class ActorRead from STEPControl

inherits ActorOfTransientProcess from Transfer

|
|
|
---Purpose : This class performs the transfer of an Entity from

|
-- AP214 and AP203, either Geometric or Topologic.
|
|
--
|
|
-- I.E. for each type of Entity, it invokes the appropriate Tool
|
|
-- then returns the Binder which contains the Result

|
-- representation contexts (i.e. units, which may be different)
|
|
-- Returns True if transformation is computed and is not an identity.
