Method Details

create

public static static T create(Class serviceInterfaceType, URI serviceUri)

Parameters:

serviceInterfaceType

serviceUri

create

public static static T create(Class serviceInterfaceType, URI serviceUri, ServicePartitionKey partitionKey, TargetReplicaSelector targetReplicaSelector, String listenerName)

Creates a proxy to communicate to the specified service using the remoted interface TServiceInterface that the service implements.

Parameters:

serviceInterfaceType - Interface type that is being remoted

serviceUri - Uri of the Service.

partitionKey - The Partition key that determines which service partition is responsible for handling requests from this service proxy

targetReplicaSelector - Determines which replica or instance of the service partition the client should connect to.

listenerName - This parameter is Optional if the service has a single communication listener. The endpoints from the service are of the form {"Endpoints":{"Listener1":"Endpoint1","Listener2":"Endpoint2" ...}}. When the service exposes multiple endpoints, this parameter identifies which of those endpoints to use for the remoting communication.

Returns:

The proxy that implement the interface that is being remoted. The returned object also implement ServiceProxy interface.

msgBodyValue

getResponseMessageBodyValue

protected Object getResponseMessageBodyValue(Object responseMessageBody)

Parameters:

responseMessageBody

getServiceInterfaceType

public Class getServiceInterfaceType()

The interface type that is being remoted.

Overrides:

ServiceProxyBase.getServiceInterfaceType()

Returns:

initialize

public void initialize(ServiceProxyGenerator serviceProxyGenerator, FabricServiceRemotingPartitionClient remotingPartitionClient)

Method to Initialize the service proxy instance. This is for internal use.

Parameters:

serviceProxyGenerator - instance of the serviceProxyGenerator
