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 |
Writes an array of bytes.
|
open Unit |
Writes a byte.
|
Inherited functions |
From class FilterOutputStream
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 .

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.

CheckedOutputStream
CheckedOutputStream(
out: OutputStream!,
cksum: Checksum!)
Creates an output stream with the specified Checksum.
Public methods
getChecksum
open fun getChecksum(): Checksum!
Returns the Checksum for this output stream.
write
open fun write(
b: ByteArray!,
off: Int,

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
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 |
