    Public Member Functions

     StepData_ESDescr (const char *const namename)
     Creates an ESDescr with a type name.
    void SetNbFields (const int nb)
     Sets a new count of fields Each one is described by a PDescr.
    void SetField (const int numnum, const char *const namename, const occ::handle< StepData_PDescr > &descr)
     Sets a PDescr to describe a field A Field is designated by its rank and name.
    void SetBase (const occ::handle< StepData_ESDescr > &base)
     Sets an ESDescr as based on another one Hence, if there are inherited fields, the derived ESDescr cumulates all them, while the base just records its own ones.
    void SetSuper (const occ::handle< StepData_ESDescr > &super)
     Sets an ESDescr as "super-type". Applies an a base (non derived) ESDescr.
    const char * TypeName () const
     Returns the type name given at creation time.
    const TCollection_AsciiStringStepType () const
     Returns the type name as an AsciiString.
    occ::handle< StepData_ESDescrBase () const
     Returns the basic ESDescr, null if <me> is not derived.
    occ::handle< StepData_ESDescrSuper () const
     Returns the super-type ESDescr, null if <me> is root.

     Tells if <me> is sub-type of (or equal to) another one.
    int NbFields () const
     Returns the count of fields.

     Returns the PDescr for the field named <name> (or Null).
    bool Matches (const char *const steptype) const override
     Tells if a ESDescr matches a step type : exact or super type.
    bool IsComplex () const override
     Returns False.
    occ::handle< StepData_DescribedNewEntity () const override
     Creates a described entity (i.e. a simple one).
    Public Member Functions inherited from Standard_Transient
     Standard_Transient ()
     Empty constructor.
     Standard_Transient (const Standard_Transient &)
     Copy constructor – does nothing.
    Standard_Transientoperator= (const Standard_Transient &)
     Assignment operator, needed to avoid copying reference counter.
    virtual ~Standard_Transient ()=default
     Destructor must be virtual.
    virtual const opencascade::handle< Standard_Type > & DynamicType () const
     Returns a type descriptor about this object.
    bool IsInstance (const opencascade::handle< Standard_Type > &theType) const
     Returns a true value if this is an instance of Type.
    bool IsInstance (const char *const theTypeName) const
     Returns a true value if this is an instance of TypeName.
    bool IsKind (const opencascade::handle< Standard_Type > &theType) const
     Returns true if this is an instance of Type or an instance of any class that inherits from Type. Note that multiple inheritance is not supported by OCCT RTTI mechanism.
    bool IsKind (const char *const theTypeName) const
     Returns true if this is an instance of TypeName or an instance of any class that inherits from TypeName. Note that multiple inheritance is not supported by OCCT RTTI mechanism.
    Standard_TransientThis () const
     Returns non-const pointer to this object (like const_cast). For protection against creating handle to objects allocated in stack or call from constructor, it will raise exception Standard_ProgramError if reference counter is zero.
    int GetRefCount () const noexcept
     Get the reference counter of this object.
    void IncrementRefCounter () noexcept
     Increments the reference counter of this object. Uses relaxed memory ordering since incrementing only requires atomicity, not synchronization with other memory operations.
    int DecrementRefCounter () noexcept
     Decrements the reference counter of this object; returns the decremented value. Uses release ordering for the decrement to ensure all writes to the object are visible before the count reaches zero. An acquire fence is added only when the count reaches zero, ensuring proper synchronization before deletion. This is more efficient than using acq_rel for every decrement.
    virtual void Delete () const
     Memory deallocator for transient classes.

    Additional Inherited Members

    typedef void base_type
     Returns a type descriptor about this object.
    static constexpr const char * get_type_name ()
     Returns a type descriptor about this object.
    static const opencascade::handle< Standard_Type > & get_type_descriptor ()
     Returns type descriptor of Standard_Transient class.
