public class Base64OutputStream
extends FilterOutputStream

java.lang.Object
   ↳ java.io.OutputStream
     ↳ java.io.FilterOutputStream
       ↳ android.util.Base64OutputStream


An OutputStream that does Base64 encoding on the data written to it, writing the resulting data to another OutputStream.

Summary

Inherited fields

protected OutputStream out

The underlying output stream to be filtered.

Public constructors

Base64OutputStream(OutputStream out, int flags)

Performs Base64 encoding on the data written to the stream, writing the encoded data to another OutputStream.

Public methods

void close()

Closes this output stream and releases any system resources associated with the stream.

void write(byte[] b, int off, int len)

Writes len bytes from the specified byte array starting at offset off to this output stream.

void write(int b)

Writes the specified byte to this output stream.

Inherited methods

void close()

Closes this output stream and releases any system resources associated with the stream.

void flush()

Flushes this output stream and forces any buffered output bytes to be written out to the stream.

void write(byte[] b)

Writes b.length bytes to this output stream.

void write(byte[] b, int off, int len)

Writes len bytes from the specified byte array starting at offset off to this output stream.

void write(int b)

Writes the specified byte to this output stream.

void close()

Closes this output stream and releases any system resources associated with this stream.

void flush()

Flushes this output stream and forces any buffered output bytes to be written out.

static OutputStream nullOutputStream()

Returns a new OutputStream which discards all bytes.

void write(byte[] b)

Writes b.length bytes from the specified byte array to this output stream.

void write(byte[] b, int off, int len)

Writes len bytes from the specified byte array starting at offset off to this output stream.

abstract void write(int b)

Writes the specified byte to this output stream.

Object clone()

Creates and returns a copy of this object.

boolean equals(Object obj)

Indicates whether some other object is "equal to" this one.

void finalize()

Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.

final Class<?> getClass()

Returns the runtime class of this Object.

int hashCode()

Returns a hash code value for the object.

final void notify()

Wakes up a single thread that is waiting on this object's monitor.

final void notifyAll()

Wakes up all threads that are waiting on this object's monitor.

String toString()

Returns a string representation of the object.

final void wait(long timeoutMillis, int nanos)

Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.

final void wait(long timeoutMillis)

Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.

final void wait()

Causes the current thread to wait until it is awakened, typically by being notified or interrupted.

abstract void close()

Closes this stream and releases any system resources associated with it.

abstract void flush()

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

abstract void close()

Closes this resource, relinquishing any underlying resources.

Public constructors

Base64OutputStream

Added in API level 8
public Base64OutputStream (OutputStream out, 
                int flags)

Performs Base64 encoding on the data written to the stream, writing the encoded data to another OutputStream.

Parameters
out OutputStream: the OutputStream to write the encoded data to

flags int: bit flags for controlling the encoder; see the constants in Base64

Public methods

close

Added in API level 8
public void close ()

Closes this output stream and releases any system resources associated with the stream.

When not already closed, the close method of FilterOutputStream calls its flush method, and then calls the close method of its underlying output stream.

Throws
IOException

write

Added in API level 8
public void write (byte[] b, 
                int off, 
                int len)

Writes len bytes from the specified byte array starting at offset off to this output stream.

The write method of FilterOutputStream calls the write method of one argument on each byte to output.

Note that this method does not call the write method of its underlying output stream with the same arguments. Subclasses of FilterOutputStream should provide a more efficient implementation of this method.

Parameters
b byte: the data.

off int: the start offset in the data.

len int: the number of bytes to write.

Throws
IOException

write

Added in API level 8
public void write (int b)

Writes the specified byte to this output stream.

The write method of FilterOutputStream calls the write method of its underlying output stream, that is, it performs out.write(b).

Implements the abstract write method of OutputStream.

Parameters
b int: the byte.

Throws
IOException
