  • Constructor Details

  • Method Details

    • makeInternalManager

      protected AbstractManager<Turnout> makeInternalManager()
      Description copied from class: AbstractProxyManager
      Create specific internal manager as needed for concrete type.
      Specified by:
      makeInternalManager in class AbstractProxyManager<Turnout>
      Returns:
      an internal manager

    • addManager

      public void addManager(@Nonnull Manager<Turnout> m)
      Add a Manager to the collection of Managers.
      Specified by:
      addManager in interface ProxyManager<Turnout>
      Overrides:
      addManager in class AbstractProxyManager<Turnout>
      Parameters:
      m - the Manager to add; if manager has already been added, it will not be added again

    • getTurnout

      public Turnout getTurnout(@Nonnull String name)
      Locate via user name, then system name if needed.
      Specified by:
      getTurnout in interface TurnoutManager
      Parameters:
      name - User name or system name to match
      Returns:
      Null if nothing by that name exists

    • makeBean

      @Nonnull protected Turnout makeBean(Manager<Turnout> manager, String systemName, String userName) throws IllegalArgumentException
      Defer creation of the proper type to the subclass.
      Specified by:
      makeBean in class AbstractProvidingProxyManager<Turnout>
      Parameters:
      manager - the manager to invoke
      systemName - the system name
      userName - the user name
      Returns:
      a bean
      Throws:
      IllegalArgumentException - if unable to make.

    • provideTurnout

      @Nonnull public Turnout provideTurnout(@Nonnull String name) throws IllegalArgumentException
      Get the Turnout with the user name, then system name if needed; if that fails, create a new Turnout. If the name is a valid system name, it will be used for the new Turnout. Otherwise, the Manager.makeSystemName(java.lang.String) method will attempt to turn it into a valid system name.

      This provides the same function as ProvidingManager.provide(java.lang.String) which has a more generic form.

      Specified by:
      provideTurnout in interface TurnoutManager
      Parameters:
      name - User name, system name, or address which can be promoted to system name
      Returns:
      Never null
      Throws:
      IllegalArgumentException - if Turnout doesn't already exist and the manager cannot create the Turnout due to an illegal name or name that can't be parsed.

    • provide

      @Nonnull public Turnout provide(@Nonnull String name) throws IllegalArgumentException
      Get an existing instance via user name, then system name; if no matching instance is found, create a new NameBean from the system name.

      If the name is a valid system name, it will be used for the new NamedBean. Otherwise, the Manager.makeSystemName(java.lang.String) method will attempt to turn it into a valid system name which the manager will attempt to use. If that fails, an exception is thrown.

      This is similar to the specific methods found in certain type-specific managers: TurnoutManager.provideTurnout(java.lang.String), SensorManager.provideSensor(java.lang.String), et al. Those might be more mnemonic; this one is more generic. Neither is preferred nor deprecated; use your choice.

      Specified by:
      provide in interface ProvidingManager<Turnout>
      Specified by:
      provide in interface TurnoutManager
      Parameters:
      name - User name, system name, or address which can be promoted to system name
      Returns:
      Never null
      Throws:
      IllegalArgumentException - if NamedBean doesn't already exist and the manager cannot create it due to an illegal name or name that can't be parsed.

    • newTurnout

      @Nonnull public Turnout newTurnout(@Nonnull String systemName, String userName) throws IllegalArgumentException
      Get an instance with the specified system and user names. Note that two calls with the same arguments will get the same instance; there is only one Sensor object representing a given physical turnout and therefore only one with a specific system or user name.

      This will always return a valid object reference for a valid request; a new object will be created if necessary. In that case:

      • If a null reference is given for user name, no user name will be associated with the Turnout object created; a valid system name must be provided
      • If a null reference is given for the system name, a system name will _somehow_ be inferred from the user name. How this is done is system specific. Note: a future extension of this interface will add an exception to signal that this was not possible.
      • If both names are provided, the system name defines the hardware access of the desired turnout, and the user address is associated with it.
      Note that it is possible to make an inconsistent request if both addresses are provided, but the given values are associated with different objects. This is a problem, and we don't have a good solution except to issue warnings. This will mostly happen if you're creating Sensors when you should be looking them up.
      Specified by:
      newTurnout in interface TurnoutManager
      Parameters:
      systemName - the system name
      userName - the user name (optional)
      Returns:
      requested Turnout object (never null)
      Throws:
      IllegalArgumentException - if cannot create the Turnout; likely due to an illegal name or name that cannot be parsed

    • getClosedText

      @Nonnull public String getClosedText()
      Get text to be used for the Turnout.CLOSED state in user communication. Allows text other than "CLOSED" to be use with certain hardware system to represent the Turnout.CLOSED state. Defaults to the primary manager. This means that the primary manager sets the terminology used. Note: the primary manager need not override the method in AbstractTurnoutManager if "CLOSED" is the desired terminology.
      Specified by:
      getClosedText in interface TurnoutManager
      Returns:
      the textual representation of Turnout.CLOSED

    • getThrownText

      @Nonnull public String getThrownText()
      Get text to be used for the Turnout.THROWN state in user communication. Allows text other than "THROWN" to be use with certain hardware system to represent the Turnout.THROWN state. Defaults to the primary manager. This means that the primary manager sets the terminology used. Note: the primary manager need not override the method in AbstractTurnoutManager if "THROWN" is the desired terminology.
      Specified by:
      getThrownText in interface TurnoutManager
      Returns:
      the textual representation of Turnout.THROWN

    • askNumControlBits

      public int askNumControlBits(@Nonnull String systemName)
      Get from the user, the number of addressed bits used to control a turnout. Normally this is 1, and the default routine returns 1 automatically. Turnout Managers for systems that can handle multiple control bits should override this method with one which asks the user to specify the number of control bits. If the user specifies more than one control bit, this method should check if the additional bits are available (not assigned to another object). If the bits are not available, this method should return 0 for number of control bits, after informing the user of the problem.
      Specified by:
      askNumControlBits in interface TurnoutManager
      Parameters:
      systemName - the turnout system name
      Returns:
      the bit length for turnout control

    • askControlType

      public int askControlType(@Nonnull String systemName)
      Get from the user, the type of output to be used bits to control a turnout. Normally this is 0 for 'steady state' control, and the default routine returns 0 automatically. Turnout Managers for systems that can handle pulsed control as well as steady state control should override this method with one which asks the user to specify the type of control to be used. The routine should return 0 for 'steady state' control, or n for 'pulsed' control, where n specifies the duration of the pulse (normally in seconds).
      Specified by:
      askControlType in interface TurnoutManager
      Parameters:
      systemName - the turnout system name
      Returns:
      0 for steady state or the number of seconds for a pulse control

    • isControlTypeSupported

      public boolean isControlTypeSupported(@Nonnull String systemName)
      Determine if the manager supports the handling of pulsed and steady state control as the TurnoutManager.askControlType(java.lang.String) will always return a value even if it is not supported.
      Specified by:
      isControlTypeSupported in interface TurnoutManager
      Parameters:
      systemName - the turnout system name
      Returns:
      true if manager supports the control type returned by TurnoutManager.askControlType(java.lang.String); false otherwise

    • isNumControlBitsSupported

      public boolean isNumControlBitsSupported(@Nonnull String systemName)
      Determine if the manager supports multiple control bits, as TurnoutManager.askNumControlBits(java.lang.String) will always return a value even if it is not supported.
      Specified by:
      isNumControlBitsSupported in interface TurnoutManager
      Parameters:
      systemName - the turnout system name
      Returns:
      true if manager supports multiple control bits for the turnout; false otherwise

    • getValidOperationTypes

      @Nonnull public String[] getValidOperationTypes()
      Get a list of the valid TurnoutOperation subtypes for use with turnouts of this system.
      Specified by:
      getValidOperationTypes in interface TurnoutManager
      Returns:
      a list of subtypes or an empty list if turnout operations are not supported

    • allowMultipleAdditions

      public boolean allowMultipleAdditions(@Nonnull 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.

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

      JmriException

    • setDefaultThrownSpeed

      public void setDefaultThrownSpeed(@Nonnull String speed) throws JmriException
      Specified by:
      setDefaultThrownSpeed in interface TurnoutManager

      outputInterval from default TurnoutManager

    • setOutputInterval

      public void setOutputInterval(int newInterval)
      Set the Interval (in ms) to wait between output commands. This method is only used in jmri.jmrix.internal.InternalTurnoutManagerTest and should not be used in actual code, as it can overwrite individual per connection values set by the user.

    • getXMLOrder

      public int getXMLOrder()
      Determine the order that types should be written when storing panel files. Uses one of the constants defined in this class.

      Yes, that's an overly-centralized methodology, but it works for now.

      Specified by:
      getXMLOrder in interface Manager<Turnout>
      Returns:
      write order for this Manager; larger is later.

    • getBeanTypeHandled

      @Nonnull public String getBeanTypeHandled(boolean plural)

      For instance, in the code where we are dealing with just a bean and a message that needs to be passed to the user or in a log.

      Specified by:
      getBeanTypeHandled in interface Manager<Turnout>
      Parameters:
      plural - true to return plural form of the type; false to return singular form
      Returns:
      a string of the bean type that the manager handles, eg Turnout, Sensor etc

    • getNamedBeanClass

      public Class<Turnout> getNamedBeanClass()
