Examples of java.io.BufferedReader.mark()

java.io.BufferedReader.mark()
Set a Mark position in this BufferedReader. The parameter readLimit indicates how many characters can be read before a mark is invalidated. Sending reset() will reposition the reader back to the marked position provided readLimit has not been surpassed. @param readlimit an int representing how many characters must be read before invalidating the mark. @throws IOException If an error occurs attempting mark this BufferedReader. @throws IllegalArgumentException If readlimit is < 0
