Subscriptor functionality

Classes derived from Subscriptor provide a facility to subscribe to this object. This is mostly used by the SmartPointer class.

Detailed Description

template<class FE>
class FETools::FEFactory< FE >

A concrete class for factory objects creating finite elements of a given degree.

The class's get() function generates a finite element object of the type given as template argument, and with the degree (however the finite element class wishes to interpret this number) given as argument to get().

Member Function Documentation

◆ get() [1/2]

template<class FE >
virtual std::unique_ptr<FiniteElement<FE::dimension, FE::space_dimension> > FETools::FEFactory< FE >::get ( const unsigned int  degree) const
overridevirtual

Create a FiniteElement and return a pointer to it.

Implements FETools::FEFactoryBase< FE::dimension, FE::space_dimension >.

◆ get() [2/2]

template<class FE >
virtual std::unique_ptr<FiniteElement<FE::dimension, FE::space_dimension> > FETools::FEFactory< FE >::get ( const Quadrature< 1 > &  quad) const
overridevirtual

Create a FiniteElement from a quadrature formula (currently only implemented for FE_Q) and return a pointer to it.

Implements FETools::FEFactoryBase< FE::dimension, FE::space_dimension >.

◆ subscribe()

void Subscriptor::subscribe ( std::atomic< bool > *const  validity,
const std::string &  identifier = "" 
) const
inherited

Subscribes a user of the object by storing the pointer validity. The subscriber may be identified by text supplied as identifier.

Definition at line 136 of file subscriptor.cc.

◆ unsubscribe()

void Subscriptor::unsubscribe ( std::atomic< bool > *const  validity,
const std::string &  identifier = "" 
) const
inherited

Unsubscribes a user from the object.

Note
The identifier and the validity pointer must be the same as the one supplied to subscribe().

Definition at line 156 of file subscriptor.cc.

◆ n_subscriptions()

unsigned int Subscriptor::n_subscriptions ( ) const
inlineinherited

Return the present number of subscriptions to this object. This allows to use this class for reference counted lifetime determination where the last one to unsubscribe also deletes the object.

Definition at line 300 of file subscriptor.h.

◆ list_subscribers() [1/2]

template<typename StreamType >
void Subscriptor::list_subscribers ( StreamType &  stream) const
inlineinherited

List the subscribers to the input stream.

Definition at line 317 of file subscriptor.h.

◆ list_subscribers() [2/2]

void Subscriptor::list_subscribers ( ) const
inherited

List the subscribers to deallog.

Definition at line 204 of file subscriptor.cc.

◆ serialize()

template<class Archive >
void Subscriptor::serialize ( Archive &  ar,
const unsigned int  version 
)
inlineinherited

Read or write the data of this object to or from a stream for the purpose of serialization.

This function does not actually serialize any of the member variables of this class. The reason is that what this class stores is only who subscribes to this object, but who does so at the time of storing the contents of this object does not necessarily have anything to do with who subscribes to the object when it is restored. Consequently, we do not want to overwrite the subscribers at the time of restoring, and then there is no reason to write the subscribers out in the first place.
