Base64OutputStream

Kotlin |Java

open class Base64OutputStream : FilterOutputStream

kotlin.Any
↳	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

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

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: 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.

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.
