BufferedOutputStream
open class BufferedOutputStream : FilterOutputStream
kotlin.Any | |||
↳ | java.io.OutputStream | ||
↳ | java.io.FilterOutputStream | ||
↳ | java.io.BufferedOutputStream |
The class implements a buffered output stream. By setting up such an output stream, an application can write bytes to the underlying output stream without necessarily causing a call to the underlying system for each byte written.
Summary
Public constructors | |
---|---|
BufferedOutputStream(out: OutputStream!) Creates a new buffered output stream to write data to the specified underlying output stream. |
|
BufferedOutputStream(out: OutputStream!, size: Int) Creates a new buffered output stream to write data to the specified underlying output stream with the specified buffer size. |
Public methods | |

Public constructors
BufferedOutputStream
BufferedOutputStream(out: OutputStream!)
Creates a new buffered output stream to write data to the specified underlying output stream.
Parameters | |
---|---|
out |
OutputStream!: the underlying output stream. |
BufferedOutputStream
BufferedOutputStream(
out: OutputStream!,
size: Int)
Creates a new buffered output stream to write data to the specified underlying output stream with the specified buffer size.
Parameters | |
---|---|
out |
OutputStream!: the underlying output stream. |
size |
Int: the buffer size. |
Exceptions | |
---|---|
java.lang.IllegalArgumentException |
if size <= 0. |
Public methods
flush
open fun flush(): Unit
Flushes this buffered output stream. This forces any buffered output bytes to be written out to the underlying output stream.
Exceptions | |
---|---|
java.io.IOException |
if an I/O error occurs. |
See Also
write
open fun write(b: Int): Unit
Writes the specified byte to this buffered output stream.
Parameters | |
---|---|
b |
Int: the byte to be written. |
Exceptions | |
---|---|
java.io.IOException |
if an I/O error occurs. |
write
open fun write(
b: ByteArray!,
off: Int,
len: Int
): Unit
Writes len
bytes from the specified byte array starting at offset off
to this buffered output stream.
Ordinarily this method stores bytes from the given array into this stream's buffer, flushing the buffer to the underlying output stream as needed. If the requested length is at least as large as this stream's buffer, however, then this method will flush the buffer and write the bytes directly to the underlying output stream. Thus redundant BufferedOutputStream
s will not copy data unnecessarily.
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. |
Properties
count
protected var count: Int
The number of valid bytes in the buffer. This value is always in the range 0
through buf.length
; elements buf[0]
through buf[count-1]
contain valid byte data.
