class UndefinedEntity from StepData inherits TShared
|
|
|
|
---Purpose : Undefined entity specific to Step Interface, in which StepType
|
|
-- is defined at each instance, or is a SubList of another one
|
|
-- Uses an UndefinedContent, that from Interface is suitable.
|
|
-- Also an Entity defined by STEP can be "Complex Type" (see
|
|
-- ANDOR clause in Express).

is

|
|
Create returns mutable UndefinedEntity;
|
|
---Purpose : creates an Unknown entity
|
|
|
|
Create (issub : Boolean) returns mutable UndefinedEntity;
|
|
---Purpose : Creates a SubList of an Unknown entity : it is an Unknown
|
|
-- Entity with no Type, but flagged as "SUB" if issub is True
|
|
|
|
UndefinedContent (me) returns mutable UndefinedContent;
|
|
---Purpose : Returns the UndefinedContent which brings the Parameters
|
|
|
|
|
|
IsSub (me) returns Boolean;
|
|
---Purpose : Returns True if an Unndefined Entity is SubPart of another one
|
|
|
|
Super (me) returns mutable UndefinedEntity;
|
|
---Purpose : Returns the "super-entity" of a sub-part
|
|
|
|
IsComplex (me) returns Boolean;
|
|
---Purpose : Returns True if <me> defines a Multiple Type Entity (see ANDOR)
|
|
|
|
Next (me) returns mutable UndefinedEntity;
|
|
---Purpose : For a Multiple Type Entity, returns the Next "Componant"
|
|
-- For more than two Types, iterative definition (Next->Next...)
|
|
-- Returns a Null Handle for the end of the List
|
|
|
|
|
|
StepType (me) returns CString;
|
|
---Purpose : gives entity type, read from file
|
|
-- For a Complex Type Entity, gives the first Type read, each
|
|
-- "Next" gives its "partial" type
|
|
-- was C++ : return const
|
|
|
|
ReadRecord (me : mutable;
|
|
SR : StepReaderData; num : Integer; ach : in out Check);
|
|
---Purpose : reads data from StepReaderData (i.e. from file), by filling
|
|
-- StepType and parameters stored in the UndefinedContent
|
|
|
|
WriteParams (me; SW : in out StepWriter);
|
|
---Purpose : write data to StepWriter, taken from UndefinedContent
|
|
|
|
GetFromAnother (me : mutable; other : like me;
|
|
TC : in out CopyTool);
|
|
---Purpose : reads another UndefinedEntity from StepData
|
|
|
|
FillShared (me; list : in out EntityIterator from Interface);
|
|
---Purpose : Fills the list of shared entities
