Class ThrowingPrintWriter

java.lang.Object

java.io.Writer

java.io.OutputStreamWriter

com.facebook.buck.util.ThrowingPrintWriter

All Implemented Interfaces:

Closeable, Flushable, Appendable, AutoCloseable

public class ThrowingPrintWriter
extends OutputStreamWriter

A (partial) replacement for PrintWriter with methods that throw IOException. PrintWriter explicitly does not throw, and that can catch people off guard.

Only the methods that were in use in Buck at the time this class was written have been implemented (including primitive overloads to prevent accidental inefficiencies later). Feel free to add more methods, but please don't go beyond what PrintWriter itself has.
