| Method Summary | |
| public int | read()
Reads the next byte of data from this input stream. | | public int | read(byte b, int off, int len)
Reads up to len bytes of data from this input stream
into an array of bytes. | | public long | skip(long n)
Skips over and discards n bytes of data from the
input stream. |
| INIT | | final static int INIT(Code) | | |
| read | | public int read() throws IOException(Code) | | 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 DotStuffInputStream
returns -1 when the characteristic 'single dot on a line by itself'
end signature, and removes all leading dots otherwise.
the next byte of data, or -1 if the end of thestream is reached.
exception:
IOException - if an I/O error occurs. |
| read | | public int read(byte b, int off, int len) throws IOException(Code) | | Reads up to len bytes of data from this input stream
into an array of bytes. This method blocks until some input is
available.
Parameters:
b - the buffer into which the data is read.
Parameters:
off - the start offset of the data.
Parameters:
len - the maximum number of bytes read. the total number of bytes read into the buffer, or-1 if there is no more data because the end ofthe stream has been reached.
exception:
IOException - if an I/O error occurs. |
| skip | | public long skip(long n) throws IOException(Code) | | Skips over and discards n bytes of data from the
input stream. The skip method may, for a variety of
reasons, end up skipping over some smaller number of bytes,
possibly 0. The actual number of bytes skipped is
returned.
Parameters:
n - the number of bytes to be skipped. the actual number of bytes skipped.
exception:
IOException - if an I/O error occurs. |
