    public StoreBase()

Method Detail

### getInfo

    public java.lang.String getInfo()

  Return the info for this Store.

  Specified by:
    `getInfo` in interface `Store`

### getStoreName

    public java.lang.String getStoreName()

  Return the name for this Store, used for logging.

### setManager

    public void setManager(Manager manager)

    `addLifecycleListener` in interface `Lifecycle`
  Parameters:
    `listener` - The listener to add

### findLifecycleListeners

    public LifecycleListener[] findLifecycleListeners()

  Get the lifecycle listeners associated with this lifecycle. If this Lifecycle has no listeners registered, a zero-length array is returned.

  Specified by:
    `findLifecycleListeners` in interface `Lifecycle`

### removeLifecycleListener

    public void removeLifecycleListener(LifecycleListener listener)

  Remove a lifecycle event listener from this component.

  Specified by:
    `removeLifecycleListener` in interface `Lifecycle`
  Parameters:
    `listener` - The listener to add

### addPropertyChangeListener

    public void addPropertyChangeListener(java.beans.PropertyChangeListener listener)

  Add a property change listener to this component.

  Specified by:

### start

    public void start()
               throws LifecycleException

  Prepare for the beginning of active use of the public methods of this component. This method should be called after `configure()`, and before any of the public methods of the component are utilized.

  Specified by:
    `start` in interface `Lifecycle`
  Throws:
    `LifecycleException` - if this component detects a fatal error that prevents this component from being used

### stop
