Detailed Description

LOCA abstract interface for extended groups, derived from the NOX::Abstract::Group, i.e., an abstract interface for "super" groups that have an underlying group component.

Concrete implemenations of this interface must provide implementations of all of the methods in the NOX::Abstract::Group interface as well as the additional interface defined here.

Teuchos::RCP< const LOCA::MultiContinuation::AbstractGroup > LOCA::Extended::MultiAbstractGroup::getBaseLevelUnderlyingGroup ( ) const
virtual

Return base-level underlying group.

This method is intended for composite groups (such as extended bifurcation groups) which have an underlying group as a data member. This method is supposed to return the base level group and has a default recursive implementation that should work in most cases.
