Method Detail

opt

public CLI.CLIBuilder opt(String shortName,

longName - the multi character name of the option (no -- characters proceed it).

defaultValue - the value that will be returned of the command if none is given. null if none is given.

Returns:

a builder to be used to continue creating the command line.
