take the following arguments, depending on the subclass:
-
path For FileOutputStream, a character file name
-
initial_capacity For BufferOutputStream, the size in bytes of the
buffer.
Methods
-
$tell(): return the position in the stream
-
$close(): close the stream
-
$write(x): send x to the stream
-
$capacity(): for BufferOutputStream
-
$finish(): for BufferOutputStream
-
