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

Creates a new buffered output stream to write data to the specified underlying output stream.

Creates a new buffered output stream to write data to the specified underlying output stream with the specified buffer size.

Public methods
open Unit

Flushes this buffered output stream.

open Unit
write(b: Int)

Writes the specified byte to this buffered output stream.

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

Writes len bytes from the specified byte array starting at offset off to this buffered output stream.

Inherited functions
Properties
ByteArray!

The internal buffer where data is stored.

Int

The number of valid bytes in the buffer.

BufferedOutputStream

Added in API level 1
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

Added in API level 1
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

Added in API level 1
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.

write

Added in API level 1
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

Added in API level 1
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 BufferedOutputStreams 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

buf

Added in API level 1
protected var buf: ByteArray!

The internal buffer where data is stored.

count

Added in API level 1
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.
