Class OlcbReporterManager

    • Method Detail

      • createNewReporter

        protected Reporter createNewReporter​(@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 Reporter has been invoked.
        Specified by:
        createNewReporter in class AbstractReporterManager
        systemName - system name.
        userName - username.
        never null
        java.lang.IllegalArgumentException - when SystemName can't be converted
      • startLoad

        public void startLoad()
        This function is invoked before an XML load is started. We defer initialization of the newly created Reporters until finishLoad. This avoids certain quadratic run-time operations due to update listeners.
      • finishLoad

        public void finishLoad()
        This function is invoked after the XML load is complete and all Reporters are instantiated and their feedback type is read in. We use this hook to finalize the construction of the OpenLCB objects whose instantiation was deferred until the feedback type was known.
      • allowMultipleAdditions

        public boolean allowMultipleAdditions​(@Nonnull
                                              java.lang.String systemName)
        Description copied from interface: NameIncrementingManager
        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.

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

        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.

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

        public java.lang.String incrementSystemName​(java.lang.String currentName)
        Computes the system name for the next block sensor. This increments the unique ID of the manufacturer-assigned range (bytes 4-5-6) by one.
        currentName - system name for a reporter of a given block
        next block's system name.
      • validateSystemNameFormat

        public java.lang.String validateSystemNameFormat​(@Nonnull
                                                         java.lang.String name,
                                                         java.util.Locale locale)
                                                  throws NamedBean.BadSystemNameException
        Validates to OpenLCB format. 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.

        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
        the unchanged value of the name parameter
        NamedBean.BadSystemNameException - if provided name is an invalid format
