All Implemented Interfaces:

PolicyConfiguration

public class SimplePolicyConfiguration
extends java.lang.Object
implements PolicyConfiguration

Author:

monzillo The methods of this interface are used by containers to create policy statements in a Policy provider. An object that implements the PolicyConfiguration interface provides the policy statement configuration interface for a corresponding policy context within the corresponding Policy provider.

This method returns this object's policy context identifier.

Specified by:

getContextID in interface PolicyConfiguration

linkConfiguration

public void linkConfiguration(PolicyConfiguration link)
                       throws PolicyContextException

Creates a relationship between this configuration and another such that they share the same principal-to-role mappings. PolicyConfigurations are linked to apply a common principal-to-role mapping to multiple seperately manageable PolicyConfigurations, as is required when an application is composed of multiple modules.

Note that the policy statements which comprise a role, or comprise the excluded or unchecked policy collections in a PolicyConfiguration are unaffected by the configuration being linked to another.

Specified by:

linkConfiguration in interface PolicyConfiguration

Parameters:

link - a reference to a different PolicyConfiguration than this PolicyConfiguration.

The relationship formed by this method is symetric, transitive and idempotent. If the argument PolicyConfiguration does not have a different Policy context identifier than this PolicyConfiguration no relationship is formed, and an exception, as described below, is thrown.

Throws:

java.lang.SecurityException - if called by an AccessControlContext that has not been granted the "setPolicy" SecurityPermission.

java.lang.UnsupportedOperationException - if the state of the policy context whose interface is this PolicyConfiguration Object is "deleted" or "inService" when this method is called.

java.lang.IllegalArgumentException - if called with an argument PolicyConfiguration whose Policy context is equivalent to that of this PolicyConfiguration.

PolicyContextException - if the implementation throws a checked exception that has not been accounted for by the linkConfiguration method signature. The exception thrown by the implementation class will be encapsulated (during construction) in the thrown PolicyContextException.

delete

public void delete()
            throws PolicyContextException

Causes all policy statements to be deleted from this PolicyConfiguration and sets its internal state such that calling any method, other than delete, getContextID, or inService on the PolicyConfiguration will be rejected and cause an UnsupportedOperationException to be thrown.

This operation has no affect on any linked PolicyConfigurations other than removing any links involving the deleted PolicyConfiguration.

Specified by:

delete in interface PolicyConfiguration

Throws:

java.lang.SecurityException - if called by an AccessControlContext that has not been granted the "setPolicy" SecurityPermission.

PolicyContextException - if the implementation throws a checked exception that has not been accounted for by the delete method signature. The exception thrown by the implementation class will be encapsulated (during construction) in the thrown PolicyContextException.

commit

public void commit()
            throws PolicyContextException

This method is used to set to "inService" the state of the policy context whose interface is this PolicyConfiguration Object. Only those policy contexts whose state is "inService" will be included in the policy contexts processed by the Policy.refresh method. A policy context whose state is "inService" may be returned to the "owpen" state by calling the getPolicyConfiguration method of the PolicyConfiguration factory with the policy context identifier of the policy context.

When the state of a policy context is "inService", calling any method other than commit, delete, getContextID, or inService on its PolicyConfiguration Object will cause an UnsupportedOperationException to be thrown.

Specified by:

commit in interface PolicyConfiguration

Throws:

java.lang.SecurityException - if called by an AccessControlContext that has not been granted the "setPolicy" SecurityPermission.

java.lang.UnsupportedOperationException - if the state of the policy context whose interface is this PolicyConfiguration Object is "deleted" when this method is called.

PolicyContextException - if the implementation throws a checked exception that has not been accounted for by the commit method signature. The exception thrown by the implementation class will be encapsulated (during construction) in the thrown PolicyContextException.

inService

public boolean inService()
                  throws PolicyContextException

This method is used to determine if the policy context whose interface is this PolicyConfiguration Object is in the "inService" state.

Specified by:

inService in interface PolicyConfiguration

Returns:

true if the state of the associated policy context is "inService"; false otherwise.

Throws:

java.lang.SecurityException - if called by an AccessControlContext that has not been granted the "setPolicy" SecurityPermission.

PolicyContextException - if the implementation throws a checked exception that has not been accounted for by the inService method signature. The exception thrown by the implementation class will be encapsulated (during construction) in the thrown PolicyContextException.
