com.logicaldoc.core.parser.wordperfect.WPFilterInputStream

All Implemented Interfaces:

Closeable, AutoCloseable

public class WPFilterInputStream
extends FilterInputStream

A FilterInputStream that processes bytes that have a special meaning in WordPerfect documents. Processed characters are: 0x80 (space character in WP 6), 0xA9 (hyphen in WP 6) and 0xAC (word break indicator).

This class is made available as a utility class as other file formats may also use WordPerfect's file structure, e.g. Corel Presentations 3.0 files.
