| This service allows components to modify
org.cougaar.core.adaptivity.AdaptivityEngine plays and playbooks.
This part of the service is used to alter the plays in the playbook
by adding, modifying, or removing OperatingMode Policies.
Play - if THREATCON > 3 && ENCLAVE == THEATER
then ENCRYPT = {56, 128} - the first value is preferred
Policy - if THREATCON > 3 && CPU > 90
then ENCRYPT >= 128
Plays formed by calling constrain(Policy)
if (THREATCON > 3 && ENCLAVE == THEATER)
&& (THREATCON >3 && CPU > 90)
then ENCRYPT = {128}
if (THREATCON > 3 && ENCLAVE == THEATER)
&& !(THREATCON >3 && CPU > 90)
then ENCRYPT = {56, 128}
This play can constrain this policy because their "then" clauses
are operating on the same knobs.
Two plays result from constraining the original play with the
policy. The "if" clause of the first new play has the "if" clause
of the policy tacked on to it, and the knob on the "then" clause
must be set to 128. The "if" clause on the second new play has
the -negated- "if" clause of the policy tacked on. The "then"
clause is untouched.
