Interface GroupProvider

All Known Implementing Classes:

DefaultGroupProvider, JDBCGroupProvider, LdapGroupProvider

public interface GroupProvider

Provider interface for groups. Users that wish to integrate with their own group system must implement this class and then register the implementation with Wildfire in the wildfire.xml file. An entry in that file would look like the following:

   <provider>
     <group>
       <className>com.foo.auth.CustomGroupProvider</className>
     </group>
   </provider>

Returns the group names that match a search given a start index and desired number of results. The search is over group names and implicitly uses wildcard matching (although the exact search semantics are left up to each provider implementation). For example, a search for "HR" should match the groups "HR", "HR Department", and "The HR People".

Before searching or showing a search UI, use the isSearchSupported() method to ensure that searching is supported.

Parameters:

query - the search string for group names.

startIndex - start index in results.
