public RemoteMethodControl setConstraints(MethodConstraints constraints)
RemoteMethodControlgetConstraints method of the copy returns
the identical constraints instance. The original proxy is not modified.
A null value is interpreted as mapping all methods to
empty constraints (one that has no requirements and no preferences).
For any given remote call, the specific client requirements and
preferences to be satisfied are given by the return value of invoking
the getConstraints method of
the specified MethodConstraints instance with a
Method object representing the remote method.
Client constraints placed on a proxy are included in the serialized
state of the proxy. This allows third-party services to be transparent
to the client's needs. For example, if remote object s1
obtains a proxy for remote object s2, and passes that
proxy to remote object s3, expecting s3 to
invoke a remote method on s2, then s1 can
control that call by placing its constraints directly on the proxy
before passing it to s3. If s3 does not
wish to be transparent in this way, then it should explicitly replace
the client constraints on received proxies with whatever constraints
are appropriate to implement its own policy.
