// CLASS DESCRIPTION (MPxFileTranslator)
|
|
//
|
|
// This class provides a base class from which one derives in order to
|
|
// implement Maya "File Translator Plug-Ins." A file translator plug-in
|
|
// allows Maya to read or write 3rd party file formats.
|
|
//
|
|
// The identifyFile method is called whenever Maya's file save or restore
|
|
// dialogs are run, and identifyFile uses the filename and first few bytes
|
|
// of the file to determine whether it is of a type supported by the
|
|
// translator. If it is, then Maya will display the file with the "name"
|
|
// and "icon" specified as arguments to MFnPlugin::registerFileTranslator.
|
|
//
|
|
// If an attempt is made to read the file, the "reader" method in the
|
|
// derived class is called, if an attempt is made to write the file, the
|
|
// "writer" method is called.
