public class BasicPolicyFinderModule
This is a basic implementation of PolicyFinderModule
that
accepts already created AbstractPolicy
s and supports
finding by context and reference. All policies are held forever once
added to this module, and cannot be refreshed or removed. New policies
may be added at any point. You may optionally specify a combining
algorithm to use when more than one applicable policy is found, and then
a new PolicySet is wrapped around the policies using this algorithm. If
no combining algorithm is provided, then an error is returned if more
than one policy matches.
This module is provided as an example, but is still fully functional, and
should be useful for many simple applications. This is provided in the
support
package rather than the core codebase because it
implements non-standard behavior.
Constructor Summary | |
---|---|
BasicPolicyFinderModule()
Creates a BasicPolicyFinderModule . |
|
BasicPolicyFinderModule(PolicyCombiningAlgorithm combiningAlg)
Creates a BasicPolicyFinderModule that can combine
multiple applicable policies under a single, dynamic PolicySet. |
Method Summary | |
---|---|
boolean |
addPolicy(AbstractPolicy policy)
Adds a policy that will be available both by reference and by matching to a context. |
boolean |
addPolicyNoRef(AbstractPolicy policy)
Adds a policy that will be available only by matching to a context. |
boolean |
addPolicyOnlyRef(AbstractPolicy policy)
Adds a policy that will be available only by reference. |
PolicyFinderResult |
findPolicy(EvaluationCtx context)
Finds a policy based on a request's context. |
PolicyFinderResult |
findPolicy(URI idReference,
int type,
VersionConstraints constraints,
PolicyMetaData parentMetaData)
Attempts to find a policy by reference, based on the provided parameters. |
void |
init(PolicyFinder finder)
Initialize this module. |
boolean |
isIdReferenceSupported()
Always returns true since this module does support
finding policies based on reference. |
boolean |
isRequestSupported()
Always returns true since this module does support
finding policies based on context matching. |

- an identifier specifying some policytype

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

- the meta-data from the parent policy, which
provides XACML version, factories, etc.
