Class QueryRuntimeFilterFactory.ChildFilter

java.lang.Object

net.sf.basedb.core.QueryRuntimeFilterFactory.ChildFilter

All Implemented Interfaces:

QueryRuntimeFilter

Enclosing class:

QueryRuntimeFilterFactory

static class QueryRuntimeFilterFactory.ChildFilter
extends Object
implements QueryRuntimeFilter

An optional filter that can be used by BasicItem:s to replace the QueryRuntimeFilterFactory.BasicFilter. This filter checks if the logged in user has generic permission EntityQuery.getItemPermission() for a parent item, instead of the actual item returned by a query. In a parent/child relationship it is the permissions on the parent item that controls the permission on the child. For example, Client is the parent of Help.

If the logged in user doesn't have the requested permission on the parent item, the denyAll filter is enabled.

enableFilters

public void enableFilters(QueryRuntimeFilterManager manager,
 EntityQuery query,
 DbControl dc)

Description copied from interface: QueryRuntimeFilter

Enable the filters based on the options specified by the query and the logged in users permissions. Implementors should use the manager to enable the filters, not the HibernateUtil.enableFilter() method. The manager keeps track of already enabled filters and also takes care of disabling all filters after the query has been executed.

Specified by:

enableFilters in interface QueryRuntimeFilter

Parameters:

manager - A manager that is used to actually enabled the filter

query - The query that is going to be executed, it is not possible to modify the query, the actual HQL may already have been generated

dc - The DbControl used for database access and permission checking
