Example 1 with SPLGenerator

use of com.ibm.streamsx.topology.generator.spl.SPLGenerator in project streamsx.topology by IBMStreams.

the class ToolkitRemoteContext method generateSPL.

private void generateSPL(File toolkitRoot, JsonObject jsonGraph) throws IOException {
    // Create the SPL file, and save a copy of the JSON file.
    SPLGenerator generator = new SPLGenerator();
    createNamespaceFile(toolkitRoot, jsonGraph, "spl", generator.generateSPL(jsonGraph));
    createNamespaceFile(toolkitRoot, jsonGraph, "json", jsonGraph.toString());
}

Example 2 with SPLGenerator

use of com.ibm.streamsx.topology.generator.spl.SPLGenerator in project streamsx.topology by IBMStreams.

the class LowLatencyTest method threadedPortTest.

    // Construct topology
    TStream<String> ss = topology.strings("hello").lowLatency();
