jmri.BlockManager

All Implemented Interfaces:: PropertyChangeListener, VetoableChangeListener, EventListener, PropertyChangeFirer, PropertyChangeProvider, SilenceablePropertyChangeProvider, VetoableChangeFirer, VetoableChangeProvider, InstanceManagerAutoDefault, Manager<Block>, ProvidingManager<Block>

public class BlockManager
extends AbstractManager<Block>
implements ProvidingManager<Block>, InstanceManagerAutoDefault

Basic implementation of a BlockManager.

Note that this does not enforce any particular system naming convention.

Note this is a concrete class, unlike the interface/implementation pairs of most Managers, because there are currently only one implementation for Blocks.

Constructor Details
- BlockManager
  
  public BlockManager()
Method Details
- dispose
  
  public void dispose()
  
  Description copied from class: AbstractManager
  
  Free resources when no longer used. Specifically, remove all references to and from this object, so it can be garbage-collected.
  
  Specified by:
  
  dispose in interface Manager<Block>
  
  Overrides:
  
  dispose in class AbstractManager<Block>
- getXMLOrder
  
  @CheckReturnValue public int getXMLOrder()
  
  Description copied from interface: Manager
  
  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<Block>
  
  Returns:
  
  write order for this Manager; larger is later.
- typeLetter
  
  @CheckReturnValue public char typeLetter()
  
  Specified by:
  
  typeLetter in interface Manager<Block>
  
  Returns:
  
  The type letter for a specific implementation
- getNamedBeanClass
  
  public Class<Block> getNamedBeanClass()
  
  Description copied from interface: Manager
  
  Get the class of NamedBean supported by this Manager. This should be the generic class used in the Manager's class declaration.
  
  Specified by:
  
  getNamedBeanClass in interface Manager<Block>
  
  Returns:
  
  the class supported by this Manager.
- isSavedPathInfo
  
  @CheckReturnValue public boolean isSavedPathInfo()
- setSavedPathInfo
  
  public void setSavedPathInfo(boolean save)
- createNewBlock
  
  @CheckForNull public Block createNewBlock(@Nonnull String systemName, @CheckForNull String userName)
  
  Create a new Block, only if it does not exist.
  
  Parameters:
  
  systemName - the system name
  
  userName - the user name
  
  Returns:
  
  null if a Block with the same systemName or userName already exists, or if there is trouble creating a new Block
- createNewBlock
  
  @CheckForNull public Block createNewBlock(@Nonnull String userName)
  
  Create a new Block using an automatically incrementing system name.
  
  Parameters:
  
  userName - the user name for the new Block
  
  Returns:
  
  null if a Block with the same systemName or userName already exists, or if there is trouble creating a new Block.
- provideBlock
  
  @Nonnull public Block provideBlock(@Nonnull String name)
  
  If the Block exists, return it, otherwise create a new one and return it. If the argument starts with the system prefix and type letter, usually "IB", then the argument is considered a system name, otherwise it's considered a user name and a system name is automatically created.
  
  Parameters:
  
  name - the system name or the user name for the block
  
  Returns:
  
  a new or existing Block
  
  Throws:
  
  IllegalArgumentException - if cannot create block or no name supplied; never returns null
- getBlock
  
  @CheckReturnValue @CheckForNull public Block getBlock(@Nonnull String name)
  
  Get an existing Block. First looks up assuming that name is a User Name. If this fails looks up assuming that name is a System Name. If both fail, returns null.
  
  Parameters:
  
  name - the name of an existing block
  
  Returns:
  
  a Block or null if none found
- getByDisplayName
  
  @CheckReturnValue @CheckForNull public Block getByDisplayName(@Nonnull String key)
- setDefaultSpeed
  
  public void setDefaultSpeed(@Nonnull String speed)
  
  Parameters:
  
  speed - the speed
  
  Throws:
  
  IllegalArgumentException - if provided speed is invalid
- getDefaultSpeed
  
  @CheckReturnValue @Nonnull public String getDefaultSpeed()
- getBeanTypeHandled
  
  @CheckReturnValue @Nonnull public String getBeanTypeHandled(boolean plural)
  
  Description copied from interface: Manager
  
  Get the user-readable name of the type of NamedBean handled by this manager.
  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<Block>
  
  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
- getBlocksOccupiedByRosterEntry
  
  @CheckReturnValue @Nonnull public List<Block> getBlocksOccupiedByRosterEntry(@Nonnull BasicRosterEntry re)
  
  Get a list of blocks which the supplied roster entry appears to be occupying. A block is assumed to contain this roster entry if its value is the RosterEntry itself, or a string with the entry's id or dcc address.
  
  Parameters:
  
  re - the roster entry
  
  Returns:
  
  list of block system names
- propertyChange
  
  public void propertyChange(PropertyChangeEvent e)
  
  Listen for changes to the power state from any power managers in use in order to track how long it's been since power was applied to the layout. This information is used in Block.goingActive() when deciding whether to restore a block's last value. Also listen for additions/removals or PowerManagers
  
  Specified by:
  
  propertyChange in interface PropertyChangeListener
  
  Overrides:
  
  propertyChange in class AbstractManager<Block>
  
  Parameters:
  
  e - the change event
- timeSinceLastLayoutPowerOn
  
  public long timeSinceLastLayoutPowerOn()
  
  Get the amount of time since the layout was last powered up, in milliseconds. If the layout has not been powered up as far as JMRI knows it returns a very long time indeed.
  
  Returns:
  
  long int
- provide
  
  @Nonnull public Block provide(@Nonnull String name)
  
  Description copied from interface: ProvidingManager
  
  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<Block>
  
  Parameters:
  
  name - User name, system name, or address which can be promoted to system name
  
  Returns:
  
  Never null
