23 class WorkSession from XSControl inherits WorkSession from IFSelect
25 ---Purpose : This WorkSession completes the basic one, by adding :
26 -- - use of Controller, with norm selection...
27 -- - management of transfers (both ways) with auxiliary classes
28 -- TransferReader and TransferWriter
29 -- -> these transfers may work with a Context List : its items
30 -- are given by the user, according to the transfer to be
31 -- i.e. it is interpreted by the Actors
32 -- Each item is accessed by a Name
34 uses CString, Transient, DictionaryOfTransient,
35 InterfaceModel, CheckIterator,
36 TransientProcess, FinderProcess,
37 TransferReader, TransferWriter, Controller, Vars, ReturnStatus,
38 Messenger from Message,
43 Create returns mutable WorkSession from XSControl;
45 ClearData (me : mutable; mode : Integer) is redefined;
46 ---Purpose : In addition to basic ClearData, clears Transfer and Management
47 -- for interactive use, for mode = 0,1,2 and over 4
48 -- Plus : mode = 5 to clear Transfers (both ways) only
49 -- mode = 6 to clear enforced results
50 -- mode = 7 to clear transfers, results
55 SelectNorm (me : mutable; normname : CString; profile : CString = "")
57 ---Purpose : Selects a Norm defined by its name.
58 -- A Norm is described and handled by a Controller
59 -- Returns True if done, False if <normname> is unknown
61 -- A Profile may be set too. If no Profile is provided, the
62 -- current Profile for this Norm is taken
63 -- If the asked Profile is not defined for this Norm, it remains
64 -- in current Profile, returned value is True
66 SelectProfile (me : mutable; profile : CString) returns Boolean;
67 ---Purpose : Sets a Profile as current for the current Norm
68 -- Returns True if done, False if <profile> is unknown for this norm
70 -- For more infos on Profile, query the Profile of the Controller
72 SetController (me : mutable; ctl : mutable Controller);
73 ---Purpose : Selects a Norm defined by its Controller itself
75 AdaptNorm (me : mutable) is virtual;
76 ---Purpose : This method is called once a new norm has been successfully
77 -- selected. It can be redefined, default does nothing
79 SelectedNorm (me; rsc : Boolean = Standard_False) returns CString;
80 ---Purpose : Returns the name of the last Selected Norm. If none is
81 -- defined, returns an empty string
82 -- By default, returns the complete name of the norm
83 -- If <rsc> is True, returns the short name used for resource
85 NormAdaptor (me) returns mutable Controller;
86 ---Purpose : Returns the norm controller itself
88 -- Context used for Transfer : it is a DictionaryOfTransient (no control here)
90 Context (me) returns DictionaryOfTransient;
91 ---Purpose : Returns the current Context List, Null if not defined
92 -- The Context is given to the TransientProcess for TransferRead
94 SetAllContext (me : mutable; context : DictionaryOfTransient);
95 ---Purpose : Sets the current Context List, as a whole
96 -- Sets it to the TransferReader
98 ClearContext (me : mutable);
99 ---Purpose : Clears the whole current Context (nullifies it)
101 -- Management and Actions of Transfer (Read) --
102 -- performed by TransferReader
103 -- WorkSession adds some useful accesses
104 -- It is actually oriented to shapes and transient objects
106 PrintTransferStatus (me; num : Integer; wri : Boolean; S : Messenger from Message)
108 ---Purpose : Prints the transfer status of a transferred item, as beeing
109 -- the Mapped n0 <num>, from MapWriter if <wri> is True, or
110 -- from MapReader if <wri> is False
111 -- Returns True when done, False else (i.e. num out of range)
113 InitTransferReader (me : mutable; mode : Integer);
114 ---Purpose : Sets a Transfer Reader, by internal ways, according mode :
115 -- 0 recreates it clear, 1 clears it (does not recreate)
116 -- 2 aligns Roots of TransientProcess from final Results
117 -- 3 aligns final Results from Roots of TransientProcess
118 -- 4 begins a new transfer (by BeginTransfer)
119 -- 5 recreates TransferReader then begins a new transfer
121 SetTransferReader (me : mutable; TR : mutable TransferReader);
122 ---Purpose : Sets a Transfer Reader, which manages transfers on reading
124 TransferReader (me) returns mutable TransferReader;
125 ---Purpose : Returns the Transfer Reader, Null if not set
127 MapReader (me) returns mutable TransientProcess;
128 ---Purpose : Returns the TransientProcess(internal data for TransferReader)
130 SetMapReader (me : mutable; TP : mutable TransientProcess) returns Boolean;
131 ---Purpose : Changes the Map Reader, i.e. considers that the new one
132 -- defines the relevant read results (forgets the former ones)
133 -- Returns True when done, False in case of bad definition, i.e.
134 -- if Model from TP differs from that of Session
136 Result (me; ent : Transient; mode : Integer)
137 returns mutable Transient;
138 ---Purpose : Returns the result attached to a starting entity
139 -- If <mode> = 0, returns Final Result
140 -- If <mode> = 1, considers Last Result
141 -- If <mode> = 2, considers Final, else if absent, Last
142 -- returns it as Transient, if result is not transient returns
144 -- <mode> = 10,11,12 idem but returns the Binder itself
145 -- (if it is not, e.g. Shape, returns the Binder)
146 -- <mode> = 20, returns the ResultFromModel
148 TransferReadOne (me : mutable; ents : Transient) returns Integer;
149 ---Purpose : Commands the transfer of, either one entity, or a list
150 -- I.E. calls the TransferReader after having analysed <ents>
151 -- It is cumulated from the last BeginTransfer
152 -- <ents> is processed by GiveList, hence :
153 -- - <ents> a Selection : its SelectionResult
154 -- - <ents> a HSequenceOfTransient : this list
155 -- - <ents> the Model : in this specific case, all the roots,
156 -- with no cumulation of former transfers (TransferReadRoots)
158 TransferReadRoots (me : mutable) returns Integer;
159 ---Purpose : Commands the transfer of all the root entities of the model
160 -- i.e. calls TransferRoot from the TransferReader with the Graph
161 -- No cumulation with former calls to TransferReadOne
163 -- Other actions : see the class TransferReader
165 -- BeginTransferRead (me : mutable) returns Boolean; and
166 -- RecognizeRead (me : mutable; ent : Transient) see TransferReader
167 -- TransferReadOne (me : mutable; ents : Transient) -> TransferOne/List
168 -- TransferReadRoots (me : mutable) returns Integer;
169 -- TransferReadCheckList (me) returns CheckIterator; -> LastCheckList
170 -- TransferReadCheckOne (me; ent : Transient; level : Integer = 0)
171 -- -> CheckList avec en plus level = -1 (last)
172 -- TransferredReadList (me; ents : Transient; -> CheckedList
173 -- withcheck : Integer = 0; level : Integer = 0) withcheck a change
174 -- TransferReadClear (me : mutable; ents : Transient; level : Integer = 0);
175 -- ShapeResultList (me : mutable) returns HSequenceOfShape from TopTools;
176 -- + rec : Boolean (recorded/last)
179 -- Management of Transfer (Write) --
180 -- It is actually oriented to shapes
182 NewModel (me : mutable) returns mutable InterfaceModel from Interface;
183 ---Purpose : produces and returns a new Model well conditionned
184 -- It is produced by the Norm Controller
185 -- It can be Null (if this function is not implemented)
187 TransferWriter (me) returns mutable TransferWriter;
188 ---Purpose : Returns the Transfer Reader, Null if not set
190 MapWriter (me) returns mutable FinderProcess;
191 ---Purpose : Returns the FinderProcess (internal data for TransferWriter)
193 SetMapWriter (me : mutable; FP : mutable FinderProcess) returns Boolean;
194 ---Purpose : Changes the Map Reader, i.e. considers that the new one
195 -- defines the relevant read results (forgets the former ones)
196 -- Returns True when done, False if <FP> is Null
198 SetModeWriteShape (me : mutable; mode : Integer);
199 ---Purpose : Sets a mode to transfer Shapes from CasCade to entities of the
200 -- current norm, which interprets it (see various Controllers)
201 -- This call form could be later replaced by a more general one
203 ModeWriteShape (me) returns Integer;
204 ---Purpose : Records the current Mode to Write Shapes
206 TransferWriteShape (me : mutable; shape : Shape from TopoDS;
207 compgraph : Boolean = Standard_True)
208 returns ReturnStatus;
209 ---Purpose : Transfers a Shape from CasCade to a model of current norm,
210 -- according to the last call to SetModeWriteShape
211 -- Returns status :Done if OK, Fail if error during transfer,
212 -- Error if transfer badly initialised
214 TransferWriteCheckList (me) returns CheckIterator;
215 ---Purpose : Returns the check-list of last transfer (write)
216 -- It is recorded in the FinderProcess, but it must be bound with
217 -- resulting entities (in the resulting file model) rather than
218 -- with original objects (in fact, their mappers)
221 Vars (me) returns Vars;
223 SetVars (me : mutable; newvars : Vars);
225 ClearBinders (me : mutable);
226 ---Purpose : Clears binders
234 theController : Controller;
235 theTransferRead : TransferReader from XSControl;
236 theTransferWrite : TransferWriter from XSControl;
237 theContext : DictionaryOfTransient;
238 theModeWriteShape : Integer;
