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.

Detailed Description

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,

◆ IFSelect_WorkLibrary()

IFSelect_WorkLibrary::IFSelect_WorkLibrary ( )
protected

Required to initialise fields.

Member Function Documentation

◆ CopyModel()

virtual Standard_Boolean IFSelect_WorkLibrary::CopyModel ( const Handle< Interface_InterfaceModel > &  original,
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.

◆ DumpEntity() [1/2]

virtual void IFSelect_WorkLibrary::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
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.

◆ DumpEntity() [2/2]

void IFSelect_WorkLibrary::DumpEntity ( const Handle< Interface_InterfaceModel > &  model,
const Handle< Interface_Protocol > &  protocol,
const Handle< Standard_Transient > &  entity,
const Handle< Message_Messenger > &  S 
) const

Calls deferred DumpEntity with the recorded default level.

◆ DumpHelp()

Standard_CString IFSelect_WorkLibrary::DumpHelp ( const Standard_Integer  level) const

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

◆ DumpLevels()

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.

◆ ReadFile()

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.

◆ SetDumpHelp()

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

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

◆ SetDumpLevels()

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>

◆ WriteFile()

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

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

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 }

Implemented in StepSelect_WorkLibrary, and IGESSelect_WorkLibrary.
