writeback to summary
public void write(byte[] buf, int off, int len) throws IOException

Overrides java.io.OutputStream.write.

Doc from java.io.OutputStream.write.

Writes len bytes from the specified byte array starting at offset off to this output stream. The general contract for write(b, off, len) is that some of the bytes in the array b are written to the output stream in order; element b[off] is the first byte written and b[off+len-1] is the last byte written by this operation.

If b is null, a NullPointerException is thrown.

If off is negative, or len is negative, or off+len is greater than the length of the array b, then an IndexOutOfBoundsException is thrown.

Parameters
buf:byte[]

the data.

off:int

the start offset in the data.

len:int

the number of bytes to write.

Exceptions
IOException:
if an I/O error occurs. In particular, an IOException is thrown if the output stream is closed.
writeback to summary
public void write(int b) throws IOException

Implements abstract java.io.OutputStream.write.

Doc from java.io.OutputStream.write.

Writes the specified byte to this output stream. The general contract for write is that one byte is written to the output stream. The byte to be written is the eight low-order bits of the argument b. The 24 high-order bits of b are ignored.

Parameters
b:int

the byte.

Exceptions
IOException:
if an I/O error occurs. In particular, an IOException may be thrown if the output stream has been closed.
