checkConstraints method is
intended to be used by an
InvocationDispatcher to verify
support for constraints.
|Modifier and Type||Method and Description|
Verifies that this instance supports the transport layer aspects of all of the specified requirements (both in general and in the current security context), and returns the requirements that must be at least partially implemented by higher layers in order to fully satisfy all of the specified requirements.
InvocationConstraints checkConstraints(InvocationConstraints constraints) throws UnsupportedConstraintException
For any given constraint, there must be a clear delineation
of which aspects (if any) must be implemented by the transport
layer. This method must not return a constraint (as a
requirement or a preference, directly or as an element of
another constraint) unless this instance can implement all of
those aspects. Also, this method must not return a constraint
for which all aspects must be implemented by the transport
layer. Most of the constraints in the
net.jini.core.constraint package must be fully implemented by
the transport layer and thus must not be returned by this
method; the one exception is
Integrity, for which the
transport layer is responsible for the data integrity aspect
and higher layers are responsible for the code integrity
ConstraintAlternatives in the specified
constraints, this method should only return a corresponding
constraint if all of the alternatives supported by this
instance need to be at least partially implemented by higher
layers in order to be fully satisfied.
The constraints passed to this method may include constraints based on relative time.
constraints- the constraints that must be supported
UnsupportedConstraintException- if the transport layer aspects of any of the specified requirements are not supported by this instance (either in general or in the current security context)
SecurityException- if the current security context does not have the permissions necessary to perform this operation
