Method Detail

read

public int read(byte[] b)
         throws IOException

Reads up to len bytes of data from the input stream into an array of bytes. An attempt is made to read as many as len bytes, but a smaller number may be read. The number of bytes actually read is returned as an integer.

Overrides:

read in class InputStream

Parameters:

b - The buffer into which the data is 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.

Throws:

IOException
