package STEPConstruct
---Purpose: Defines tools for creation and investigation STEP constructs
-- used for representing various kinds of data, such as product and
-- assembly structure, unit contexts, associated information
-- The creation of these structures is made according to currently
-- active schema (AP203 or AP214 CD2 or DIS)
-- This is taken from parameter write.step.schema
uses

is
class Tool;
---Purpose: Basic class providing general features
class UnitContext;
---Purpose: Create and investigate context of units and uncertanties
class Part;
---Purpose: Create and investigate data associated with parts (product etc.)
class Assembly;
---Purpose: Create and check assembly data structures
class Styles;
---Purpose: Create and investigate STEP constructs for styles (mostly colors)
class ValidationProps;
---Purpose: Create and investigate STEP constructs for validation properties
class ExternRefs;
---Purpose: Work with references to external documents
class AP203Context;
---Purpose: maintains context specific to AP203
class ContextTool;
---Purpose: Maintains global context tool for writing

class DataMapOfAsciiStringTransient instantiates
DataMap from TCollection (AsciiString from TCollection,
Transient from Standard,
AsciiString from TCollection);
class PointHasher;
class DataMapOfPointTransient instantiates
DataMap from TCollection (Pnt from gp,
Transient,
PointHasher from STEPConstruct);
FindEntity (FinderProcess: FinderProcess from Transfer; Shape: Shape from TopoDS)
returns RepresentationItem from StepRepr;
---Purpose: Returns STEP entity of the (sub)type of RepresentationItem
-- which is a result of the tranalation of the Shape, or Null if
-- no result is recorded
FindEntity (FinderProcess: FinderProcess from Transfer; Shape: Shape from TopoDS;
Loc: out Location from TopLoc)
returns RepresentationItem from StepRepr;
---Purpose: The same as above, but in the case if item not found, repeats
-- search on the same shape without location. The Loc corresponds to the
-- location with which result is found (either location of the Shape,
-- or Null)
FindShape (TransientProcess: TransientProcess from Transfer; item: RepresentationItem from StepRepr)
returns Shape from TopoDS;
---Purpose: Returns Shape resulting from given STEP entity (Null if not mapped)
FindCDSR (ComponentBinder: Binder from Transfer;
AssemblySDR: ShapeDefinitionRepresentation from StepShape;
ComponentCDSR: out ContextDependentShapeRepresentation from StepShape)
returns Boolean from Standard;
---Purpose: Find CDSR correcponding to the component in the specified assembly
