Detailed Description

template<class ScalarType, class MV, class OP>
class Anasazi::StatusTestCombo< ScalarType, MV, OP >

Status test for forming logical combinations of other status tests.

Test types include StatusTestCombo::OR, StatusTestCombo::AND, StatusTestCombo::SEQOR and StatusTestCombo::SEQAND. The StatusTestCombo::OR and StatusTestCombo::AND tests evaluate all of the tests, in the order they were passed to the StatusTestCombo. The StatusTestCombo::SEQOR and StatusTestCombo::SEQAND run only the tests necessary to determine the final outcome, short-circuiting on the first test that conclusively decides the outcome. More formally, StatusTestCombo::SEQAND runs the tests in the order they were given to the StatusTestCombo class and stops after the first test that evaluates Failed. StatusTestCombo::SEQOR run the tests in the order they were given to the StatusTestCombo class and stops after the first test that evaluates Passed.

TestStatus Anasazi::StatusTestCombo< ScalarType, MV, OP >::checkStatus ( Eigensolver< ScalarType, MV, OP > * solver )

Check status as defined by test.

template<class ScalarType , class MV , class OP >

std::vector<int> Anasazi::StatusTestCombo< ScalarType, MV, OP >::whichVecs ( ) const

inlinevirtual

Get the indices for the vectors that passed the test.

This returns some combination of the passing vectors from the tests comprising the StatusTestCombo. The nature of the combination depends on the StatusTestCombo::ComboType:

StatusTestCombo::SEQOR, StatusTestCombo::OR - whichVecs() returns the union of whichVecs() from all evaluated constituent tests
StatusTestCombo::SEQAND, StatusTestCombo::AND - whichVecs() returns the intersection of whichVecs() from all evaluated constituent tests

void Anasazi::StatusTestCombo< ScalarType, MV, OP >::removeTest ( const Teuchos::RCP< StatusTest< ScalarType, MV, OP > > & test )

Removes a test from the combination, if it exists in the tester.

This also resets the test status to Undefined, if a test was removed.

template<class ScalarType , class MV , class OP >

void Anasazi::StatusTestCombo< ScalarType, MV, OP >::reset ( )

virtual

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

The StatusTestCombo class has no internal state, but children classes might, so this method will call reset() on all child status tests. It also resets the test status to Undefined.

Implements Anasazi::StatusTest< ScalarType, MV, OP >.

Definition at line 271 of file AnasaziStatusTestCombo.hpp.

template<class ScalarType , class MV , class OP >

void Anasazi::StatusTestCombo< ScalarType, MV, OP >::clearStatus ( )

virtual

Clears the results of the last status test.

This should be distinguished from the reset() method, as it only clears the cached result from the last status test, so that a call to getStatus() will return Undefined. This is necessary for the StatusTestCombo::SEQOR and StatusTestCombo::SEQAND tests in the StatusTestCombo class, which may short circuit and not evaluate all of the StatusTests contained in them.

Implements Anasazi::StatusTest< ScalarType, MV, OP >.

template<class ScalarType , class MV , class OP >
