class Compare from IFGraph inherits GraphContent
---Purpose : this class evaluates effect of two compared sub-parts :
-- cumulation (union), common part (intersection-overlapping)
-- part specific to first sub-part or to the second one
-- Results are kept in a Graph, several question can be set
-- Basic Iteration gives Cumulation (union)
uses Transient, EntityIterator, Graph
is
Create (agraph : Graph) returns Compare;
---Purpose : creates empty Compare, ready to work
GetFromEntity (me : in out; ent : any Transient; first : Boolean);
---Purpose : adds an entity and its shared ones to the list :
-- first True means adds to the first sub-list, else to the 2nd
GetFromIter (me : in out; iter : EntityIterator; first : Boolean);
---Purpose : adds a list of entities (as an iterator) as such, that is,
-- their shared entities are not considered (use AllShared to
-- have them)
-- first True means adds to the first sub-list, else to the 2nd
Merge (me : in out);
---Purpose : merges the second list into the first one, hence the second
-- list is empty
RemoveSecond (me : in out);
---Purpose : Removes the contents of second list
KeepCommon (me : in out);
---Purpose : Keeps only Common part, sets it as First list and clears
-- second list
ResetData (me : in out);
---Purpose : Allows to restart on a new data set
-- -- Results -- --
-- More-Next-Value-Entity give all entities taken into the Cumulation
-- other informations are provided, as EntityIterator : hence they
-- are available for other evaluations
Evaluate (me : in out) is redefined;
---Purpose : Recomputes result of comparing to sub-parts
Common (me) returns EntityIterator;
---Purpose : returns entities common to the both parts
FirstOnly (me) returns EntityIterator;
---Purpose : returns entities which are exclusively in the first list
SecondOnly (me) returns EntityIterator;
---Purpose : returns entities which are exclusively in the second part
