read

public int read(byte[] b, int off, int len)

Reads from the Reader into a byte array

Parameters: b the byte array to read into off the offset in the byte array len the length in the byte array to fill

Returns: the actual number read into the byte array, -1 at the end of the stream

Throws: IOException if an error occurs

reset
