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

From class java.io.FilterOutputStream


    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

From class


        
          java.io.FilterOutputStream

`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.

From class


        
          java.io.OutputStream

`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.

From class


        
          java.lang.Object

`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.

From interface


        
          java.io.Closeable


      close()

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

From interface


        
          java.io.Flushable


      flush()

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

From interface


        
          java.lang.AutoCloseable


      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`
