- The array of Condition objects, which must all be of
the same class and mutable. The receiver must be one of those
Condition objects.context
- A Dictionary object that implementors can use to track
state. If this method is invoked multiple times in the same
permission check, the same Dictionary will be passed multiple
times. The SecurityManager treats this Dictionary as an opaque
object and simply creates an empty dictionary and passes it to
subsequent invocations if multiple invocations are needed.true
if all the Condition objects are satisfied.
Otherwise, false
if one of the Condition objects is
not satisfied.Copyright © 2012 JBoss by Red Hat. All Rights Reserved.
