permission check. |

Returns: true
to indicate the value returned by
isSatisfied can change. Otherwise, false

true
if the
evaluation of the Condition must be postponed until the end of the
permission check. If this method returns false
, this
Condition must be able to directly answer the isSatisfied
method. In other words, isSatisfied() will return very quickly since no
external sources, such as for example users, need to be consulted.
Returns: true
to indicate the evaluation must be postponed.
Otherwise, false
if the evaluation can be
immediately performed.
Returns: true
to indicate the Conditions is satisfied.
Otherwise, false
if the Condition is not satisfied.
Parameters: conditions The array of Conditions. context A Dictionary object that implementors can use to track state. If this method is invoked multiple times in the same permission evaluation, 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 invocatios are needed.
Returns: true
if all the Conditions are satisfied.
Otherwise, false
if one of the Conditions is not
satisfied.
