relation - the relation to add to the relation set

Returns:

true if relation is added to the relation set; false if the relation set is unchanged

addAll

Adds all of the relations to the existing relation set. Duplicate entries are ignored.

Parameters:

relations - AccessibleRelation array describing the relation set.

remove

public boolean remove(AccessibleRelation relation)

Removes a relation from the current relation set. If the relation is not in the set, the relation set will be unchanged and the return value will be false. If the relation is in the relation set, it will be removed from the set and the return value will be true.
