findAll()

QList< int > Digikam::ThumbsDb::findAll

(

)

Returns the thumbnail ids of all thumbnails in the database.

Referenced by Digikam::DatabaseTask::run().

findByCustomIdentifier()

ThumbsDbInfo Digikam::ThumbsDb::findByCustomIdentifier

(

const QString &

id

)

findByFilePath() [1/2]

ThumbsDbInfo Digikam::ThumbsDb::findByFilePath

(

const QString &

path

)

findByFilePath() [2/2]

ThumbsDbInfo Digikam::ThumbsDb::findByFilePath	(	const QString &	path,
		const QString &	uniqueHash
	)

This is findByFilePath with extra security: Pass the uniqueHash which you have. If an entry is found by file path, and the entry is referenced by any uniqueHash, which is different from the given hash, a null info is returned. If uniqueHash is null, equivalent to the simple findByFilePath.
