# XSControl_Reader Class Reference

A groundwork to convert a shape to data which complies
with a particular norm. This data can be that of a whole
model or that of a specific list of entities in the model.
You specify the list using a single selection or a
combination of selections. A selection is an operator which
computes a list of entities from a list given in input. To
specify the input, you can use:
- A predefined selection such as "xst-transferrable-roots"
- A filter based on a signature.
A signature is an operator which returns a string from an
entity according to its type.
For example:
- "xst-type" (CDL)
- "iges-level"
- "step-type".
A filter can be based on a signature by giving a value to
be matched by the string returned. For example,
"xst-type(Curve)".
If no list is specified, the selection computes its list of
entities from the whole model. To use this class, you have to
initialize the transfer norm first, as shown in the example below.
Example:
Control_Reader reader;
IFSelect_ReturnStatus status = reader.ReadFile (filename.);
When using IGESControl_Reader or STEPControl_Reader - as the
above example shows - the reader initializes the norm directly.
Note that loading the file only stores the data. It does
not translate this data. Shapes are accumulated by
successive transfers. The last shape is cleared by:
- ClearShapes which allows you to handle a new batch
- TransferRoots which restarts the list of shapes from scratch.

void * | operator new (size_t, void *anAddress)
void * | operator new (size_t size)

Standard_EXPORT | XSControl_Reader ()

Standard_EXPORT Handle_XSControl_WorkSession | WS () const

Standard_EXPORT IFSelect_ReturnStatus | ReadFile (const Standard_CString filename)
| Loads a file and returns the read status Zero for a Model which compies with the Controller .
Standard_EXPORT Handle_Interface_InterfaceModel | Model () const
| Returns the model. It can then be consulted (header, product) .
Standard_EXPORT Handle_TColStd_HSequenceOfTransient | GiveList (const Standard_CString first="", const Standard_CString second="")

Returns a list of entities from the IGES or STEP file
according to the following rules:
- if first and second are empty strings, the whole file is selected.
- if first is an entity number or label, the entity referred to is selected.
- if first is a list of entity numbers/labels separated by commas, the entities referred to are selected,
- if first is the name of a selection in the worksession and second is not defined,
the list contains the standard output for that selection.
- if first is the name of a selection and second is defined, the criterion defined
by second is applied to the result of the first selection.
A selection is an operator which computes a list of entities from a list given in
input according to its type. If no list is specified, the selection computes its
list of entities from the whole model.
A selection can be:
- A predefined selection (xst-transferrable-mode)
- A filter based on a signature
A Signature is an operator which returns a string from an entity according to its type. For example:
- "xst-type" (CDL)
- "iges-level"
- "step-type".
For example, if you wanted to select only the advanced_faces in a STEP file you
would use the following code:
Example
Reader.GiveList("xst-transferrable-roots","step-type(ADVANCED_FACE)");
Warning
If the value given to second is incorrect, it will simply be ignored.
.

Standard_EXPORT Handle_TColStd_HSequenceOfTransient | GiveList (const Standard_CString first, const Handle(Standard_Transient)&ent)
| Computes a List of entities from the model as follows <first> beeing a Selection, <ent> beeing an entity or a list of entities (as a HSequenceOfTransient) : the standard result of this selection applied to this list if <first> is erroneous, a null handle is returned .
virtual Standard_EXPORT Standard_Integer | NbRootsForTransfer ()

Standard_EXPORT Handle_Standard_Transient | RootForTransfer (const Standard_Integer num=1)
| Returns an IGES or STEP root entity for translation. The entity is identified by its rank in a list. .
Standard_EXPORT Standard_Boolean | TransferOneRoot (const Standard_Integer num=1)
| Translates a root identified by the rank num in the model. false is returned if no shape is produced. .
Standard_EXPORT Standard_Boolean | TransferOne (const Standard_Integer num)
| Translates an IGES or STEP entity identified by the rank num in the model. false is returned if no shape is produced. .
Standard_EXPORT Standard_Boolean | TransferEntity (const Handle(Standard_Transient)&start)

Standard_EXPORT Standard_Integer | TransferList (const Handle(TColStd_HSequenceOfTransient)&list)
| Translates a list of entities. Returns the number of IGES or STEP entities that were successfully translated. The list can be produced with GiveList. Warning - This function does not clear the existing output shapes. .
Standard_EXPORT Standard_Integer | TransferRoots ()
| Translates all translatable roots and returns the number of successful translations. Warning - This function clears existing output shapes first. .
Standard_EXPORT void | ClearShapes ()
| Clears the list of shapes that may have accumulated in calls to TransferOne or TransferRoot.C .
Standard_EXPORT Standard_Integer | NbShapes () const
| Returns the number of shapes produced by translation. .
Standard_EXPORT TopoDS_Shape | Shape (const Standard_Integer num=1) const
| Returns the shape resulting from a translation and identified by the rank num. num equals 1 by default. In other words, the first shape resulting from the translation is returned. .
Standard_EXPORT TopoDS_Shape | OneShape () const
| Returns all of the results in a single shape which is: - a null shape if there are no results, - a shape if there is one result, - a compound containing the resulting shapes if there are more than one. .
Standard_EXPORT void | PrintCheckLoad (const Standard_Boolean failsonly, const IFSelect_PrintCount mode) const
| Prints the check list attached to loaded data, on the Standard Trace File (starts at cout) All messages or fails only, according to <failsonly> mode = 0 : per entity, prints messages mode = 1 : per message, just gives count of entities per check mode = 2 : also gives entity numbers .
Standard_EXPORT void | PrintCheckTransfer (const Standard_Boolean failsonly, const IFSelect_PrintCount mode) const
| Displays check results for the last translation of IGES or STEP entities to Open CASCADE entities. Only fail messages are displayed if failsonly is true. All messages are displayed if failsonly is false. mode determines the contents and the order of the messages according to the terms of the IFSelect_PrintCount enumeration. .
Standard_EXPORT void | PrintStatsTransfer (const Standard_Integer what, const Standard_Integer mode=0) const

Displays the statistics for
the last translation. what defines the kind of
statistics that are displayed as follows:
- 0 gives general statistics (number of translated roots,
number of warnings, number of fail messages),
- 1 gives root results,
- 2 gives statistics for all checked entities,
- 3 gives the list of translated entities,
- 4 gives warning and fail messages,
- 5 gives fail messages only.
The use of mode depends on the value of what. If what is 0,
mode is ignored. If what is 1, 2 or 3, mode defines the following:
- 0 lists the numbers of IGES or STEP entities in the respective model
- 1 gives the number, identifier, type and result
type for each IGES or STEP entity and/or its status
(fail, warning, etc.)
- 2 gives maximum information for each IGES or STEP entity (i.e. checks)
- 3 gives the number of entities per type of IGES or STEP entity
- 4 gives the number of IGES or STEP entities per result type and/or status
- 5 gives the number of pairs (IGES or STEP or result type and status)
- 6 gives the number of pairs (IGES or STEP or result type
and status) AND the list of entity numbers in the IGES or STEP model.
If what is 4 or 5, mode defines the warning and fail
messages as follows:
- if mode is 0 all warnings and checks per entity are returned
- if mode is 2 the list of entities per warning is returned.
If mode is not set, only the list of all entities per warning is given.
