Constructor Detail

ArgumentParser

public ArgumentParser(java.lang.String[] args)

Initializes the command line argument parser based on the command line arguments. By default, we consider two cases: 1. An option, which starts with a - or a /, followed by the name of the option, a space and the value. For example: -jasmine vm://eventSwitch In that case, getOption("jasmine").equals("vm://eventSwitch"). 2. A parameter, which only sets a certain property. For example: poll In that case, hasParameter("poll") == true.

Parameters:

args - Arguments passed to main(String[]).
