      • constrain

        public void constrain(PasswordGenerator generator)
        Some Rule implementing classes will not have a constraint to impose, in which case method in this class will be called and will do nothing.
        Specified by:
        constrain in interface Rule
        Parameters:
        generator - including a character template to be constrained.

      • validateSafe

        public boolean validateSafe(java.lang.String password,
                            ValidationInfo validationInfo)
        Validate the given password using the given validation info. This version should never throw an exception, but will return false if the password is invalid.
        Specified by:
        validateSafe in interface Rule
        Parameters:
        password - Password to validate.
        validationInfo - contains contextual information about the password being validated.
        Returns:
        true if password is valid, false otherwise.

      • getParameter

        public java.lang.String getParameter()
        This Rule interface method in is not valid in the context of standard rule classes. Each standard rule class has its own method for getting constraining parameter value. RuntimeException is thrown during an attempt to use this interface method because the method is not valid in the context of this class.
        Specified by:
        getParameter in interface Rule
        Returns:
        String value of the parameter.

      • setParameter

        public void setParameter(java.lang.String parameter)
        This Rule interface method in is not valid in the context of standard rule classes. Each standard rule class has its own method for setting constraining parameter value. RuntimeException is thrown during an attempt to use this interface method because the method is not valid in the context of this class.
        Specified by:
        setParameter in interface Rule
        Parameters:
        parameter - String value of the parameter.
