PolicyFinderResult |
findPolicy(EvaluationCtx context)
Tries to find one and only one matching policy given the request represented by the context
data.
|
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()
Returns true if the module supports finding policies based on an id reference (in a
PolicySet).
|
boolean |
isRequestSupported()
Returns true if the module supports finding policies based on a request (ie, target
matching).
|
void |
loadPolicies()
Re-sets the policies known to this module to those contained in the
given files.

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.
