ApplicationsLib Namespace Reference

Detailed Description

The LinearSolverLibrarySetup takes care of proper initialization and shutting down of an external linear solver library. The concrete implementation is chosen by the build system. An object of this class must be created at the beginning of the scope where it is used. When the scope closes (or the object is destroyed explicitly) library shutting down functions are automatically called. The default implementation is empty providing polymorphic behaviour when using this class.
