Class MobyServiceComparator

java.lang.Object
  org.biomoby.registry.rdfagent.verifier.MobyServiceComparator

public class MobyServiceComparator
extends Object

This class compares 2 services and determines what it is that is different between them. If you are interested in the validity of the inputs/outputs for a particular service, then take a look at areInputsOutputsForServiceValid(MobyService).

To use this class, do the following:

 
                // create 2 services and do stuff with them
                MobyService service1 = new MobyService();
                MobyService service2 = new MobyService();
    
                ...
    
                // now use the MobyServiceComparator class 
                MobyServiceComparator c = new MobyServiceComparator();
                if (c.areServicesDifferent(service1, service2)) {
                        // print out the differences
                        System.out.println(c.getDifferences());
                } else {
                        System.out.println("The 2 services are identical");
                }
     
                // lets check if the inputs and outputs for service 1 are valid
                if (c.areInputsOutputsForServiceValid(service1)) {
                        System.out.println("The inputs/outputs are valid!");
                }

Method Detail

areServicesDifferent

public boolean areServicesDifferent(MobyService service1,
                                    MobyService service2)

Parameters:

service1 - a service to compare to service2

service2 - a service to compare with service1

Returns:

true if the service signatures are not equal, false otherwise. For services that are null, true is always returned.

areInputsOutputsForServiceValid

public boolean areInputsOutputsForServiceValid(MobyService service)

Parameters:

service - a MobyService object

Returns:

true if the service has inputs and outputs that are structured correctly, i.e. are all named, false otherwise.

getDifferences

public String getDifferences()

Returns:

a string of differences for the last comparison of services

getServiceErrors

public String getServiceErrors(MobyService s)

Parameters:

s - the service to attempt to extract the errors from

Returns:

a string of possible reasons for the prevention of this service to be registered with a registry
