Detailed Description

This interface allows to detect files with a file cache to prevent frequently open file io operations. Used together with DragAndDropHandlerInterface to optimize d&d. e.g. FileFormatDetectionCacheRef fileFormatCacheRef = dndHandlerRef.GetFileDetectionCache() iferr_return; ifnoerr (isTrue = fileFormatCacheRef.DetectFile<MediaInputRef>(url, FILEFORMATDETECTIONFLAGS::NONE)) { if (isTrue) { isMediaSessionUrl |= isTrue; break; } } ifnoerr (isTrue = fileFormatCacheRef.DetectFile<nodes::NodeSystem>(url, FILEFORMATDETECTIONFLAGS::NONE)) { if (isTrue) { isNodeAsset |= isTrue; break; } }

◆ MAXON_INTERFACE()

MAXON_INTERFACE	(	FileFormatDetectionCacheInterface	,
		MAXON_REFERENCE_NORMAL	,
		"net.maxon.interface.fileformatdetectioncacheinterface"	,
		MAXON_IMPLEMENTATION_MODULE("net.maxon.kernel")
	)

◆ DetectFile() [1/3]

MAXON_METHOD Result<Bool> DetectFile	(	const Url &	url,
		FILEFORMATDETECTIONFLAGS	flags,
		const Block< const DataType > &	limitDetection
	)

Checks if a file supports a given file format.

Parameters

[in]	url	Url to detect.
[in]	flags	See FILEFORMATDETECTIONFLAGS.
[in]	limitDetection	Datatype to limit the detection e.g. MediaInputRef, nodes::NodeSystem.

Returns: OK on success.

◆ DetectFile() [2/3]

MAXON_WARN_UNUSED MAXON_FUNCTION Result<Bool> DetectFile	(	const Url &	url,
		FILEFORMATDETECTIONFLAGS	flags
	)

Checks if a file supports a given file format. Helper function to simplify usage e.g. DetectFile<MediaInputRef>().
