Field Detail

### ANNOTATOR

    public static final ChangeType ANNOTATOR

Method Detail

### hasListeners

    protected boolean hasListeners()

### getChangeSupport

    protected ChangeSupport getChangeSupport(ChangeType ct)

### addChangeListener

    public final void addChangeListener(ChangeListener cl)

  Description copied from interface: `Changeable`
  Add a listener that will be informed of all changes.

  Specified by:
    `addChangeListener` in interface `Changeable`
  Parameters:
    `cl` - the ChangeListener to add

### addChangeListener

    public final void addChangeListener(ChangeListener cl,
                                        ChangeType ct)

  Description copied from interface: `Changeable`
  Add a listener that will be informed of changes of a given type.

  Specified by:
    `addChangeListener` in interface `Changeable`
  Parameters:
    `cl` - the ChangeListener
    `ct` - the ChangeType it is to be informed of

### removeChangeListener

    public final void removeChangeListener(ChangeListener cl)

  Description copied from interface: `Changeable`
  Remove a listener that was interested in all types of changes.

  Specified by:
    `removeChangeListener` in interface `Changeable`
  Parameters:
    `cl` - a ChangeListener to remove

### removeChangeListener

    public final void removeChangeListener(ChangeListener cl,
                                           ChangeType ct)

  Description copied from interface: `Changeable`
  Remove a listener that was interested in a specific types of changes.

  Specified by:
    `removeChangeListener` in interface `Changeable`
  Parameters:
    `cl` - a ChangeListener to remove
    `ct` - the ChangeType that it was interested in

### isUnchanging

    public final boolean isUnchanging(ChangeType ct)

  Description copied from interface: `Changeable`

  A particular ChangeType can never be raised by this Changeable.

  If this returns true, then it is guaranteed that change events of this type (and all child types) can never under any circumstances be fired by this Changeable instance. If it returns false, that does not mean that this type of event will or even can be raised, but that it is worth registering listeners incase.

  Specified by:
    `isUnchanging` in interface `Changeable`
  Parameters:
    `ct` - the ChangeType to check
  Returns:
    true if ChangeEvents of this type are guaranteed to never be fired

### getAnnotaters

    public Set getAnnotaters()

### getDB

    public SequenceDB getDB()
                     throws BioException

  Throws:
    `BioException`

### getDistDataSource

    public DistDataSource getDistDataSource()
                                     throws BioException

  Overrides:
    `getDistDataSource` in class `DataSource`
  Throws:
    `BioException`
