23 | class ExternalSources from IFGraph inherits GraphContent |
24 | |
25 | ---Purpose : this class gives entities which are Source of entities of |
26 | -- a sub-part, but are not contained by this sub-part |
27 | |
28 | uses Transient, EntityIterator, Graph |
29 | |
30 | is |
31 | |
32 | Create (agraph : Graph) returns ExternalSources; |
33 | ---Purpose : creates empty ExternalSources, ready to work |
34 | |
35 | GetFromEntity (me : in out; ent : any Transient); |
36 | ---Purpose : adds an entity and its shared ones to the list |
37 | |
38 | GetFromIter (me : in out; iter : EntityIterator); |
39 | ---Purpose : adds a list of entities (as an iterator) with shared ones |
40 | |
41 | ResetData (me : in out); |
42 | ---Purpose : Allows to restart on a new data set |
43 | |
44 | -- -- Results -- -- |
45 | -- More-Next-Value give External Source entities |
46 | |
47 | Evaluate (me : in out) is redefined; |
48 | ---Purpose : Evaluates external sources of a set of entities |
49 | |
50 | IsEmpty(me : in out) returns Boolean; |
51 | ---Purpose : Returns True if no External Source are found |
52 | -- It means that we have a "root" set |
