public BigInt_input_option(String option,
                           BigInteger_inputs inputs,
                           String argument,
                           String explanation)

Parameters:

option - the literal option string as it will appear on the command line

inputs - the input collection

argument - name of the argument for the explanation

explanation - explanation for the usage information

Method Detail

get_bigint_argument

public BigInteger get_bigint_argument(Commandline cl)

Parse a BigInteger argument from the command line. Tries to convert the next unprocessed command line element to a BigInteger. Displays an error message and terminates the application if there is no next command line element or if it cannot be converted.

Parameters:

cl - command line instance

Returns:

next unprocessed option converted to BigInteger if possible

matched

public void matched(Commandline cl)

Called when this option has been recognized on the command line. Retrives the next command line argument, interprets it as a base 10 BigInteger and stores it in the vector of BigInteger inputs inputs.

Specified by:

matched in class Option

Parameters:

cl - command line instance
