class AllConnected from IFGraph inherits GraphContent
|
|
|
|
---Purpose : this class gives content of the CONNECTED COMPONANT(S)
|
|
-- which include specific Entity(ies)
|
|
|
|
uses Transient, EntityIterator, Graph
|
|
|
|
is
|
|
|
|
Create (agraph : Graph) returns AllConnected;
|
|
---Purpose : creates an AllConnected from a graph, empty ready to be filled
|
|
|
|
Create (agraph : Graph; ent : any Transient)
|
|
returns AllConnected;
|
|
---Purpose : creates an AllConnected which memorizes Entities Connected to
|
|
-- a given one, at any level : that is, itself, all Entities
|
|
-- Shared by it and Sharing it, and so on.
|
|
-- In other terms, this is the content of the CONNECTED COMPONANT
|
|
-- which include a specific Entity
|
|
|
|
GetFromEntity (me : in out; ent : any Transient);
|
|
---Purpose : adds an entity and its Connected ones to the list (allows to
|
|
-- cumulate all Entities Connected by some ones)
|
|
-- Note that if "ent" is in the already computed list,, no entity
|
|
-- will be added, but if "ent" is not already in the list, a new
|
|
-- Connected Componant will be cumulated
|
|
|
|
ResetData (me : in out);
|
|
---Purpose : Allows to restart on a new data set
|
|
|
|
-- -- Results -- --
|
|
-- More-Next-Value give all entities noted in Connected Componant,
|
|
-- including the entities given for construction or to GetFromEntity
|
|
|
|
Evaluate (me : in out) is redefined;
|
|
---Purpose : does the specific evaluation (Connected entities atall levels)
