-class ExternalSources from IFGraph inherits GraphContent
-
- ---Purpose : this class gives entities which are Source of entities of
- -- a sub-part, but are not contained by this sub-part
-
-uses Transient, EntityIterator, Graph
-
-is
-
- Create (agraph : Graph) returns ExternalSources;
- ---Purpose : creates empty ExternalSources, ready to work
-
- GetFromEntity (me : in out; ent : any Transient);
- ---Purpose : adds an entity and its shared ones to the list
-
- GetFromIter (me : in out; iter : EntityIterator);
- ---Purpose : adds a list of entities (as an iterator) with shared ones
-
- ResetData (me : in out);
- ---Purpose : Allows to restart on a new data set
-
- -- -- Results -- --
- -- More-Next-Value give External Source entities
-
- Evaluate (me : in out) is redefined;
- ---Purpose : Evaluates external sources of a set of entities
-
- IsEmpty(me : in out) returns Boolean;
- ---Purpose : Returns True if no External Source are found
- -- It means that we have a "root" set
- -- (performs an Evaluation as necessary)
