Public Member Functions inherited from rdf::BaseElement
	BaseElement (const QString &id=QString())
	This class keeps an ID to keep track of transformed elements during a processing chain. You can e.g. generate Pixel elements from MserBlobs. After filtering, processing etc. you can map back to the (pixel accurate) MserBlob using this ID. More...

void	setId (const QString &id)
	Sets the (preferably unique) ID. If no ID is set, a unqiue ID is generated and assigned. More...

QString	id () const
	Returns the elment's id. More...
