Detailed Description

template<class ScalarType, class MV, class OP>
class Belos::StatusTestGeneralOutput< ScalarType, MV, OP >

A special StatusTest for printing other status tests.

StatusTestGeneralOutput is a wrapper around any another StatusTest that calls StatusTest::print() on the underlying object on calls to StatusTestGeneralOutput::checkStatus(). The frequency and occasion of the printing can be dictated according to some parameters passed to StatusTestGeneralOutput::StatusTestGeneralOutput().

Constructor & Destructor Documentation

template<class ScalarType , class MV , class OP >
Belos::StatusTestGeneralOutput< ScalarType, MV, OP >::StatusTestGeneralOutput ( const Teuchos::RCP< OutputManager< ScalarType > > &  printer,
Teuchos::RCP< StatusTest< ScalarType, MV, OP > >  test,
int  mod = 1,
int  printStates = Passed 
) [inline]

Constructor.

The StatusTestGeneralOutput requires an OutputManager for printing the underlying StatusTest on calls to checkStatus(), as well as an underlying StatusTest.

The last two parameters, described below, in addition to the verbosity level of the OutputManager, control when printing is called. When both the mod criterion and the printStates criterion are satisfied, the status test will be printed to the OutputManager with MsgType of StatusTestDetails.

Parameters:
[in] mod A positive number describes how often the output should be printed. On every call to checkStatus(), an internal counter is incremented. Printing may only occur when this counter is congruent to zero modulo mod. Default: 1 (attempt to print on every call to checkStatus())
[in] printStates A combination of StatusType values for which the output may be printed. Default: Passed (attempt to print whenever checkStatus() will return Passed)

Member Function Documentation

template<class ScalarType , class MV , class OP >
StatusType Belos::StatusTestGeneralOutput< ScalarType, MV, OP >::checkStatus ( Iteration< ScalarType, MV, OP > *  solver  )  [inline, virtual]

Check and return status of underlying StatusTest.

This method calls checkStatus() on the StatusTest object passed in the constructor. If appropriate, the method will follow this call with a call to print() on the underlying object, using the OutputManager passed via the constructor with verbosity level StatusTestDetails.

The internal counter will be incremented during this call, but only after performing the tests to decide whether or not to print the underlying StatusTest. This way, the very first call to checkStatus() following initialization or reset() will enable the underlying StatusTest to be printed, regardless of the mod parameter, as the current number of calls will be zero.

If the specified Teuchos::RCP for the child class is Teuchos::null, then calling checkStatus() will result in a StatusTestError std::exception being thrown.

Returns:
StatusType indicating whether the underlying test passed or failed.

void Belos::StatusTestGeneralOutput< ScalarType, MV, OP >::reset (  )  [inline, virtual]

Informs the status test that it should reset its internal configuration to the uninitialized state.

This resets the cached state to an Undefined state and calls reset() on the underlying test. It also resets the counter for the number of calls to checkStatus().
