Method Detail

getDescendantPolicyTreeElements

public java.util.Collection getDescendantPolicyTreeElements(com.sun.xacml.PolicyTreeElement parent)
Gets teh Collection of all POlicyElements that are Descendants of specified PolicyTreeElement


getDescendantPolicyTreeElement

public com.sun.xacml.PolicyTreeElement getDescendantPolicyTreeElement(com.sun.xacml.PolicyTreeElement parent,
                                                                      java.net.URI descendantId)
Get the descendent AbstractPolciy composed within specified PolicyTreeElement object that matches the specified id.


isRequestSupported

public boolean isRequestSupported()
Returns true if the module supports finding policies based on a request (ie, target matching). By default this method returns false.

Overrides:
isRequestSupported in class com.sun.xacml.finder.PolicyFinderModule
Returns:
true if request retrieval is supported

isIdReferenceSupported

public boolean isIdReferenceSupported()
Returns true if the module supports finding policies based on an id reference (in a PolicySet). By default this method returns false.

Overrides:
isIdReferenceSupported in class com.sun.xacml.finder.PolicyFinderModule
Returns:
true if idReference retrieval is supported

init

public void init(com.sun.xacml.finder.PolicyFinder finder)
Specified by:
init in class com.sun.xacml.finder.PolicyFinderModule

findPolicy

public com.sun.xacml.finder.PolicyFinderResult findPolicy(com.sun.xacml.EvaluationCtx context)
Finds a policy based on a request's context. Returns the custom Policy associated with resource if any, otherwise return the registry's default Policy. This will always do a Target match to make sure that the given policy applies.

Overrides:
findPolicy in class com.sun.xacml.finder.PolicyFinderModule
Parameters:
context - the representation of the request data
Returns:
the result of trying to find an applicable policy

findPolicy

public com.sun.xacml.finder.PolicyFinderResult findPolicy(java.net.URI idReference,
                                                          int type)
Tries to find one and only one matching policy given the idReference First it tries to find a RegistryObject with specified URI as id. If none is found, it tries to find an ACP with specified URI as a value for a Slot named "ComposedPolicies".

Overrides:
findPolicy in class com.sun.xacml.finder.PolicyFinderModule
Parameters:
idReference - an identifier specifying some policy
