getSource
public Object getSource()
Description copied from interface:Element
Returns an arbitrary object containing information about the "place" where this element was configured. Used by Guice in the production of descriptive error messages.Tools might specially handle types they know about;
StackTraceElement
is a good example. Tools should simply calltoString()
on the source object if the type is unfamiliar.
