Examples with StreamHandler com.ibm.streams.flow.handlers.StreamHandler used on opensource projects

Example 1 with StreamHandler

use of com.ibm.streams.flow.handlers.StreamHandler in project streamsx.topology by IBMStreams.

the class TupleCollection method setupEmbeddedTestHandlers.

public void setupEmbeddedTestHandlers(JavaTestableGraph tg) throws Exception {
    for (TStream<?> stream : handlers.keySet()) {
        Set<StreamHandler<Tuple>> streamHandlers = handlers.get(stream);
        for (StreamHandler<Tuple> streamHandler : streamHandlers) {
            BOutput output = stream.output();
            if (output instanceof BOutputPort) {
                BOutputPort outputPort = (BOutputPort) output;
                tg.registerStreamHandler(outputPort.port(), streamHandler);
            }
        // tg.registerStreamHandler(stream.getPort(), streamHandler);
        }
    }
}

Example 2 with StreamHandler

use of com.ibm.streams.flow.handlers.StreamHandler in project streamsx.topology by IBMStreams.

the class EmbeddedTesterRuntime method setupEmbeddedTestHandlers.

private void setupEmbeddedTestHandlers(EmbeddedGraph eg) throws Exception {
    // Embedded does not support a StreamHandler against
    // a connected stream. In that case add a no-op intermediate stream.
    Set<TStream<?>> adds = new HashSet<>();
    // Find all that are connected.
    for (TStream<?> stream : handlers.keySet()) {
        if (stream.output().isConnected())
            adds.add(stream);
    }
    // Insert a filter for the handler.
    for (TStream<?> stream : adds) {
        TStream<?> filter = stream.filter(t -> true);
        Set<StreamHandler<Tuple>> handler = handlers.get(stream);
        handlers.remove(stream);
        handlers.put(filter, handler);
    }
    final JavaTestableGraph tg = eg.getExecutionGraph();
    for (TStream<?> stream : handlers.keySet()) {
        Set<StreamHandler<Tuple>> streamHandlers = handlers.get(stream);
        final BOutput output = stream.output();
        final OutputPortDeclaration portDecl = eg.getOutputPort(output.name());
        for (StreamHandler<Tuple> streamHandler : streamHandlers) {
            tg.registerStreamHandler(portDecl, streamHandler);
        }
    }
