- ALF-9322: RINF 11: AbstractCannedQueryPermissions enhancements - Pulled in logic around hasMore() so that subclasses just have to obey - Added in cut-off size estimates - ALF-9337: RINF 11: Consolidate interceptor wrappers - Permissions respect PermissionCheckedValue - Added last-in-chain "afterAclMarking" to "afterInvocationManager": marks collections as checked - Added 'mixin' interfaces to handle input and output for permission checking of collections git-svn-id: https://svn.alfresco.com/repos/alfresco-enterprise/alfresco/HEAD/root@28734 c4b6b30b-aa2e-2d43-bbcb-ca4b014f7261
