Class UML 2.4.1::Interface
Description:
Since an interface specifies conformance characteristics, it does not own
detailed behavior specifications. Instead, interfaces may own a protocol
state machine that specifies event sequences and pre/post conditions for
the operations and receptions described by the interface.Interfaces may
include receptions (in addition to operations).An interface is a kind of
classifier that represents a declaration of a set of coherent public features
and obligations. An interface specifies a contract; any instance of a classifier
that realizes the interface must fulfill that contract. The obligations
that may be associated with an interface are in the form of various kinds
of constraints (such as pre- and post-conditions) or protocol specifications,
which may impose ordering restrictions on interactions through the interface.
