Examples of java.io.InputStream.mark()

java.io.InputStream.mark()
Set a Mark position in this InputStream. The parameter readLimit indicates how many bytes can be read before a mark is invalidated. Sending reset() will reposition the Stream back to the marked position provided readLimit has not been surpassed.
This default implementation does nothing and concrete subclasses must provide their own implementations. @param readlimit the number of bytes to be able to read before invalidating the mark.
