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 :

Public Member Functions | |
Standard_Boolean | MayChangeGraph () const |
Returns True if this modifier may change the graph of dependences (aknowledged at creation time) | |
void | SetDispatch (const Handle< IFSelect_Dispatch > &disp) |
Attaches to a Dispatch. If <disp> is Null, Resets it (to apply the Modifier on every Dispatch) | |
Handle_IFSelect_Dispatch | Dispatch () const |
Returns the Dispatch to be matched, Null if not set | |
Standard_Boolean | 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> | |
void | SetSelection (const 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 | |
Standard_Boolean | HasSelection () const |
Returns True if a Selection is set as an additionnal criterium | |
Handle_IFSelect_Selection | Selection () const |
Returns the Selection, or a Null Handle if not set | |
virtual TCollection_AsciiString | Label () const =0 |
Returns a short text which defines the operation performed | |
Protected Member Functions | |
IFSelect_GeneralModifier (const Standard_Boolean maychangegraph) | |
Sets the Modifier criteria to default Values (i.e. "always applies") <maychangegraph> must be provided at creation time, to : |
- all the Models produced <br> - a Dispatch (it will be applied to all the Models obtained <br> from this Dispatch) designated by its Ident in a ShareOut <br> - in addition, to a Selection (facultative) : this adds a <br> criterium, the Modifier is invoked on a produced Model only <br> if this Model contains an Entity copied from one of the <br> Entities designated by this Selection. <br> (for special Modifiers from IFAdapt, while they must work on <br> definite Entities, this Selection is mandatory to run) <br>
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
