Method Detail

setApplicationMembers

void setApplicationMembers(List<org.apache.axis2.clustering.Member> members)

Set the application members

Parameters:

members - The application members

setEndpoints

void setEndpoints(List<Endpoint> endpoints)

Set the endpoints

Parameters:

endpoints - The endpoints

setLoadBalanceEndpoint

void setLoadBalanceEndpoint(Endpoint endpoint)

Set the loadbalance endpoint

Parameters:

endpoint - the endpoint which uses this algorithm

getNextEndpoint

Endpoint getNextEndpoint(MessageContext synapseMessageContext,
                         AlgorithmContext algorithmContext)

This method returns the next node according to the algorithm implementation.

Parameters:

synapseMessageContext - SynapseMessageContext of the current message

algorithmContext - The context in which holds run time states related to the algorithm

Returns:

Next node for directing the message

getNextApplicationMember

org.apache.axis2.clustering.Member getNextApplicationMember(AlgorithmContext algorithmContext)

This method returns the next member to which the request has been sent to, according to the algorithm implementation.

Parameters:

algorithmContext - The context in which holds run time states related to the algorithm
