serviceProxy

<T> T serviceProxy(String name,
                   Class<? super T> svcItf,
                   boolean sticky,
                   @Nullable
                   @Nullable Supplier<Map<String,Object>> callAttrsProvider,
                   long timeout)
            throws IgniteException

Gets a remote handle on the service. If service is available locally and no caller context provider is specified, then a local instance is returned and the timeout is ignored, otherwise, a proxy is dynamically created and provided for the specified service.

Type Parameters:

T - Service type.

Parameters:

name - Service name.

svcItf - Interface for the service.

sticky - Whether or not Ignite should always contact the same remote service or try to load-balance between services.

callAttrsProvider - Service call context attributes provider.

timeout - If greater than 0 created proxy will wait for service availability only specified time, and will limit remote service invocation time.

Returns:

Either proxy over remote service or local service if it is deployed locally and no caller context provider is specified.

Throws:

IgniteException - If failed to create service proxy.
