Examples of java.io.Reader.skip()

java.io.Reader.skip()
Skips count number of characters in this Reader. Subsequent read()'s will not return these characters unless reset() is used. This method may perform multiple reads to read count characters. @param count how many characters should be passed over @return how many characters were successfully passed over @throws IOException If the Reader is closed when the call is made or if an IO error occurs during the operation.
