public class SimpleJSAP extends JSAP
A simple interface toJSAP
that handles directly help, explanation and an array of parameters.More precisely, instances of this class behave exactly like those of
JSAP
, but additionally require a command name, an explanation (a wordy description) and an array of parameters (which will be registered automatically). A switch activated by --help is always registered under the ID help.A message will be automatically printed upon invocation of the
parse()
methods if an error occurs, or if the help switch is detected. In this case,messagePrinted()
will return true, and the caller may check this condition to stop its actions.The screen width used to format the help text may be set using
setScreenWidth(int)
. The formatter will preserve newlines. Note: as of 2.0a non-breaking spaces are temporarily disabled until some console encoding issues have been worked out. - ML- Author:
