All Implemented Interfaces:

org.osgi.service.condpermadmin.ConditionalPermissionAdmin

public final class ConditionalPermissionAdminImpl
extends Object
implements org.osgi.service.condpermadmin.ConditionalPermissionAdmin

An implementation of the ConditionalPermissionAdmin service that doesn't need to have a framework specific security manager set. It use the DomainGripper to know what bundleprotectiondomains are expected.

hasPermission

public boolean hasPermission(org.apache.felix.framework.BundleRevisionImpl module,
                             org.apache.felix.framework.cache.Content content,
                             ProtectionDomain pd,
                             Permission permission,
                             boolean direct,
                             Object admin)

This method does the actual permission check. If it is not a direct check it will try to determine the other bundle domains that will follow automatically in case this is the first check in one permission check. If not then it will keep track of which domains we have already see. While it keeps track it builds up a list of postponed tuples which it will evaluate at the last domain. See the core spec 9.5.1 and following for a general description.

Parameters:

felixBundle - the bundle in question.

loader - the content loader of the bundle to get access to the jar to check for local permissions.

root - the bundle id.

signers - the signers (this is to support the ACC based on signers)

pd - the bundle protection domain

permission - the permission currently checked

direct - whether this is a direct check or not. direct check will not expect any further bundle domains on the stack

Returns:

true in case the permission is granted or there are postponed tuples false if not. Again, see the spec for more explanations.
