PermissionCollection
is the common base class for all collections
that provide a convenient method for determining whether or not a given
permission is implied by any of the permissions present in this collection.
A PermissionCollection
is typically created by using the
newPermissionCollection()
factory method. If the mentioned
method returns null
, then a PermissionCollection
of any type
can be used. If a collection is returned, it must be used for holding several
permissions of the particular type.
Subclasses must be implemented thread save.
