      • createNewLight

        @Nonnull
        protected Light createNewLight​(java.lang.String systemName,
                                       java.lang.String userName)
                                throws java.lang.IllegalArgumentException
        Create a new Light based on the system name. Assumes calling method has checked that a Light with this system name does not already exist.
        Specified by:
        createNewLight in class AbstractLightManager
        Parameters:
        systemName - the system name to use for this light
        userName - the user name to use for this light
        Returns:
        null if the system name is not in a valid format
        Throws:
        java.lang.IllegalArgumentException
      • validateSystemNameFormat

        @Nonnull
        public java.lang.String validateSystemNameFormat​(@Nonnull
                                                         java.lang.String systemName,
                                                         @Nonnull
                                                         java.util.Locale locale)
        Validate the format of name, returning it unchanged if valid.

        Although further restrictions may be added by system-specific implementations, at a minimum, the implementation must consider a name that does not start with the System Name prefix for this manager to be invalid, and must consider a name that is the same as the System Name prefix to be invalid.

        Overriding implementations may rely on Manager.validSystemNameFormat(java.lang.String), however they must provide an actionable message in the thrown exception if that method does not return Manager.NameValidity.VALID. When overriding implementations of this method rely on validSystemNameFormat(), implementations of that method must not throw an exception, log an error, or otherwise disrupt the user.

        Parameters:
        systemName - the system name to validate
        locale - the locale for a localized exception; this is needed for the JMRI web server, which supports multiple locales
        Returns:
        the unchanged value of the name parameter
      • getBitFromSystemName

        public int getBitFromSystemName​(java.lang.String systemName)
        Get the bit address from the system name.
        Parameters:
        systemName - a valid Light System Name
        Returns:
        the light number extracted from the system name
      • allowMultipleAdditions

        public boolean allowMultipleAdditions​(@Nonnull
                                              java.lang.String systemName)
        Determines if it is possible to add a range of NamedBeans in numerical order for a particular system implementation.

        Default is not providing this service. Systems should override this method if they do provide the service.

        Parameters:
        systemName - the system name to check against; appears to be ignored in all implementations
        Returns:
        true if possible; false otherwise
