public int read() throws IOException
Returns
the next byte of data, or -1 if the end of the
stream has been reached.
Description
Reads the next byte of data from this input stream. The value
byte is returned as an int in the range
0 to 255. If no byte is available
because the end of the stream has been reached, the value
-1 is returned. This method blocks until input data
is available, the end of the stream is detected, or an exception
is thrown.
This method returns the most recently pushed-back byte, if there is
one, and otherwise calls the read method of its underlying
input stream and returns whatever value that method returns.
Exceptions
IOException
if an I/O error occurs.
Overrides
read in class FilterInputStream

public int read( byte b[],
int off,
int len ) throws IOException
Parameters
- b
- the buffer into which the data is read.
- off
- the start offset of the data.
- len
- the maximum number of bytes read.
Returns
the total number of bytes read into the buffer, or
-1 if there is no more data because the end of
the stream has been reached.
Description
Reads up to len bytes of data from this input stream into
an array of bytes. This method first reads any pushed-back bytes; after
that, if fewer than than len bytes have been read then it
reads from the underlying input stream. This method blocks until at
least 1 byte of input is available.
Exceptions
IOException
if an I/O error occurs.
Overrides
read in class FilterInputStream
