class Tool from STEPConstruct
---Purpose: Provides basic functionalities for tools which are intended
-- for encoding/decoding specific STEP constructs
--
-- It is initialized by WorkSession and allows easy access to
-- its fields and internal data such as Model, TP and FP
--
-- NOTE: Call to method Graph() with True (or for a first time,
-- if you have updated the model since last computation of model)
-- can take a time, so it is recommended to avoid creation of
-- this (and derived) tool multiple times
uses
WorkSession from XSControl,
InterfaceModel from Interface,
Graph from Interface,
HGraph from Interface,
FinderProcess from Transfer,
TransientProcess from Transfer
is
Create returns Tool;
---Purpose: Creates an empty tool
Create (WS: WorkSession from XSControl) returns Tool;
---Purpose: Creates a tool and loads it with worksession
SetWS (me: in out; WS: WorkSession from XSControl)
returns Boolean is protected;
---Purpose: Load worksession; returns True if succeeded
-- Returns False if either FinderProcess of TransientProcess
-- cannot be obtained or are Null
WS (me) returns WorkSession from XSControl;
---Purpose: Returns currently loaded WorkSession
---C++: return const &
---C++: inline
Model (me) returns InterfaceModel from Interface;
---Purpose: Returns current model (Null if not loaded)
---C++: inline
Graph (me; recompute: Boolean = Standard_False) returns Graph from Interface;
---Purpose: Returns current graph (recomputing if necessary)
---C++: return const &
---C++: inline
TransientProcess (me) returns TransientProcess from Transfer;
---Purpose: Returns TransientProcess (reading; Null if not loaded)
---C++: return const &
---C++: inline
FinderProcess (me) returns FinderProcess from Transfer;
---Purpose: Returns FinderProcess (writing; Null if not loaded)
---C++: return const &
---C++: inline
fields
myWS : WorkSession from XSControl;
myFinderProcess: FinderProcess from Transfer;
myTransientProcess: TransientProcess from Transfer;
myHGraph : HGraph from Interface; -- for optimization (no recomutings)
