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

|
|
---Purpose : adds a list of entities (as an iterator) with shared ones

Evaluate (me : in out) is redefined;
|
|
---Purpose : Evaluates external sources of a set of entities
