Examples of com.martiansoftware.jsap.SimpleJSAP

com.martiansoftware.jsap.SimpleJSAP
A simple interface to {@link com.martiansoftware.jsap.JSAP} that handles directly help,explanation and an array of parameters.
More precisely, instances of this class behave exactly like those of {@link com.martiansoftware.jsap.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, {@link #messagePrinted()} will return true, and the caller may check this conditionto stop its actions.
The screen width used to format the help text may be set using {@link #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 Sebastiano Vigna
