How to set name which is unique for a component based on thier properties?

I want to differentiate each component in my application uniquely.So how can i prepare an unique name with its properties so that i can set this name. In my testing tool i have to perform action on the correct component. I tried name preparing like

String parentName = component.getParent();
String xpoint = component.getX();
String ypoint = component.getY();
component.setName(parentName_xpoint_ypoint);

Can you tell me whatever i tried will give the unique component if i call using
component.getName().equals(parentName_xpoint_ypoint) ?
