class SelectSignature from IFSelect inherits SelectExtract
---Purpose : A SelectSignature sorts the Entities on a Signature Matching.
-- The signature to match is given at creation time. Also, the
-- required match is given at creation time : exact (IsEqual) or
-- contains (the Type's Name must contain the criterium Text)
--
-- Remark that no more interpretation is done, it is an
-- alpha-numeric signature : for instance, DynamicType is matched
-- as such, super-types are not considered
--
-- Also, numeric (integer) comparisons are supported : an item
-- can be <val ou <=val or >val or >=val , val being an Integer
--
-- A SelectSignature may also be created from a SignCounter,
-- which then just gives its LastValue as SignatureValue
uses CString, AsciiString from TCollection, Transient,
SequenceOfAsciiString from TColStd, SequenceOfInteger from TColStd,
InterfaceModel, Graph, Signature, SignCounter
is
Create (matcher : Signature;
signtext : CString;
exact : Boolean = Standard_True)
returns mutable SelectSignature;
---Purpose : Creates a SelectSignature with its Signature and its Text to
-- Match.
-- <exact> if True requires exact match,
-- if False requires <signtext> to be contained in the Signature
-- of the entity (default is "exact")
Create (matcher : Signature;
signtext : AsciiString from TCollection;
exact : Boolean = Standard_True)
returns mutable SelectSignature;
---Purpose : As above with an AsciiString
Create (matcher : SignCounter;
signtext : CString;
exact : Boolean = Standard_True)
returns mutable SelectSignature;
---Purpose : Creates a SelectSignature with a Counter, more precisely a
-- SelectSignature. Which is used here to just give a Signature
-- Value (by SignOnly Mode)
-- Matching is the default provided by the class Signature
Signature (me) returns mutable Signature;
---Purpose : Returns the used Signature, then it is possible to access it,
-- modify it as required. Can be null, hence see Counter
Counter (me) returns mutable SignCounter;
---Purpose : Returns the used SignCounter. Can be used as alternative for
-- Signature
SortInGraph (me; rank : Integer; ent : Transient; G : Graph)
returns Boolean is redefined;
---Purpose : Returns True for an Entity (model->Value(num)) of which the
-- signature matches the text given as creation time
-- May also work with a Counter from the Graph
Sort (me; rank : Integer; ent : Transient; model : InterfaceModel)
returns Boolean;
---Purpose : Not called, defined only to remove a deferred method here
SignatureText (me) returns AsciiString from TCollection;
---Purpose : Returns Text used to Sort Entity on its Signature or SignCounter
---C++ : return const &
IsExact (me) returns Boolean;
---Purpose : Returns True if match must be exact
ExtractLabel (me) returns AsciiString from TCollection;
---Purpose : Returns a text defining the criterium.
-- (it refers to the text and exact flag to be matched, and is
-- qualified by the Name provided by the Signature)
