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.
bool isCompatible(const Thyra::LinearOpSourceBase< double > &fwdOpSrc) const
is this operator compatiable with the preconditioner factory?
An implementation of a state object for block preconditioners.
