TokenSpan

public class TokenSpan extends Object

Object

└ TokenSpan

Represents a half-open token range [start, end) within a single source line.

TokenSpan avoids allocating substring copies during line-by-line syntax highlighting. Callers can extract the underlying text on demand via slice(line).

import klyn.code

span = TokenSpan(0, 6, TokenKind.KEYWORD)
assert span.length == 6
assert span.slice("public class Foo:") == "public"
