Known Direct Subclasses |
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.

The internal buffer where data is stored.
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.
Creates a new buffered output stream to write data to the specified underlying output stream.
out | the underlying output stream. |

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

size | the buffer size. |
IllegalArgumentException | if size <= 0. |
---|
Flushes this buffered output stream. This forces any buffered output bytes to be written out to the underlying output stream.
IOException | if an I/O error occurs. |
---|
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

b | the data. |

off | the start offset in the data. |
len | the number of bytes to write. |

Writes the specified byte to this buffered output stream.
