Description copied from class: Argument

Sets the default value of this Argument.

Overrides:

setDefaultValue in class Argument

Parameters:

defaultValue - the default value

Returns:

the current Argument instance

setDescription

Description copied from class: Argument

Sets whether or not the current Argument is required.

Overrides:

setRequired in class Argument

Parameters:

required - true to make this argument mandatory, {@link false} otherwise

Returns:
