Examples of com.google.caja.lexer.ExternalReference

com.google.caja.lexer.ExternalReference
A reference to an external resource from an input.
For example, parsing a file {@code x/y/foo.html} with contents:
```
 <script src="../z/bar.js"/> 
```
will result in an {@code ExternalReference} with:
- A {@link #getReferencePosition() reference position} which is the spanin {@code foo.html} where the reference occurred. This position contains,among other things, the URI {@code "x/y/foo.html"}.
- The target {@link #getUri() URI}, {@code "../z/bar.js"}.
Note that, in the case of HTML links (as in the above example), the URI is implicitly relative to the reference position; in other words, the author of {@code x/y/foo.html} meant to retrieve a script at{@code "x/z/bar.js"}. The {@code ExternalReference} itself, however, isoblivious to this level of interpretation. @author mikesamuel@gmail.com (Mike Samuel)
