Inheritance diagram for FileFormatInterface:

Detailed Description

FileFormatInterface allows to implement and register file formats with its detection algorithm. The FileFormats registry allows to register any format (e.g. FileFormats::Browsable, FileFormats::ImageJpg...).

Detect()

MAXON_METHOD Result<Bool> Detect	(	const Url &	url,
		const InputStreamRef &	probeStream
	)		const

For implementations to check if a given url/stream supports this file format. You should never call this function directly. It's triggered by FileFormatDetectionInterface::Detect()/DetectAll().

Parameters

[in]	url	Url to check.
[in]	probeStream	Optional parameter that allows to read content in case that the url is a file. This stream is not a plain file stream but wraps a memory cache stream which allows to seek and read already loaded data without overhead.

Returns

Returns true if the url/stream fits to this file format implementation.
