Base64OutputStream


open class Base64OutputStream : FilterOutputStream

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

Summary

Public constructors

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

Public methods
open Unit

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

open Unit
write(b: Int)

Inherited functions
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.

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.

Inherited properties
OutputStream! out

The underlying output stream to be filtered.

Public constructors

Base64OutputStream

Added in API level 8
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

Added in API level 8
open fun close(): Unit
Exceptions
java.lang.Exception if this resource cannot be closed
java.io.IOException if an I/O error occurs.

write

Added in API level 8
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

Added in API level 8
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.
