A Transformer defines the way an InterfaceModel is transformed
(without sending it to a file).
In order to work, each type of Transformer defines it method
Perform, it can be parametred as needed.
It receives a Model (the data set) as input. It then can :

Public Member Functions | |
virtual Standard_Boolean | Perform (const Interface_Graph &G, const Handle< Interface_Protocol > &protocol, Interface_CheckIterator &checks, Handle< Interface_InterfaceModel > &newmod)=0 |
Performs a Transformation (defined by each sub-class) : <G> gives the input data (especially the starting model) and can be used for queries (by Selections, etc...) <protocol> allows to work with General Services as necessary (it applies to input data) If the change corresponds to a conversion to a new protocol, see also the method ChangeProtocol <checks> stores produced checks messages if any <newmod> gives the result of the transformation : | |
virtual Standard_Boolean | ChangeProtocol (Handle< Interface_Protocol > &newproto) const |
This methods allows to declare that the Protocol applied to the new Model has changed. It applies to the last call to Perform. Returns True if the Protocol has changed, False else. The provided default keeps the starting Protocol. This method should be redefined as required by the effect of Perform. | |
virtual Standard_Boolean | Updated (const Handle< Standard_Transient > &entfrom, Handle< Standard_Transient > &entto) const =0 |
This method allows to know what happened to a starting entity after the last Perform. If <entfrom> (from starting model) has one and only one known item which corresponds in the new produced model, this method must return True and fill the argument <entto>. Else, it returns False. | |
virtual TCollection_AsciiString | Label () const =0 |
Returns a text which defines the way a Transformer works (to identify the transformation it performs) |
