Examples of ClusteringAgent

org.apache.axis2.clustering.ClusteringAgent
afkham.org/2008/05/group-membership-management-schemes.html"> membership scheme, this members are read from the axis2.xml file and added to the ClusteringAgent.

In the axis2.xml, the instance of this interface is specified using the "clustering" class attribute. e.g. <clustering class="org.apache.axis2.clustering.tribes.TribesClusterAgent"> specifies that the TribesClusterAgent class is the instance of this interface that needs to be used.

There can also be several "parameter" elements, which are children of the "clustering" element in the axis2.xml file. Generally, these parameters will be specific to the ClusteringAgent implementation.
