Abstract class which block preconditioner factories in Teko should be based on.
virtual LinearOp buildPreconditionerOperator(BlockedLinearOp &blo, BlockPreconditionerState &state) const =0
Function that is called to build the preconditioner for the linear operator that is passed in.
An implementation of a state object for block preconditioners.
virtual void initializeFromParameterList(const Teuchos::ParameterList &pl)
Initialize from a parameter list.
LinearOp buildPreconditionerOperator(BlockedLinearOp &blo, BlockPreconditionerState &state) const
