Collection of types and exceptions used within the Belos solvers.
Exception thrown to signal error in a status test during Belos::StatusTest::checkStatus().
StatusTest()
Constructor.
Pure virtual base class which describes the basic interface to the linear solver iteration.
virtual StatusType checkStatus(Iteration< ScalarType, MV, OP > *iSolver)=0
Check convergence status: Unconverged, Converged, Failed.
A pure virtual class for defining the status tests for the Belos iterative solvers.
StatusType
Whether the StatusTest wants iteration to stop.
Definition: BelosTypes.hpp:189
virtual void print(std::ostream &os, int indent=0) const =0
Output formatted description of stopping test to output stream.
virtual ~StatusTest()
Destructor.
BelosError(const std::string &what_arg)
Definition: BelosTypes.hpp:62
StatusTestError(const std::string &what_arg)
virtual void reset()=0
Informs the convergence test that it should reset its internal configuration to the initialized state...
Parent class to all Belos exceptions.
Definition: BelosTypes.hpp:60
virtual StatusType getStatus() const =0
Return the result of the most recent CheckStatus call.
virtual void printStatus(std::ostream &os, StatusType type) const
Output the result of the most recent CheckStatus call.
Belos header file which uses auto-configuration information to include necessary C++ headers...
