Class FilterCollectionWriter

java.io.Writer

org.apache.commons.io.output.FilterCollectionWriter

All Implemented Interfaces:

Closeable, Flushable, Appendable, AutoCloseable

Direct Known Subclasses:

ProxyCollectionWriter

public class FilterCollectionWriter
extends Writer

Abstract class for writing filtered character streams to a Collection of writers. This is in contrast to FilterWriter which is backed by a single Writer.

This abstract class provides default methods that pass all requests to the contained writers. Subclasses should likely override some of these methods.

The class Writer defines method signatures with throws IOException, which in this class are actually IOExceptionList containing a list of IOIndexedException.

Since:

2.7
