Detailed Description

The position of a token start, end, or other feature.

Since the Lexer works on character buffers, and a given token may extend across several buffers, it also needs a way to communicate which buffer a particular token started or ended in. To this end, since the Lexer reports the positions in the buffer of token beginnings and endings, it reports those positions using an identifier (i.e. handle) for which buffer the position was in, what the offset is from that buffer.

An offset may point one past the last achracter in the buffer identified by the handle.

This whole system is designed with three goals:

• Reduce the amount of information that has to be copied.
• Open up as much code to the optimizer as possible.
• Make sure each character in an XML document is only processed once on the way to a parse tree.
