Flushable

interface Flushable

java.io.Flushable

Known Direct Subclasses Console, Formatter, OutputStream, Writer Console Methods to access the character-based console device, if any, associated with the current Java virtual machine. Formatter An interpreter for printf-style format strings. OutputStream This abstract class is the superclass of all classes representing an output stream of bytes. Writer Abstract class for writing to character streams.

Known Indirect Subclasses AssetFileDescriptor.AutoCloseOutputStream, Base64OutputStream, BufferedOutputStream, BufferedWriter, ByteArrayOutputStream, CharArrayWriter, CheckedOutputStream, CipherOutputStream, DataOutputStream, DeflaterOutputStream, DigestOutputStream, FileOutputStream, and 15 others. AssetFileDescriptor.AutoCloseOutputStream An OutputStream you can create on a ParcelFileDescriptor, which will take care of calling android. Base64OutputStream An OutputStream that does Base64 encoding on the data written to it, writing the resulting data to another OutputStream. 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. 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. 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. 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 Writes text to character files using a default buffer size. FilterOutputStream This class is the superclass of all classes that filter output streams. FilterWriter Abstract class for writing filtered character streams. GZIPOutputStream This class implements a stream filter for writing compressed data in the GZIP file format. 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. ObjectOutputStream An ObjectOutputStream writes primitive data types and graphs of Java objects to an OutputStream. OutputStreamWriter An OutputStreamWriter is a bridge from character streams to byte streams: Characters written to it are encoded into bytes using a specified . ParcelFileDescriptor.AutoCloseOutputStream An OutputStream you can create on a ParcelFileDescriptor, which will take care of calling android. PipedOutputStream A piped output stream can be connected to a piped input stream to create a communications pipe. PipedWriter Piped character-output streams. 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. StringWriter A character stream that collects its output in a string buffer, which can then be used to construct a string. ZipOutputStream This class implements an output stream filter for writing files in the ZIP file format.

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.
