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
uses
TransientProcess from Transfer,
Binder from Transfer,
Trsf from gp,
Axis2Placement3d from StepGeom,
Representation from StepRepr,
RepresentationRelationship from StepRepr,
ProductDefinition from StepBasic,
NextAssemblyUsageOccurrence from StepRepr,

is
Create returns mutable ActorRead from STEPControl;
Recognize (me : mutable; start : Transient) returns Boolean is redefined;
Transfer (me : mutable; start : Transient;

returns mutable Binder from Transfer is redefined;
-- calls TransferShape

---Private: unit and uncertainty context management
PrepareUnits (me : mutable; rep: Representation from StepRepr;
TP: mutable TransientProcess from Transfer);
---Purpose: set units and tolerances context by given ShapeRepresentation
ResetUnits (me: mutable);
---Purpose: reset units and tolerances context to default
--- (mm, radians, read.precision.val, etc.)
ComputeTransformation (me: mutable; Origin, Target: Axis2Placement3d from StepGeom;

---Purpose: Computes transformation defined by two axis placements (in MAPPED_ITEM
-- or ITEM_DEFINED_TRANSFORMATION) taking into account their
-- representation contexts (i.e. units, which may be different)
-- Returns True if transformation is computed and is not an identity.

TP : mutable TransientProcess from Transfer;
isManifold : Boolean) returns mutable ShapeBinder from TransferBRep is protected;
---Purpose:Transfers geometric representation item entity such as ManifoldSolidBRep ,...etc

TP : mutable TransientProcess from Transfer) returns mutable ShapeBinder from TransferBRep is protected;
---Purpose:Transfers mapped item
TransferEntity(me: mutable; fs : FaceSurface from StepShape;
TP : mutable TransientProcess from Transfer) returns mutable ShapeBinder from TransferBRep is protected;
---Purpose:Transfers FaceSurface entity
OldWay(me: mutable; start : Transient;

---Purpose:Tranlates file by old way when CDSR are roots . Acts only if "read.step.product_mode" is equal Off.
