TaskSignatureComponent

JTaskSignatureComponent

For example, if you want to use a custom Signature Component that just wants to use JFilePathModifier for a parameter aimed for a file name, you could do it like this:

public class MySignatureComponent extends JTaskSignatureComponent {

    private static final long serialVersionUID = 1L;

    protected Map<TaskParameter, Modifier> makeModifierMap() {

	SignatureApi signature = getSignature();
	Map<TaskParameter, Modifier> map =
	    new LinkedHashMap<TaskParameter, Modifier>();

	map.put(signature.getTaskParameter("file"), new JFilePathModifier());
	map.put(signature.getTaskParameter("number"), new JIntegerModifier());

	return map;
    }
}

In package herschel.ia.gui.apps.modifier you can find more general available modifiers.
