    IFSelect_GeneralModifier Class Referenceabstract

    This class gives a frame for Actions which modify the effect of a Dispatch, i.e. : By Selections and Dispatches, an original Model can be split into one or more "target" Models : these Models contain Entities copied from the original one (that is, a part of it). Basically, these dispatched Entities are copied as identical to their original counterparts. Also the copied Models reproduce the Header of the original one. More...

    bool MayChangeGraph () const
     Returns True if this modifier may change the graph of dependences (acknowledged at creation time).
    void SetDispatch (const occ::handle< IFSelect_Dispatch > &disp)
     Attaches to a Dispatch. If <disp> is Null, Resets it (to apply the Modifier on every Dispatch).
    occ::handle< IFSelect_DispatchDispatch () const
     Returns the Dispatch to be matched, Null if not set.
    bool Applies (const occ::handle< IFSelect_Dispatch > &disp) const
     Returns True if a Model obtained from the Dispatch <disp> is to be treated (apart from the Selection criterium) If Dispatch(me) is Null, returns True. Else, checks <disp>.
    void SetSelection (const occ::handle< IFSelect_Selection > &sel)
     Sets a Selection : a Model is treated if it contains one or more Entities designated by the Selection.
    void ResetSelection ()
     Resets the Selection : this criterium is not longer active.
    bool HasSelection () const
     Returns True if a Selection is set as an additional criterium.

     Returns the Selection, or a Null Handle if not set.

    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.

    Detailed Description

    This class gives a frame for Actions which modify the effect of a Dispatch, i.e. : By Selections and Dispatches, an original Model can be split into one or more "target" Models : these Models contain Entities copied from the original one (that is, a part of it). Basically, these dispatched Entities are copied as identical to their original counterparts. Also the copied Models reproduce the Header of the original one.

    Modifiers allow to change this copied content : this is the way to be used for any kind of alterations, adaptations ... They are exploited by a ModelCopier, which firstly performs the copy operation described by Dispatches, then invokes the Modifiers to work on the result.

    Each GeneralModifier can be attached to :

    • all the Models produced
    • a Dispatch (it will be applied to all the Models obtained from this Dispatch) designated by its Ident in a ShareOut
    • in addition, to a Selection (facultative) : this adds a criterium, the Modifier is invoked on a produced Model only if this Model contains an Entity copied from one of the Entities designated by this Selection. (for special Modifiers from IFAdapt, while they must work on definite Entities, this Selection is mandatory to run)

    Remark : this class has no action attached, it only provides a frame to work on criteria. Then, sub-classes will define their kind of action, which can be applied at a precise step of the production of a File : see Modifier, and in the package IFAdapt, EntityModifier and EntityCopier

    Constructor & Destructor Documentation

    ◆ IFSelect_GeneralModifier()

    IFSelect_GeneralModifier::IFSelect_GeneralModifier ( const bool maychangegraph)
    protected

    Sets the Modifier criteria to default Values (i.e. "always applies") <maychangegraph> must be provided at creation time, to :

    • False if this GeneralModifier surely lets the graph of dependencies unchanged (NO edition of any reference, BUT also NO entity added or replaced or removed)
    • True if there is a possibility of changing the graph of dependencies when this modifier is applied

    Member Function Documentation

    ◆ Applies()

    bool IFSelect_GeneralModifier::Applies ( const occ::handle< IFSelect_Dispatch > & disp) const

    Returns True if a Model obtained from the Dispatch <disp> is to be treated (apart from the Selection criterium) If Dispatch(me) is Null, returns True. Else, checks <disp>.

    occ::handle< IFSelect_Dispatch > IFSelect_GeneralModifier::Dispatch ( ) const

    Returns the Dispatch to be matched, Null if not set.

    ◆ HasSelection()

    bool IFSelect_GeneralModifier::HasSelection ( ) const

    Returns True if a Selection is set as an additional criterium.

    ◆ Label()

    ◆ MayChangeGraph()

    bool IFSelect_GeneralModifier::MayChangeGraph ( ) const

    Returns True if this modifier may change the graph of dependences (acknowledged at creation time).

    ◆ ResetSelection()

    void IFSelect_GeneralModifier::ResetSelection ( )

    Resets the Selection : this criterium is not longer active.

    ◆ Selection()

    occ::handle< IFSelect_Selection > IFSelect_GeneralModifier::Selection ( ) const

    Returns the Selection, or a Null Handle if not set.

    ◆ SetDispatch()

    void IFSelect_GeneralModifier::SetDispatch ( const occ::handle< IFSelect_Dispatch > & disp)

    Attaches to a Dispatch. If <disp> is Null, Resets it (to apply the Modifier on every Dispatch).

    ◆ SetSelection()

    void IFSelect_GeneralModifier::SetSelection ( const occ::handle< IFSelect_Selection > & sel)

    Sets a Selection : a Model is treated if it contains one or more Entities designated by the Selection.
