      • createNewLight

        @Nonnull
protected Light createNewLight​(@Nonnull
                               java.lang.String systemName,
                               java.lang.String userName)
                        throws java.lang.IllegalArgumentException
        Internal method to invoke the factory, after all the logic for returning an existing method has been invoked.
        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:
        never null
        Throws:
        java.lang.IllegalArgumentException

      • 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

      • validateSystemNameFormat

        @Nonnull
public java.lang.String validateSystemNameFormat​(@Nonnull
                                                 java.lang.String name,
                                                 @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:
        name - 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

      • createSystemName

        public java.lang.String createSystemName​(@Nonnull
                                         java.lang.String curAddress,
                                         @Nonnull
                                         java.lang.String prefix)
                                  throws JmriException
        Create a System Name from hardware address and system letter prefix. AbstractManager performs no validation.
        Specified by:
        createSystemName in interface LightManager
        Overrides:
        createSystemName in class AbstractManager<Light>
        Parameters:
        curAddress - hardware address, no system prefix or type letter.
        prefix - - just system prefix, not including Type Letter.
        Returns:
        full system name with system prefix, type letter and hardware address.
        Throws:
        JmriException - if unable to create a system name.

      • validSystemNameConfig

        public boolean validSystemNameConfig​(@Nonnull
                                     java.lang.String systemName)
        Test if parameter is a valid system name for current configuration.
        Parameters:
        systemName - the system name
        Returns:
        true if valid; false otherwise

      • getNextValidSystemName

        @Nonnull
@CheckReturnValue
public java.lang.String getNextValidSystemName​(@Nonnull
                                               NamedBean currentBean)
                                        throws JmriException
        Description copied from interface: NameIncrementingManager
        Get the next valid NamedBean system name.

        For example, if the system name of the provided NamedBean is IS10, the next valid name is IS11.

        This should not be called if NameIncrementingManager.allowMultipleAdditions(java.lang.String) returns false.

        Pays no attention to whether the next NamedBean already exists or not, just works out the name. Nor is there any guarantee that the return value can actually be created: a provide() call on the return value can still perhaps fail in some circumstances.

        In some cases, there is no clear next address. In that case, a JmriException is thrown. For example, some systems have no concept of a "next" address; Internal sensors don't necessarily have numeric suffixes; etc.

        Default implementation works for names of the form (prefix)(type letter)(numeric string) by incrementing the numeric string as needed.

        Parameters:
        currentBean - The NamedBean who's system name that provides the base for "next"
        Returns:
        The next valid system name
        Throws:
        JmriException - If unable to create a valid next address
