Detailed Description

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.

◆ GetFileFormat()

MAXON_METHOD const FileFormat& GetFileFormat ( ) const

Returns the FileFormat which is handled by this FileFormatHandler.

◆ GetHandlerType()

MAXON_METHOD Result<DataType> GetHandlerType ( ) const

Returns the datatype of the reference class of the handler returned by CreateHandler().

◆ CreateHandler() [1/2]

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".

Parameters

[in] url Url to be used with this handler.

◆ CreateHandler() [2/2]

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".

Parameters

[in] url Url to be used with this handler.

Template Parameters

HANDLER Reference class to be expected with the result of CreateHandler.

◆ GetDependends()

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().
