java.lang.Object
  fr.inrialpes.exmo.align.impl.edoal.TransfService

All Implemented Interfaces:

Cloneable, Visitable

public class TransfService
extends Object
implements Cloneable, Visitable

Represents a tranformation service to transform the values of attributes.

In the specification a transf is a local transformaion function/service. The pov specifies the parameters needed for the function to compute the transformaion.

In the specification a service is a remote transformaion function/service. The id distiguishes between multiple transformation function at the given address. The pov specifies the parameters needed for the function to compute the transformaion.

public TransfService(URI res,
                     Collection<Id> params)

Constructs a transf.

Parameters:

res - uri to the service

params - parameters for the transformation

Throws:

NullPointerException - if the res is null

public TransfService(URI res,
                     URI id,
                     Collection<Id> params)

Constructs a service.

Parameters:

res - uri to the service

id - id of the transformation function

params - parameters for the transformation

Throws:

NullPointerException - if the res is null

Method Detail

accept

public void accept(AlignmentVisitor visitor)
            throws AlignmentException

Specified by:

accept in interface Visitable

Throws:

AlignmentException

getRes

public URI getRes()

Returns the resource / uri to the transformation.

Returns:

the uri to the transformator

getId

public URI getId()
