Detailed Description

template<typename Base, typename... Args>
class ryujin::Library< Base, Args >

A registry of creator functions for the abstract base class Base. A creator constructs an object of a class derived from Base from the arguments Args.

Library has only static members and is never constructed. One registry exists per instance: Library<Geometry<2>, const std::string &> and Library<Geometry<3>, const std::string &> are separate registries.

Entries are not keyed by name when they are added. The name of an entry is the name() of the object that it constructs: create() constructs all entries and throws if two of them share a name.

The registry starts with the built-in entries returned by defaults(), which is called when the registry is first used. add() appends further entries, at any time; an entry added after a call to create() is seen by every subsequent call. Objects are created in the order of registration.

A client can add its own entries with add(), for example in main() or in the constructor of an object at namespace scope.

names()

std::vector< std::string > ryujin::Library< Base, Args >::names ( Args...  args )

static

Return the names of the objects that create() constructs, in the same order.

Definition at line 168 of file library.h.

selection()

template<typename Base , typename... Args>

dealii::Patterns::Selection ryujin::Library< Base, Args >::selection ( const std::vector< std::unique_ptr< Base > > &  objects )

static

Return a dealii::Patterns::Selection of the names of the given objects, as returned by create(). It is the pattern of the run time parameter that selects one of the objects by name.

select()

template<typename Base , typename... Args>

Base & ryujin::Library< Base, Args >::select ( const std::vector< std::unique_ptr< Base > > &  objects, const std::string &  name  )

static

Return the object of the given objects, as returned by create(), whose name() is name. Throws if there is none.
