#include <fileformat_handler.h>
FileFormatHandlerInterface implements a handler for a specific FileFormat. E.g. two different implementations could offer different loaders for one and the same FileFormat. FileFormat::Zip implements one handler for Directory Browsing (IoBrowseRef) and one for ReadArchiveRef.

| const MAXON_METHOD FileFormat& GetFileFormat | ( | ) | const |
Returns the FileFormat which is handled by this FileFormatHandler.
| MAXON_METHOD Result < DataType > GetHandlerType | ( | ) | const |
Returns the datatype of the reference class of the handler returned by CreateHandler() .
| MAXON_METHOD Result <ObjectRef> CreateHandler | ( | const Url & | url | ) | const |
Creates an ObjectRef which handles the given url with the generic interface. CreateHandler<InterfaceRef>() can be used to get the expected reference in the right format. E.g. FileFormat::Zip implements one handler for Directory Browsing "IoBrowseRef" and one for working with archives "ReadArchiveRef".
| [in] | url | Url to be used with this handler. |
| MAXON_FUNCTION Result <HANDLER> CreateHandler | ( | const Url & | url | ) | const |
Creates an ObjectRef which handles the given url with the specific interface. E.g. FileFormat::Zip implements one handler for Directory Browsing "IoBrowseRef" and one for workign with archives "ReadArchiveRef".
| [in] | url | Url to be used with this handler. |
| HANDLER | Reference class to be expected with the result of CreateHandler. |
| MAXON_METHOD FILEFORMAT_PRIORITY GetDependends | ( | ) | const |
Returns the dependencies of this FileFormatHandler. This allows to give an priority order for a implementation. This function should not be called except from FileFormatDetectionInterface::DetectAll() .
