◆ caughtMooseException()

template<typename RangeType >
void ThreadedElementLoop< RangeType >::caughtMooseException ( MooseException )
overridevirtual

Called if a MooseException is caught anywhere during the computation.

The single input parameter taken is a MooseException object.

Reimplemented from ThreadedElementLoopBase< RangeType >.

FEProblemBase & _fe_problem
virtual void setException(const std::string &message)
Set an exception.
static Threads::spin_mutex threaded_element_mutex
This mutex is used by all derived classes of the ThreadedElementLoop.

◆ keepGoing()

template<typename RangeType>
virtual bool ThreadedElementLoop< RangeType >::keepGoing ( )
inlineoverridevirtual

Whether or not the loop should continue.

Returns
true to keep going, false to stop.

Reimplemented from ThreadedElementLoopBase< RangeType >.

45 { return !_fe_problem.hasException(); }
FEProblemBase & _fe_problem
virtual bool hasException()
Whether or not an exception has occurred.

◆ neighborSubdomainChanged()

template<typename RangeType >
void ThreadedElementLoop< RangeType >::neighborSubdomainChanged ( )
overridevirtual

Called every time the neighbor subdomain changes (i.e.

the subdomain of this neighbor is not the same as the subdomain of the last neighbor). Beware of over-using this! You might think that you can do some expensive stuff in here and get away with it... but there are applications that have TONS of subdomains....
