class:BufferedOutputStream [CHANGED]
  • All Implemented Interfaces:
    Closeable, Flushable, AutoCloseable 

    public class BufferedOutputStream
extends FilterOutputStream
    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.
    Since:
    JDK11.0
  • All Implemented Interfaces:

    public class BufferedOutputStream
extends FilterOutputStream
    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.
    Since:
    JDK1.0

    public class BufferedOutputStream
extends FilterOutputStream
    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.
    Since:
    1.0

field:buf [NONE]

  • buf

    protected byte[] buf
    The internal buffer where data is stored.

field:count [NONE]

  • count

    protected int count
    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.

constructor:BufferedOutputStream(java.io.OutputStream) [NONE]

  • BufferedOutputStream

    public BufferedOutputStream(OutputStream out)
    Creates a new buffered output stream to write data to the specified underlying output stream.
    Parameters:
    out - the underlying output stream.

constructor:BufferedOutputStream(java.io.OutputStream, int) [NONE]

  • BufferedOutputStream

    public BufferedOutputStream(OutputStream out,
                            int size)
    Creates a new buffered output stream to write data to the specified underlying output stream with the specified buffer size.
    Parameters:
    out - the underlying output stream.
    size - the buffer size.
    Throws:
    IllegalArgumentException - if size <= 0.

method:write(int) [NONE]

  • write

    public void write(int b)
           throws IOException
    Writes the specified byte to this buffered output stream.
    Overrides:
    write in class FilterOutputStream
    Parameters:
    b - the byte to be written.
    Throws:
    IOException - if an I/O error occurs.

method:write(byte[], int, int) [NONE]

  • write

    public void write(byte[] b,
                  int off,
                  int len)
           throws IOException
    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.

    Overrides:
    write in class FilterOutputStream
    Parameters:
    b - the data.
    off - the start offset in the data.
    len - the number of bytes to write.
    Throws:
    IOException - if an I/O error occurs.

    FilterOutputStream.write(int)

method:flush() [NONE]
