Detailed Description

General description of Interface Protocols. A Protocol defines a set of Entity types. This class provides also the notion of Active Protocol, as a working context, defined once then exploited by various Tools and Libraries.

It also gives control of type definitions. By default, types are provided by CDL, but specific implementations, or topics like multi-typing, may involve another way

Member Function Documentation

◆ Active()

static Handle< Interface_Protocol > Interface_Protocol::Active ( )
static

Returns the Active Protocol, if defined (else, returns a Null Handle, which means "no defined active protocol")

◆ CaseNumber()

virtual Standard_Integer Interface_Protocol::CaseNumber ( const Handle< Standard_Transient > &  obj) const
virtual

Returns a unique positive CaseNumber for each Recognized Object. By default, recognition is based on Type(1) By default, calls the following one which is deferred.

Reimplemented in StepData_Protocol.

◆ ClearActive()

static void Interface_Protocol::ClearActive ( )
static

Erases the Active Protocol (hence it becomes undefined)

◆ GlobalCheck()

virtual Standard_Boolean Interface_Protocol::GlobalCheck ( const Interface_Graph G,
Handle< Interface_Check > &  ach 
) const
virtual

Evaluates a Global Check for a model (with its Graph) Returns True when done, False if data in model do not apply.

Very specific of each norm, i.e. of each protocol : the uppest level Protocol assumes it, it can call GlobalCheck of its ressources only if it is necessary

Default does nothing, can be redefined

Reimplemented in StepData_FileProtocol.

◆ IsDynamicType()

virtual Standard_Boolean Interface_Protocol::IsDynamicType ( const Handle< Standard_Transient > &  obj) const
virtual

Returns True if type of <obj> is that defined from CDL This is the default but it may change according implementation.

◆ IsSuitableModel()

virtual Standard_Boolean Interface_Protocol::IsSuitableModel ( const Handle< Interface_InterfaceModel > &  model) const
pure virtual

Returns True if <model> is a Model of the considered Norm.

Implemented in StepData_Protocol, and IGESData_Protocol.

◆ IsUnknownEntity()

virtual Standard_Boolean Interface_Protocol::IsUnknownEntity ( const Handle< Standard_Transient > &  ent) const
pure virtual

Returns True if <ent> is an Unknown Entity for the Norm, i.e. same Type as them created by method UnknownEntity (for an Entity out of the Norm, answer can be unpredicable)

Implemented in StepData_Protocol, and IGESData_Protocol.

◆ NbResources()

virtual Standard_Integer Interface_Protocol::NbResources ( ) const
pure virtual

◆ NbTypes()

virtual Standard_Integer Interface_Protocol::NbTypes ( const Handle< Standard_Transient > &  obj) const
virtual

Returns the count of DISTINCT types under which an entity may be processed. Each one is candidate to be recognized by TypeNumber, <obj> is then processed according it By default, returns 1 (the DynamicType)

◆ NewModel()

virtual Handle< Interface_InterfaceModel > Interface_Protocol::NewModel ( ) const
pure virtual

Creates an empty Model of the considered Norm.

Implemented in StepData_Protocol, and IGESData_Protocol.

◆ Resource()

virtual Handle< Interface_Protocol > Interface_Protocol::Resource ( const Standard_Integer  num) const
pure virtual

◆ SetActive()

static void Interface_Protocol::SetActive ( const Handle< Interface_Protocol > &  aprotocol)
static

Sets a given Protocol to be the Active one (for the users of Active, see just above). Applies to every sub-type of Protocol.

◆ Type()

Handle< Standard_Type > Interface_Protocol::Type ( const Handle< Standard_Transient > &  obj,
const Standard_Integer  nt = 1 
) const

Returns a type under which <obj> can be recognized and processed, according its rank in its definition list (see NbTypes). By default, returns DynamicType.

◆ TypeNumber()

virtual Standard_Integer Interface_Protocol::TypeNumber ( const Handle< Standard_Type > &  atype) const
pure virtual

◆ UnknownEntity()

virtual Handle< Standard_Transient > Interface_Protocol::UnknownEntity ( ) const
pure virtual

Creates a new Unknown Entity for the considered Norm.

Implemented in StepData_Protocol, and IGESData_Protocol.
