Examples of com.opengamma.engine.view.client.ViewClient.attachToViewProcess()

com.opengamma.engine.view.client.ViewClient.attachToViewProcess()
Attaches the client to a shared view process, which might involve creating a new process.
As part of this call, the client is updated with the latest state of the view process which may result in listeners being invoked, depending on the state of the client. @param definitionId the unique ID of the view definition, not null @param executionOptions the view execution options, not null @throws IllegalStateException if the client is already attached to a process

    client.detachFromViewProcess();
    assertEquals(ViewProcessState.RUNNING, viewProcess.getState());


    resultListener.assertNoCalls(Timeout.standardTimeoutMillis());


    client.attachToViewProcess(env.getViewDefinition().getUniqueId(), ExecutionOptions.infinite(MarketData.live(), ExecutionFlags.none().get()));
    final ViewProcessImpl viewProcess2 = env.getViewProcess(vp, client.getUniqueId());
    assertEquals(viewProcess, viewProcess2);


    resultListener.expectNextCall(ViewDefinitionCompiledCall.class, Timeout.standardTimeoutMillis());
