I can tell the difference between getCorrespondingResource() and the above two methods. But for getResource and getUnderlyingResource , the description seems like the same.

Quote:

Returns the smallest underlying resource that contains this element, or null if this element is not contained in a resource.

Quote:

Returns the innermost resource enclosing this element.

Could somebody give some example when these two methods returns different result?

For a working copy compilation unit, a type within that unit (or a method within that type), these two methods produce different results. For such a method and type, the

getResource()

returns the file as the result. But

getUnderlyingResource()

returns null. However, for a non working copy unit, these two methods produce the same result.
