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<typename VectorType>
class Algorithms::OutputOperator< VectorType >

An unary operator base class, intended to output the vectors in AnyData in each step of an iteration.

Definition at line 105 of file operator.h.

Constructor & Destructor Documentation

◆ OutputOperator() [1/2]

template<typename VectorType>
Algorithms::OutputOperator< VectorType >::OutputOperator ( )

Constructor initializing member variables with invalid data.

◆ OutputOperator() [2/2]

template<typename VectorType>
Algorithms::OutputOperator< VectorType >::OutputOperator ( const OutputOperator< VectorType > &  )

The copy constructor is deleted since objects of this class should not be copied.

◆ ~OutputOperator()

template<typename VectorType>
virtual Algorithms::OutputOperator< VectorType >::~OutputOperator ( )

Empty virtual destructor.

Member Function Documentation

◆ initialize_stream()

template<typename VectorType>
void Algorithms::OutputOperator< VectorType >::initialize_stream ( std::ostream &  stream)

Set the stream os to which data is written. If no stream is selected with this function, data goes to deallog.

◆ set_step()

template<typename VectorType >
void Algorithms::OutputOperator< VectorType >::set_step ( const unsigned int  step)

Set the current step.

Definition at line 152 of file operator.h.

◆ operator<<()

template<typename VectorType>
virtual OutputOperator<VectorType>& Algorithms::OutputOperator< VectorType >::operator<< ( const AnyData vectors)

Output all the vectors in AnyData.

Reimplemented in Algorithms::DoFOutputOperator< VectorType, dim, spacedim >.

◆ subscribe()

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

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

◆ unsubscribe()

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

Unsubscribes a user from the object.

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

Definition at line 156 of file

◆ n_subscriptions()

unsigned int Subscriptor::n_subscriptions ( ) const

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 301 of file subscriptor.h.

◆ list_subscribers() [1/2]

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

List the subscribers to the input stream.

Definition at line 318 of file subscriptor.h.

◆ list_subscribers() [2/2]

void Subscriptor::list_subscribers ( ) const

List the subscribers to deallog.

Definition at line 204 of file

◆ serialize()

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

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

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.

Definition at line 310 of file subscriptor.h.
