IFSelect_WorkLibrary Class Referenceabstract

This class defines the (empty) frame which can be used to
enrich a XSTEP set with new capabilities
In particular, a specific WorkLibrary must give the way for
Reading a File into a Model, and Writing a Model to a File
Thus, it is possible to define several Work Libraries for each
norm, but recommanded to define one general class for each one :
this general class will define the Read and Write methods.

Also a Dump service is provided, it can produce, according the
norm, either a parcel of a file for an entity, or any other
kind of informations relevant for the norm,

virtual Standard_Integer ReadFile (const Standard_CString name, Handle< Interface_InterfaceModel > &model, const Handle< Interface_Protocol > &protocol) const =0
 Gives the way to Read a File and transfer it to a Model
<mod> is the resulting Model, which has to be created by this
method. In case of error, <mod> must be returned Null
Return value is a status with free values.
Simply, 0 is for "Execution OK"
The Protocol can be used to work (e.g. create the Model, read
and recognize the Entities)

virtual Standard_Boolean WriteFile (IFSelect_ContextWrite &ctx) const =0
 
 Gives the way to Write a File from a Model. <br>
      <ctx> contains all necessary informations : the model, the <br>
      protocol, the file name, and the list of File Modifiers to be <br>
      applied, also with restricted list of selected entities for <br>
      each one, if required. <br>
      In return, it brings the produced check-list <br>


The WorkLibrary has to query <applied> to get then run the
ContextWrite by looping like this (example) :
for (numap = 1; numap <= ctx.NbModifiers(); numap ++) {
ctx.SetModifier (numap);
cast ctx.FileModifier() to specific type -> variable filemod
if (!filemod.IsNull()) filemod->Perform (ctx,writer);
filemod then works with ctx. It can, either act on the
model itself (for instance on its header), or iterate
on selected entities (Start/Next/More/Value)
it can call AddFail or AddWarning, as necessary
}

virtual Standard_Boolean CopyModel (const Handle< Interface_InterfaceModel > &original, const Handle< Interface_InterfaceModel > &newmodel, const Interface_EntityIterator &list, Interface_CopyTool &TC) const
 Performs the copy of entities from an original model to a new
one. It must also copy headers if any. Returns True when done.
The provided default works by copying the individual entities
designated in the list, by using the general service class
CopyTool.
It can be redefined for a norm which, either implements Copy
by another way (do not forget to Bind each copied result with
its original entity in TC) and returns True, or does not know
how to copy and returns False

virtual void DumpEntity (const Handle< Interface_InterfaceModel > &model, const Handle< Interface_Protocol > &protocol, const Handle< Standard_Transient > &entity, const Handle< Message_Messenger > &S, const Standard_Integer level) const =0

for each norm. <model> helps to identify, number ... entities.
<level> is to be interpreted for each norm (because of the
formats which can be very different)

const Handle< Interface_InterfaceModel > &  newmodel,
const Interface_EntityIterator list,
Interface_CopyTool TC 
) const
virtual

Performs the copy of entities from an original model to a new
one. It must also copy headers if any. Returns True when done.
The provided default works by copying the individual entities
designated in the list, by using the general service class
CopyTool.
It can be redefined for a norm which, either implements Copy
by another way (do not forget to Bind each copied result with
its original entity in TC) and returns True, or does not know
how to copy and returns False

Reimplemented in StepSelect_WorkLibrary.

const Handle< Standard_Transient > &  entity,
const Handle< Message_Messenger > &  S,
const Standard_Integer  level 
) const
pure virtual

Gives the way of dumping an entity under a form comprehensive
for each norm. <model> helps to identify, number ... entities.
<level> is to be interpreted for each norm (because of the
formats which can be very different)

Implemented in StepSelect_WorkLibrary, and IGESSelect_WorkLibrary.

const Handle< Interface_Protocol > &  protocol,
const Handle< Standard_Transient > &  entity,
const Handle< Message_Messenger > &  S 
) const

Calls deferred DumpEntity with the recorded default level

Standard_CString IFSelect_WorkLibrary::DumpHelp ( const Standard_Integer  level) const

Returns the help line recorded for <level>, or an empty string

void IFSelect_WorkLibrary::DumpLevels ( Standard_Integer def,
Standard_Integer max 
) const

Returns the recorded default and maximum dump levels
If none was recorded, max is returned negative, def as zero

virtual Standard_Integer IFSelect_WorkLibrary::ReadFile ( const Standard_CString  name,
Handle< Interface_InterfaceModel > &  model,
const Handle< Interface_Protocol > &  protocol 
) const
pure virtual

Gives the way to Read a File and transfer it to a Model
<mod> is the resulting Model, which has to be created by this
method. In case of error, <mod> must be returned Null
Return value is a status with free values.
Simply, 0 is for "Execution OK"
The Protocol can be used to work (e.g. create the Model, read
and recognize the Entities)

Implemented in StepSelect_WorkLibrary, and IGESSelect_WorkLibrary.

void IFSelect_WorkLibrary::SetDumpHelp ( const Standard_Integer  level,
const Standard_CString  help 
)

Records a short line of help for a level (0 - max)

void IFSelect_WorkLibrary::SetDumpLevels ( const Standard_Integer  def,
const Standard_Integer  max 
)

Records a default level and a maximum value for level
level for DumpEntity can go between 0 and <max>
default value will be <def>

virtual Standard_Boolean IFSelect_WorkLibrary::WriteFile ( IFSelect_ContextWrite ctx) const
pure virtual

 Gives the way to Write a File from a Model. <br>
      <ctx> contains all necessary informations : the model, the <br>
      protocol, the file name, and the list of File Modifiers to be <br>
      applied, also with restricted list of selected entities for <br>
      each one, if required. <br>
      In return, it brings the produced check-list <br>


The WorkLibrary has to query <applied> to get then run the
ContextWrite by looping like this (example) :
for (numap = 1; numap <= ctx.NbModifiers(); numap ++) {
ctx.SetModifier (numap);
cast ctx.FileModifier() to specific type -> variable filemod

filemod then works with ctx. It can, either act on the
model itself (for instance on its header), or iterate
on selected entities (Start/Next/More/Value)
it can call AddFail or AddWarning, as necessary
