public int read(char[] cbuf,
                int off,
                int len)
         throws IOException

Read up to len characters from the stream and put them in cbuf starting at offset off. As characters are read, the following conversions are performed: \\uXXXX is converted to one Unicode character having the value represented by the four hex digits. \\ is converted to \ \X any character preceded by \ is converted to that character.

Overrides:

read in class FilterReader

Parameters:

cbuf - the array of characters that is filled in

off - the offset at which to start placing characters

len - the maximum number of characters to read

Returns:

the number of characters read
