OFunction - getId()
Retrieves Record ID for the function.
Internally, OrientDB stores functions as records on the database, which you can in turn query and operate on with normal OrientDB SQL statements, rather than through dedicated syntax like
CREATE FUNCTION. This means that each function you create on your database has its own dedicated Record ID. Using this method, you can retrieve this Record ID from the function.
This method returns an
ORID instance that corresponds to the function Record ID.
