Constructor Detail

SwitchArg

public SwitchArg(int arg,
                 Map<String,Statement> valueToActions)

Generates a switch statement based on arg. If its value is found to be a key in valueToActions, the corresponding action is invoked.

Ex. arg is 1 - the first argument to the script
and valueToActions is {"start" -> "echo hello", "stop" -> "echo goodbye"}
the script created will respond accordingly:
./script start
<< returns hello
./script stop
<< returns goodbye

Parameters:

arg - - shell arg to switch on

valueToActions - - case statements, if the value of the arg matches a key, the corresponding value will be invoked.
