DuckTape Module Creation

Module is the basic computational unit that can be composed in DuckTape workflow.

#Java Domain

To define DuckTape module based on existing Java class, we can use annotation. The class which we wanted to use as module needs to be annotated with @Module annotation.

Input Annotation

To identify inputs to a module, we can use annotation to mark a class field or a function parameter as an input of a module.

###Input Annotation on constructors

@Module(name="LibLINEARParms")
public class LibLINEARParmsModule {
    public LibLINEARParmsModule(
            @In(name="cs") List<Double> cs, 
            @In(name="nrFolds") int folds, 
            @In(name="target") List<Double> target
            ) {
        cv = true;
        this.cs = cs;
        this.target = target;
        this.nrFolds = folds;
    }
}

###Input annotation on fields @Module(name="Adder", description="Adds two numbers together.") public class AdderModule { @In(name="first") public Integer first; @In(name="second") public Integer second }

Output Annotation
