I/O and *database* access for custom commands during their execution.

Client applications that invoke custom commands, should use an instance of this class (or a subclass) to pass to the OdEdCommandStack::executeCommand function. Using this class instead of a true instance of OdEdCommandContext provides custom commands with *database* access. 

{group:OdDb_Classes} 

 

Returns a *database*, for use in a custom command.
