Known Indirect Subclasses

BufferedOutputStream, CheckedOutputStream, CipherOutputStream, DataOutputStream, DeflaterOutputStream, DigestOutputStream, GZIPOutputStream, JarOutputStream, ParcelFileDescriptor.AutoCloseOutputStream, PrintStream, ZipOutputStream

Summary

Public Constructors

					OutputStream()
					Default constructor.

Public Methods

	void	close()
		Close this OutputStream.
	void	flush()
		Flush this OutputStream.
	void	write(byte[] buffer)
		Writes the entire contents of the byte array `buffer` to this OutputStream.
abstract	void	write(int oneByte)
		Writes the specified byte `oneByte` to this OutputStream.
	void	write(byte[] buffer, int offset, int count)
		Writes `count` `bytes` from the byte array `buffer` starting at `offset` to this OutputStream.

Methods inherited from class java.lang.Object

clone, equals, finalize, getClass, hashCode, notify, notifyAll, toString, wait, wait, wait

	Object	clone()
		Answers a new instance of the same class as the receiver, whose slots have been filled in with the values in the slots of the receiver.
	boolean	equals(Object o)
		Compares the argument to the receiver, and answers true if they represent the same object using a class specific comparison.
	void	finalize()
		Called by the virtual machine when there are no longer any (non-weak) references to the receiver.
final	Class	getClass()
		Answers the unique instance of java.lang.Class which represents the class of the receiver.
	int	hashCode()
		Answers an integer hash code for the receiver.
final	void	notify()
		Causes one thread which is `wait` ing on the receiver to be made ready to run.
final	void	notifyAll()
		Causes all threads which are `wait` ing on the receiver to be made ready to run.
	String	toString()
		Answers a string containing a concise, human-readable description of the receiver.
final	void	wait(long time, int frac)
		Causes the thread which sent this message to be made not ready to run either pending some change in the receiver (as indicated by `notify` or `notifyAll`) or the expiration of the timeout.
final	void	wait(long time)
		Causes the thread which sent this message to be made not ready to run either pending some change in the receiver (as indicated by `notify` or `notifyAll`) or the expiration of the timeout.
final	void	wait()
		Causes the thread which sent this message to be made not ready to run pending some change in the receiver (as indicated by `notify` or `notifyAll`).

Public Constructors

public OutputStream()

Default constructor.

Public Methods

public void close()

Close this OutputStream. Concrete implementations of this class should free any resources during close. This implementation does nothing.

Throws

IOException	If an error occurs attempting to close this OutputStream.

public void flush()

Flush this OutputStream. Concrete implementations of this class should ensure any pending writes to the underlying stream are written out when this method is envoked. This implementation does nothing.

Throws

IOException	If an error occurs attempting to flush this OutputStream.

public void write(byte[] buffer)

Writes the entire contents of the byte array buffer to this OutputStream.

Parameters

buffer	the buffer to be written

Throws

IOException	If an error occurs attempting to write to this OutputStream.

public abstract void write(int oneByte)

Writes the specified byte oneByte to this OutputStream. Only the low order byte of oneByte is written.

Parameters

oneByte	the byte to be written

Throws

IOException	If an error occurs attempting to write to this OutputStream.

public void write(byte[] buffer, int offset, int count)

Writes count bytes from the byte array buffer starting at offset to this OutputStream.

Parameters

buffer	the buffer to be written
offset	offset in buffer to get bytes
count	number of bytes in buffer to write

Throws

IOException	If an error occurs attempting to write to this OutputStream.
IndexOutOfBoundsException	If offset or count are outside of bounds.

Parameters

Parameters

Throws

ByteArrayOutputStream	ByteArrayOutputStream is a class whose underlying stream is represented by a byte array.
ChunkedOutputStream	Implements chunked transfer coding.
ContentLengthOutputStream	A stream wrapper that closes itself after a defined number of bytes.
FileOutputStream	FileOutputStream is a class whose underlying stream is represented by a file in the operating system.
FilterOutputStream	FilteredOutputStream is a class which takes an output stream and filters the output in some way.
IdentityOutputStream	A stream for writing with an "identity" transport encoding.
ImageOutputStreamWrapper
ObjectOutputStream	An ObjectOutputStream can be used to save Java objects into a stream where the objects can be loaded later with an ObjectInputStream.
PipedOutputStream	PipedOutputStream is a class which places information on a communications pipe.

BufferedOutputStream	BufferedOutputStream is a class which takes an output stream and buffers the writes to that stream.
CheckedOutputStream	The CheckedOutputStream class is used to maintain a running Checksum of all data written to a stream.
CipherOutputStream
DataOutputStream	DataOutputStream is a filter class which can write typed data to a Stream.
DeflaterOutputStream	The DeflaterOutputStream class implements a stream filter for the writing of compressed data to a stream.
DigestOutputStream
GZIPOutputStream	The GZIPOutputStream class is used to write data to a stream in the GZIP storage format.
JarOutputStream	The JarOutputStream is used to output data in JarFile format.
ParcelFileDescriptor.AutoCloseOutputStream	An OutputStream you can create on a ParcelFileDescriptor, which will take care of calling ParcelFileDescritor.close() for you when the stream is closed.
PrintStream	PrintStream is a class which takes an OutputStream and provides convenience methods for printing common data types in a human readable format on the stream.
ZipOutputStream	ZipOutputStream is used to write ZipEntries to the underlying stream.

				void	flush()
					Flushes the object by writing out any buffered data to the underlying output.

				void	close()
					Close the object and release any system resources it holds.


e.g. "intent" or "activity"
