Class LineScanner

java.lang.Object

java.io.Reader

asia.redact.bracket.properties.line.LineScanner

All Implemented Interfaces:

Closeable, AutoCloseable, Readable

public class LineScanner
extends Reader

This class was originally taken from Apache Harmony. The source is no longer online.

Read a properties file line by line using line().

The idea is that as we read lines, we return not the line text but a Line object which has knowledge of its internal parts, such as if the line has a key, is an extended line, etc.

There is one extension: a comment line which starts with #;; is treated as transient (not read in). This token is used later to generate a transient header and footer if desired.

Note: because this is a Reader, the caller must call close() on it when done.
