Method Detail

read

public int read()
         throws IOException

Description copied from class: FilterInputStream

Reads a single byte from the filtered stream and returns it as an integer in the range from 0 to 255. Returns -1 if the end of this stream has been reached.

Overrides:

read in class FilterInputStream

Returns:

the byte read or -1 if the end of the filtered stream has been reached.

Throws:

IOException - if the stream is closed or another IOException occurs.

                int off,
                int len)
         throws IOException

Description copied from class: InputStream

Reads up to byteCount bytes from this stream and stores them in the byte array buffer starting at byteOffset. Returns the number of bytes actually read or -1 if the end of the stream has been reached.

Overrides:

read in class FilterInputStream

Throws:

IOException - if the stream is closed or another IOException occurs.
