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()` Closes this output stream and releases any system resources associated with the stream.
open Unit	`write(b: ByteArray!, off: Int, len: Int)` Writes `len` bytes from the specified `byte` array starting at offset `off` to this output stream.
open Unit	`write(b: Int)` Writes the specified `byte` to this output stream.

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.

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

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.

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

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`	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.

write

Added in API level 8

open fun write(b: Int): Unit

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`.

Exceptions
`java.io.IOException`	if an I/O error occurs.
