Class FindReplaceWriter

java.lang.Object

java.io.Writer

com.aoindustries.io.FindReplaceWriter

All Implemented Interfaces:

Closeable, Flushable, Appendable, AutoCloseable

public class FindReplaceWriter
extends Writer

Replaces strings while writing.

This class is not thread safe and requires external synchronization if used by more than one thread.

This is a simple implementation that forces all writes to be one character at a time. It is recommended to use along with BufferedWriter when used in a performance-sensitive application.
