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 splitted 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...

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 splitted 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 :

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 Standard_Boolean  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()

Standard_Boolean IFSelect_GeneralModifier::Applies ( const 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>

◆ Dispatch()

Handle< IFSelect_Dispatch > IFSelect_GeneralModifier::Dispatch ( ) const

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

◆ HasSelection()

Standard_Boolean IFSelect_GeneralModifier::HasSelection ( ) const

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

◆ Label()

virtual TCollection_AsciiString IFSelect_GeneralModifier::Label ( ) const
pure virtual

◆ MayChangeGraph()

Standard_Boolean IFSelect_GeneralModifier::MayChangeGraph ( ) const

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

◆ ResetSelection()

void IFSelect_GeneralModifier::ResetSelection ( )

Resets the Selection : this criterium is not longer active.

◆ Selection()

Handle< IFSelect_Selection > IFSelect_GeneralModifier::Selection ( ) const

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

◆ SetDispatch()

void IFSelect_GeneralModifier::SetDispatch ( const 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 Handle< IFSelect_Selection > &  sel)

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