Example 36 with TStream

use of com.ibm.streamsx.topology.TStream in project streamsx.topology by IBMStreams.

the class LowLatencyTest method testNested.

@Test

    // ensure nested low latency yields all fns in the same container
    final Topology topology = newTopology();
    final Tester tester = topology.getTester();
