Return the text of all tokens within the specified {@code interval}. This
method behaves like the following code (including potential exceptions
for violating preconditions of {@link #get}, but may be optimized by the
specific implementation.
<pre>
TokenStream stream = ...;
String text = "";
for (int i = interval.a; i <= interval.b; i++) {
text += stream.get(i).getText();
}
</pre>
@param interval The interval of tokens within this stream to get text
for.
@return The text of all tokens within the specified interval in this
stream.
@throws NullPointerException if {@code interval} is {@code null}
