PolicyFinderResult |
findPolicy(EvaluationCtx evaluationCtx)
Tries to find one and only one matching policy given the request
represented by the context data.
|
PolicyFinderResult |
findPolicy(URI arg0,
int arg1,
VersionConstraints arg2,
PolicyMetaData arg3)
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 policyFinder)
Initializes this module for use by the given finder.
|
boolean |
isRequestSupported()
Returns true if the module supports finding policies based on a
request (ie, target matching).

public void init(PolicyFinder policyFinder)
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.

it may impose no constraints, and in fact will
never impose constraints when used from a pre-2.0
