OutputMapping< DEF >::Resolver Class Reference

#include "steam/mobject/output-mapping.hpp"

Description

template<class DEF>
class steam::mobject::OutputMapping< DEF >::Resolver

transient resolution wrapper to be exposed by map-style access. A Resolver instance represents an output mapping result, yet to be fully resolved. It is created on the stack by the OutputMapping container and internally wired back to the container and the actually stored value (pipe-ID-hash) in the table. Actually retrieving the result value by the client code triggers invocation of the specific resolution functor, embedded in the definition context DEF, which was given when instantiating the OutputMapping template.

Note

depends on the template parameter of the enclosing OutputMapping type!

Member Function Documentation

operator=()

void operator= ( PId  newId2map )

inline

explicitly define a new target ID for this individual mapping

Note

the actually returned result depends on what the configured DEF::output functor will yield when invoked on this ID

Definition at line 184 of file output-mapping.hpp.

operator Target()

operator Target ( )

inline

actually retrieve the target object of the mapping.

This operation is invoked when client code accesses the result of an OutputMapping query.

Returns

result of invoking the configured DEF::output functor

Exceptions

error::Logic

when resolving an unconnected mapping
