API Documentation

The module exposes only two functions.

$3

Provided with an existing Range instance this will return an object that
stores the offsets of the beginning and end of the text selected by the range as
measured from the beginning of the root Node.

$3

This method returns a Range object that covers the interval [start, end) of
the text content of the root Node.

If the end is not provided, returns a collapsed range. If the start is not
provided, the default is 0.

If the start or end offsets are outside the range of valid character offsets
within the text content of the root node, an exception is thrown.
