Flushable

java.io.Flushable

Known Indirect Subclasses

BufferedOutputStream, BufferedWriter, ByteArrayOutputStream, CharArrayWriter, CheckedOutputStream, ChunkedOutputStream, CipherOutputStream, Console, DataOutputStream, DeflaterOutputStream, DerOutputStream, DigestOutputStream, FileOutputStream, FileWriter, FilterOutputStream, and 26 others.

BufferedOutputStream	The class implements a buffered output stream.
BufferedWriter	Writes text to a character-output stream, buffering characters so as to provide for the efficient writing of single characters, arrays, and strings.
ByteArrayOutputStream	This class implements an output stream in which the data is written into a byte array.
CharArrayWriter	This class implements a character buffer that can be used as an Writer.
CheckedOutputStream	An output stream that also maintains a checksum of the data being written.
ChunkedOutputStream	OutputStream that sends the output to the underlying stream using chunked encoding as specified in RFC 2068.
CipherOutputStream	A CipherOutputStream is composed of an OutputStream and a Cipher so that write() methods first process the data before writing them out to the underlying OutputStream.
Console	Methods to access the character-based console device, if any, associated with the current Java virtual machine.
DataOutputStream	A data output stream lets an application write primitive Java data types to an output stream in a portable way.
DeflaterOutputStream	This class implements an output stream filter for compressing data in the "deflate" compression format.
DerOutputStream	Output stream marshaling DER-encoded data.
DigestOutputStream	A transparent stream that updates the associated message digest using the bits going through the stream.
FileOutputStream	A file output stream is an output stream for writing data to a `File` or to a `FileDescriptor`.
FileWriter	Convenience class for writing character files.
FilterOutputStream	This class is the superclass of all classes that filter output streams.
FilterWriter	Abstract class for writing filtered character streams.
Formatter	An interpreter for printf-style format strings.
FtpURLConnection.FtpOutputStream	For FTP URLs we need to have a special OutputStream because we need to close 2 sockets after we're done with it : - The Data socket (for the file).
GZIPOutputStream	This class implements a stream filter for writing compressed data in the GZIP file format.
IndentingWriter	A BufferedWriter that supports automatic indentation of lines of text written to the underlying Writer.
InflaterOutputStream	Implements an output stream filter for uncompressing data stored in the "deflate" compression format.
JarOutputStream	The `JarOutputStream` class is used to write the contents of a JAR file to any output stream.
LogOutputStream
LogStream	This class is deprecated. no replacement
MarshalOutputStream	A MarshalOutputStream extends ObjectOutputStream to add functions specific to marshaling of remote object references.
ObjectOutputStream	An ObjectOutputStream writes primitive data types and graphs of Java objects to an OutputStream.
OutputSink
OutputStream	This abstract class is the superclass of all classes representing an output stream of bytes.
OutputStreamWriter	An OutputStreamWriter is a bridge from character streams to byte streams: Characters written to it are encoded into bytes using a specified `charset`.
PipedOutputStream	A piped output stream can be connected to a piped input stream to create a communications pipe.
PipedWriter	Piped character-output streams.
PosterOutputStream	Instances of this class are returned to applications for the purpose of sending user data for a HTTP POST or PUT request.
PrintStream	A `PrintStream` adds functionality to another output stream, namely the ability to print representations of various data values conveniently.
PrintWriter	Prints formatted representations of objects to a text-output stream.
RIFFWriter	Resource Interchange File Format (RIFF) stream encoder.
StreamEncoder
StringWriter	A character stream that collects its output in a string buffer, which can then be used to construct a string.
TelnetOutputStream	This class provides input and output streams for telnet clients.
TypeScriptWriter
Writer	Abstract class for writing to character streams.
ZipOutputStream	This class implements an output stream filter for writing files in the ZIP file format.

Class Overview

A Flushable is a destination of data that can be flushed. The flush method is invoked to write any buffered output to the underlying stream.

Summary

Public Methods
abstract void	flush() Flushes this stream by writing any buffered output to the underlying stream.

Public Methods

public abstract void flush ()

Flushes this stream by writing any buffered output to the underlying stream.

Throws

IOException	If an I/O error occurs
