Package org.apache.commons.io.output

Provides implementations of output classes, such as OutputStream and Writer.

Interface Summary

Interface	Description
UncheckedAppendable	An Appendable that throws UncheckedIOException instead of IOException.

Class Summary

Class	Description
AbstractByteArrayOutputStream	This is the base class for implementing an output stream in which the data is written into a byte array.
AppendableOutputStream<T extends java.lang.Appendable>	OutputStream implementation that writes the data to an Appendable Object.
AppendableWriter<T extends java.lang.Appendable>	Writer implementation that writes the data to an Appendable Object.
BrokenOutputStream	Broken output stream.
BrokenWriter	Always throws an IOException from all Writer methods.
ByteArrayOutputStream	Implements a ThreadSafe version of AbstractByteArrayOutputStream using instance synchronization.
ChunkedOutputStream	OutputStream which breaks larger output blocks into chunks.
ChunkedOutputStream.Builder	Builds a new UnsynchronizedByteArrayOutputStream instance.
ChunkedWriter	Writer which breaks larger output blocks into chunks.
ClosedOutputStream	Throws an IOException on all attempts to write to the stream.
ClosedWriter	Throws an IOException on all attempts to write with ClosedWriter.close() implemented as a noop.
CloseShieldOutputStream	Proxy stream that prevents the underlying output stream from being closed.
CloseShieldWriter	Proxy writer that prevents the underlying writer from being closed.
CountingOutputStream	A decorating output stream that counts the number of bytes that have passed through the stream so far.
DeferredFileOutputStream	An output stream which will retain data in memory until a specified threshold is reached, and only then commit it to disk.
DeferredFileOutputStream.Builder	Builds a new DeferredFileOutputStream instance.
DemuxOutputStream	Forwards data to a stream that has been associated with this thread.
FileWriterWithEncoding	Writer of files that allows the encoding to be set.
FileWriterWithEncoding.Builder	Builds a new FileWriterWithEncoding instance.
FilterCollectionWriter	Abstract class for writing filtered character streams to a Collection of writers.
LockableFileWriter	FileWriter that will create and honor lock files to allow simple cross thread file lock handling.
LockableFileWriter.Builder	Builds a new LockableFileWriter instance.
NullAppendable	Appends all data to the famous /dev/null.
NullOutputStream	Never writes data.
NullPrintStream	Never prints data.
NullWriter	Never writes data.
ProxyCollectionWriter	A Proxy stream collection which acts as expected, that is it passes the method calls on to the proxied streams and doesn't change which methods are being called.
ProxyOutputStream	A Proxy stream which acts as expected, that is it passes the method calls on to the proxied stream and doesn't change which methods are being called.
ProxyWriter	A Proxy stream which acts as expected, that is it passes the method calls on to the proxied stream and doesn't change which methods are being called.
QueueOutputStream	Simple alternative to JDK PipedOutputStream; queue input stream provides what's written in queue output stream.
StringBuilderWriter	Writer implementation that outputs to a StringBuilder.
TaggedOutputStream	An output stream decorator that tags potential exceptions so that the stream that caused the exception can easily be identified.
TaggedWriter	A writer decorator that tags potential exceptions so that the reader that caused the exception can easily be identified.
TeeOutputStream	Classic splitter of OutputStream.
TeeWriter	Classic splitter of Writer.
ThresholdingOutputStream	An output stream which triggers an event when a specified number of bytes of data have been written to it.
UncheckedFilterOutputStream	A FilterOutputStream that throws UncheckedIOException instead of UncheckedIOException.
UncheckedFilterOutputStream.Builder	Builds a new UncheckedFilterOutputStream instance.
UncheckedFilterWriter	A FilterWriter that throws UncheckedIOException instead of IOException.
UncheckedFilterWriter.Builder	Builds a new UncheckedFilterWriter instance.
UnsynchronizedByteArrayOutputStream	Implements a version of AbstractByteArrayOutputStream without any concurrent thread safety.
UnsynchronizedByteArrayOutputStream.Builder	Builds a new UnsynchronizedByteArrayOutputStream instance.
WriterOutputStream	OutputStream implementation that transforms a byte stream to a character stream using a specified charset encoding and writes the resulting stream to a Writer.
WriterOutputStream.Builder	Builds a new WriterOutputStream instance.
XmlStreamWriter	Character stream that handles all the necessary work to figure out the charset encoding of the XML document written to the stream.
XmlStreamWriter.Builder	Builds a new XmlStreamWriter instance.
