public static MyCommandLineParameters getCommandLineParameters(java.lang.String[] args,
                                                               java.lang.String defaultPropertyName,
                                                               java.util.Properties defaultProperties)

Gets a Properties object representing the contents of the command line parameters, with the defaults for the specifyable options held in the given defaultProperties.

Command line parameters can be specified using two syntaxes :

1. optionName(optionValue)
2. -optionName:OptionValue

There is one option that can be declared the default option. The value for this option can be specified without specifying the option name. E.g. if the default option is FILE, then the following command lines are equivalent :

1. java JavaMainClass optionValue
2. java JavaMainClass FILE(optionValue)
3. java JavaMainClass -FILE:optionValue

Parameters:

args - The command line parameters in String[] format

defaultPropertyName - The name of the property that must not be typed, or null if there is no default property

defaultProperties - The Properties object containing the defaults for the options specifyable through the command line, or null if there are no defaults

Returns:

A parameter map representing the contents of the command line parameters
