 RWStepAP214_GeneralModule ()
 Creates a GeneralModule

void FillSharedCase (const Standard_Integer CN, const Handle< Standard_Transient > &ent, Interface_EntityIterator &iter) const
 Specific filling of the list of Entities shared by an Entity
<ent>, according to a Case Number <CN> (provided by StepAP214
Protocol).
More...
 
void CheckCase (const Standard_Integer CN, const Handle< Standard_Transient > &ent, const Interface_ShareTool &shares, Handle< Interface_Check > &ach) const
 Specific Checking of an Entity <ent>
More...
 
void CopyCase (const Standard_Integer CN, const Handle< Standard_Transient > &entfrom, const Handle< Standard_Transient > &entto, Interface_CopyTool &TC) const
 Specific Copy ("Deep") from <entfrom> to <entto> (same type)
by using a CopyTool which provides its working Map.
Use method Transferred from CopyTool to work
More...
 
Standard_Boolean NewVoid (const Standard_Integer CN, Handle< Standard_Transient > &ent) const
 Creates a new void entity <entto> according to a Case Number
This entity remains to be filled, by reading from a file or
by copying from another entity of same type (see CopyCase)
More...
 
virtual Standard_Integer CategoryNumber (const Standard_Integer CN, const Handle< Standard_Transient > &ent, const Interface_ShareTool &shares) const
 Returns a category number which characterizes an entity
Category Numbers are managed by the class Category
<shares> can be used to evaluate this number in the context
Default returns 0 which means "unspecified"
More...

Handle_TCollection_HAsciiString 		Name (const Standard_Integer CN, const Handle< Standard_Transient > &ent, const Interface_ShareTool &shares) const
 Returns the name of a STEP Entity according to its type

- Public Member Functions inherited from Interface_GeneralModule
virtual void FillShared (const Handle< Interface_InterfaceModel > &model, const Standard_Integer CN, const Handle< Standard_Transient > &ent, Interface_EntityIterator &iter) const
 Specific filling of the list of Entities shared by an Entity
<ent>, according a Case Number <CN> (formerly computed by
CaseNum), considered in the context of a Model <model>
Default calls FillSharedCase (i.e., ignores the model)
Can be redefined to use the model for working
More...
 
void Share (Interface_EntityIterator &iter, const Handle< Standard_Transient > &shared) const
 Adds an Entity to a Shared List (uses GetOneItem on <iter>)
More...
 
virtual void ListImplied (const Handle< Interface_InterfaceModel > &model, const Standard_Integer CN, const Handle< Standard_Transient > &ent, Interface_EntityIterator &iter) const
 List the Implied References of <ent> considered in the context
of a Model <model> : i.e. the Entities which are Referenced
while not considered as Shared (not copied if <ent> is,
references not renewed by CopyCase but by ImpliedCase, only
if referenced Entities have been Copied too)
FillShared + ListImplied give the complete list of References
Default calls ListImpliedCase (i.e. ignores the model)
Can be redefined to use the model for working
More...
 
virtual void ListImpliedCase (const Standard_Integer CN, const Handle< Standard_Transient > &ent, Interface_EntityIterator &iter) const
 List the Implied References of <ent> (see above)
are Referenced while not considered as Shared (not copied if
<ent> is, references not renewed by CopyCase but by
ImpliedCase, only if referenced Entities have been Copied too)
FillSharedCase + ListImpliedCase give the complete list of
Referenced Entities
The provided default method does nothing (Implied References
are specific of a little amount of Entity Classes).
More...
 
virtual Standard_Boolean CanCopy (const Standard_Integer CN, const Handle< Standard_Transient > &ent) const
 Specific answer to the question "is Copy properly implemented"
Remark that it should be in phase with the implementation of
NewVoid+CopyCase/NewCopyCase
Default returns always False, can be redefined
More...
 
virtual Standard_Boolean Dispatch (const Standard_Integer CN, const Handle< Standard_Transient > &entfrom, Handle< Standard_Transient > &entto, Interface_CopyTool &TC) const
 
 Dispatches an entity <br>
      Returns True if it works by copy, False if it just duplicates <br>
      the starting Handle <br>


Dispatching means producing a new entity, image of the
starting one, in order to be put into a new Model, this Model
being itself the result of a dispatch from an original Model

According to the cases, dispatch can either
More...

 
virtual Standard_Boolean NewCopiedCase (const Standard_Integer CN, const Handle< Standard_Transient > &entfrom, Handle< Standard_Transient > &entto, Interface_CopyTool &TC) const
 Specific operator (create+copy) defaulted to do nothing.
It can be redefined : When it is not possible to work in two
steps (NewVoid then CopyCase). This can occur when there is
no default constructor : hence the result <entto> must be
created with an effective definition.
Remark : if NewCopiedCase is defined, CopyCase has nothing to do
Returns True if it has produced something, false else
More...
 
virtual void RenewImpliedCase (const Standard_Integer CN, const Handle< Standard_Transient > &entfrom, const Handle< Standard_Transient > &entto, const Interface_CopyTool &TC) const
 Specific Copying of Implied References
A Default is provided which does nothing (must current case !)
Already copied references (by CopyFrom) must remain unchanged
Use method Search from CopyTool to work
More...
 
virtual void WhenDeleteCase (const Standard_Integer CN, const Handle< Standard_Transient > &ent, const Standard_Boolean dispatched) const
 
 Prepares an entity to be deleted. What does it mean : <br>
      Basically, any class of entity may define its own destructor <br>
      By default, it does nothing but calling destructors on fields <br>
      With the Memory Manager, it is useless to call destructor, <br>
      it is done automatically when the Handle is nullified(cleared) <br>
      BUT this is ineffective in looping structures (whatever these <br>
      are "Implied" references or not). <br>


THUS : if no loop may appear in definitions, a class which
inherits from TShared is correctly managed by automatic way
BUT if there can be loops (or simply back pointers), they must
be broken, for instance by clearing fields of one of the nodes
The default does nothing, to be redefined if a loop can occur
(Implied generally requires WhenDelete, but other cases can
occur)

Warning : <dispatched> tells if the entity to be deleted has been
produced by Dispatch or not. Hence WhenDelete must be in
coherence with Dispatch
Dispatch can either copy or not.
If it copies the entity, this one should be deleted
If it doesnt (i.e. duplicates the handle) nothing to do

If <dispatch> is False, normal deletion is to be performed
