public int read() throws IOException
Returns
the next byte of data, or -1 if the end of this
stream is 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.
The read method of
LineNumberInputStream calls the read
method of the underlying input stream. It checks for carriage
returns and newline characters in the input, and modifies the
current line number as appropriate. A carriage-return character or
a carriage return followed by a newline character are both
converted into a single newline character.
Exceptions
IOException
if an I/O error occurs.

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
this stream has been reached.
Description
Reads up to len bytes of data from this input stream
into an array of bytes. This method blocks until some input is available.
The read method of
LineNumberInputStream repeatedly calls the
read method of zero arguments to fill in the byte array.
Exceptions
IOException
if an I/O error occurs.
Overrides
read in class FilterInputStream
