Member Enumeration Documentation

◆ OutputStyle

List of possible description output formats.

Capitalization chosen for similarity to ParameterHandler::OutputStyle.

Enumerator
Machine 

Simple text suitable for machine parsing in the static public member functions for all of the built in inheriting classes.

Preferably human readable, but machine parsing is more critical.

Text 

Easily human readable plain text format suitable for plain text documentation.

LaTeX 

Easily human readable LaTeX format suitable for printing in manuals.

Member Function Documentation

◆ memory_consumption()

std::size_t Patterns::PatternBase::memory_consumption ( ) const
virtualinherited

Determine an estimate for the memory consumption (in bytes) of this object. To avoid unnecessary overhead, we do not force derived classes to provide this function as a virtual overloaded one, but rather try to cast the present object to one of the known derived classes and if that fails then take the size of this base class instead and add 32 byte (this value is arbitrary, it should account for virtual function tables, and some possible data elements). Since there are usually not many thousands of objects of this type around, and since the memory_consumption mechanism is used to find out where memory in the range of many megabytes is, this seems like a reasonable approximation.

On the other hand, if you know that your class deviates from this assumption significantly, you can still overload this function.

Reimplemented in Patterns::Selection, Patterns::List, Patterns::Map, Patterns::Tuple, and Patterns::MultipleSelection.
