Method Detail

write

public abstract void write(int b)

Writes a byte. This method will block until the byte is actually written.

Parameters:

b - the byte

Throws:

IOException - If an I/O error has occurred.

write

public void write(byte[] b)
           throws IOException

Writes an array of bytes. This method will block until the bytes are actually written.

Parameters:

b - the data to be written

Throws:

IOException - If an I/O error has occurred.

write

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

Writes a sub array of bytes.

Parameters:

b - the data to be written

off - the start offset in the data

len - the number of bytes that are written

Throws:

IOException - If an I/O error has occurred.

flush

public void flush()
           throws IOException

Flushes the stream. This will write any buffered output bytes.

Throws:

IOException - If an I/O error has occurred.
