PolicyFinderResult |
findPolicy(EvaluationCtx context)
Finds the applicable policy (if there is one) for the given context.
|
PolicyFinderResult |
findPolicy(URI idReference,
int type,
VersionConstraints constraints,
PolicyMetaData parentMetaData)
Tries to find one and only one matching policy given the idReference
If more than one policy is found, this is an error and must be reported
as such.
|
void |
init(PolicyFinder finder)
Initializes this module for use by the given finder.
|
boolean |
isIdReferenceSupported()
Always returns true, since reference-based retrieval is supported.
|
boolean |
isRequestSupported()
Returns true if the module supports finding policies based on a
request (ie, target matching).

set(PolicySet ps,
List<AbstractPolicy> policies) |

PolicyFinderModule
PDP
is initialized with a
PDPConfig
containing the given PolicyFinder
.
Because PolicyFinderModule
s usually need to parse
policies, and this requires knowing their PolicyFinder,
parsing is usually done at or after this point in the lifetime
of this module. This might also be a good time to reset any internal
caches or temporary data. Note that this method may be called more
than once in the lifetime of a module.

idReference
- an identifier specifying some policytype
- type of reference (policy or policySet) as identified by
the fields in PolicyReference
constraints
- any optional constraints on the version of the
referenced policy (this will never be null, but
it may impose no constraints, and in fact will
never impose constraints when used from a pre-2.0
XACML policy)parentMetaData
- the meta-data from the parent policy, which
provides XACML version, factories, etc.public boolean isRequestSupported()
