Header:

#include <UnigineImport.h>

This class is used to manage import processors. An import processor is a module that saves objects generated by an importer on the basis of metadata on the whole scene or some of its components to files in UNIGINE native format and performs auxiliary operations during the import process (data preparation, file management, etc.). You can use a set of different processors for each scene component or a single processor for all of them. There are also two specific types of processors:

Pre-processors - perform additional operations with scene metadata prior to generation of UNIGINE's objects.
Post-processors - perform additional operations with files generated in the process of import (e.g. copying files to other folders, adding files to packages, etc.).

NoticeThis is a base class for all import processors. Your custom import processor class must be inherited from it.

You can override one (or all) onProcess*() methods to define the types of components to be processed by it, these overridden methods will be called by the importer when corresponding import operations are performed.

Notice

For pre- and post-processors only the onProcessScene() method is to be overridden.
