Detailed Description

ElggMetadata.

This class describes metadata that can be attached to an \ElggEntity. It is rare that a plugin developer needs to use this API for metadata. Almost all interaction with metadata occurs through the methods of \ElggEntity. See its __set(), __get(), and setMetadata() methods.
