public BInputPort inputFrom(BOutput output, BInputPort input) {
    if (input != null) {
        assert input.operator() == this.op;
        assert inputs != null;

    }
    if (inputs == null) {
        inputs = new ArrayList<>();
    }
    InputPortDeclaration inputPort = op.addInput(this.op.getName() + "_IN" + inputs.size(), output.schema());
    input = new BInputPort(this, inputPort);
    inputs.add(input);
    output.connectTo(input);
    return input;

use of com.ibm.streams.flow.declare.InputPortDeclaration in project streamsx.topology by IBMStreams.

the class EmbeddedGraph method declareInputs.

private void declareInputs(OperatorInvocation<? extends Operator> opDecl, JsonArray inputs) {
    if (jisEmpty(inputs))
        return;
    // Ensure we deal with them in port order.
    JsonObject[] ports = new JsonObject[inputs.size()];
    for (JsonElement e : inputs) {
        JsonObject input = e.getAsJsonObject();
        ports[input.get("index").getAsInt()] = input;
    }
    for (JsonObject input : ports) {
        String name = jstring(input, "name");
        StreamSchema schema = Type.Factory.getTupleType(jstring(input, "type")).getTupleSchema();
        InputPortDeclaration port = opDecl.addInput(name, schema);
        assert !inputPorts.containsKey(name);
        inputPorts.put(name, port);
        if (input.has("window"))
            windowInput(input, port);
    }
}
