CheckedOutputStream

open class CheckedOutputStream : FilterOutputStream

An output stream that also maintains a checksum of the data being written. The checksum can then be used to verify the integrity of the output data.

Summary

Public constructors

Creates an output stream with the specified Checksum.

Public methods
open Checksum!

Returns the Checksum for this output stream.

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

Writes an array of bytes.

open Unit
write(b: Int)

Writes a byte.

Inherited functions
Unit 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.

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

CheckedOutputStream

Added in API level 1
CheckedOutputStream(
    out: OutputStream!,
    cksum: Checksum!)

Creates an output stream with the specified Checksum.

Parameters
out OutputStream!: the output stream
cksum Checksum!: the checksum

Public methods

getChecksum

Added in API level 1
open fun getChecksum(): Checksum!

Returns the Checksum for this output stream.

Return
Checksum! the Checksum

write

Added in API level 1
open fun write(
    b: ByteArray!,
    off: Int,
    len: Int
): Unit

Writes an array of bytes. Will block until the bytes are actually written.

Parameters
b ByteArray!: the data to be written
off Int: the start offset of the data
len Int: the number of bytes to be written
Exceptions
java.io.IOException if an I/O error has occurred

write

Added in API level 1
open fun write(b: Int): Unit

Writes a byte. Will block until the byte is actually written.

Parameters
b Int: the byte to be written
Exceptions
java.io.IOException if an I/O error has occurred
