Detailed Description
A SessionDumper is called by SessionFile. It takes into account a set of classes (such as Selections, Dispatches ...). SessionFile writes the Type (as defined by cdl) of each Item and its general Parameters. It manages the names of the Items.
A SessionDumper must be able to Write the Parameters which are own of each Item it takes into account, given its Class, then to Recognize the Type and Read its Own Parameters to create an Item of this Type with these own Parameters.
Then, there must be defined one sub-type of SessionDumper per consistent set of classes (e.g. a package).
By Own Parameters, understand Parameters given at Creation Time if there are, or specific of a given class, apart from those defined at superclass levels (e.g. Final Selection for a Dispatch, Input Selection for a SelectExtract or SelectDeduct, Direct Status for a SelectExtract, etc...).
The Parameters are those stored in a WorkSession, they can be of Types : IntParam, HAsciiString (for TextParam), Selection, Dispatch.
SessionDumpers are organized in a Library which is used by SessionFile. They are put at Creation Time in this Library.

Returns the First item of the Library of Dumper. The Next ones are then obtained by Next on the returned items.
| Handle< IFSelect_SessionDumper > IFSelect_SessionDumper::Next | ( | ) | const |
Returns the Next SesionDumper in the Library. Returns a Null Handle at the End.

Recognizes a Type (given as <type>) then Creates an Item of this Type with the Own Parameter, as required. Returns True if it has recognized the Type (in this case, it is assumed to have created the Item, returned as ), False else : in that case, SessionFile will try another SessionDumper in the Library. ReadOwn can use these methods from SessionFile to access Own Parameters : NbOwnParams, IsVoid, IsText, TextValue, ItemValue.
Implemented in IFSelect_BasicDumper, and IGESSelect_Dumper.

pure virtual |
Writes the Own Parameters of a given Item, if it forecast to manage its Type. Returns True if it has recognized the Type of the Item (in this case, it is assumed to have written the Own Parameters if there are some), False else : in that case, SessionFile will try another SessionDumper in the Library. WriteOwn can use these methods from SessionFile : SendVoid, SendItem, SendText, and if necessary, WorkSession.
Implemented in IFSelect_BasicDumper, and IGESSelect_Dumper.
