Member Function Documentation

template<class Domain>

virtual RefPtr<Domain> CreatorBase< Domain >::create

(

)

[pure virtual]

Actually create the object, e.g.

load it from disk.

Implemented in Creator< RefType >.

template<class Domain>

virtual const type_info& CreatorBase< Domain >::getType

(

)

[pure virtual]

Query the associated value type of this creator object.

This type information can possibly be determined without actually loading any data. Whether or not this is the case is up to the implementation of the child class.

Implemented in Creator< RefType >.

template<class Domain>

virtual bool CreatorBase< Domain >::request

(

const RefPtr< Result > &

)

[inline, virtual]

Asynchron mode: Hm.

Data seem not to be available, i.e. the create() function return a null ptr. So, request creating them. Returns false if that is not possible. If create() returned false, and the requestCreation() as well, then we have a real problem.
