Base64OutputStream | API reference | Android Developers (original) (raw)

open class Base64OutputStream : FilterOutputStream

kotlin.Any
↳	java.io.OutputStream
	↳	java.io.FilterOutputStream
		↳

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

Summary

Public constructors
Base64OutputStream(out: OutputStream!, flags: Int) Performs Base64 encoding on the data written to the stream, writing the encoded data to another OutputStream.

Public methods
open Unit	close()
open Unit	write(b: ByteArray!, off: Int, len: Int)
open Unit	write(b: Int)

Inherited functions
From class FilterOutputStream Unit flush() Flushes this output stream and forces any buffered output bytes to be written out to the stream. The flush method of FilterOutputStream calls the flush method of its underlying output stream. Unit write(b: ByteArray!) Writes b.length bytes to this output stream. The write method of FilterOutputStream calls its write method of three arguments with the arguments b, 0, and b.length. Note that this method does not call the one-argument write method of its underlying output stream with the single argument b.
From class OutputStream OutputStream! nullOutputStream() Returns a new OutputStream which discards all bytes. The returned stream is initially open. The stream is closed by calling the close() method. Subsequent calls to close() have no effect. While the stream is open, the write(int), write(byte[]), and write(byte[], int, int) methods do nothing. After the stream has been closed, these methods all throw IOException. The flush() method does nothing.

Public constructors

Base64OutputStream

Base64OutputStream(
out: OutputStream!,
flags: Int)

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

open fun close(): Unit

Exceptions
java.lang.Exception	if this resource cannot be closed
java.io.IOException	if an I/O error occurs.

write

open fun write(
    b: ByteArray!,
    off: Int,
    len: Int
): Unit

Parameters
b	ByteArray!: the data.
off	Int: the start offset in the data.
len	Int: the number of bytes to write.

Exceptions
java.io.IOException	if an I/O error occurs. In particular, an IOException is thrown if the output stream is closed.

write

open fun write(b: Int): Unit

Parameters
b	Int: the byte.

Exceptions
java.io.IOException	if an I/O error occurs. In particular, an IOException may be thrown if the output stream has been closed.
