Detailed Description

The MLBookProc class.

This class contains various auxiliary methods. It should be created before any other MLBookProc library objects.

Warning

Only one MLBookProc object per application is allowed, otherwise behavior is undefined.

Member Function Documentation

create()

std::shared_ptr< MLBookProc > MLBookProc::create ( )

static
