## Interface IElementChangeEvent

- All Known Implementing Classes:
    ElementChangeEvent

      public interface IElementChangeEvent

  Describes a change to the structure or contents of one or more trees of elements of a Handly-based model. The changes to the elements are described by the associated delta objects carried by this event.

- - ### Field Summary

    Fields
    Modifier and Type | Field and Description
    --- | ---
    `static int` | `POST_CHANGE` Event type constant (bit-mask) indicating a notification that occurs during the corresponding POST_CHANGE resource change notification.
    `static int` | `POST_RECONCILE` Event type constant (bit-mask) indicating a notification that occurs as a result of a working copy reconcile operation.

  - ### Method Summary

    All Methods Instance Methods Abstract Methods
    Modifier and Type | Method and Description
    --- | ---
    `IElementDelta[]` | `getDeltas()` Returns the top-level deltas describing the change.
    `int` | `getType()` Returns the type of event being reported.

- - ### Field Detail

    - #### POST_CHANGE

          static final int POST_CHANGE

      Event type constant (bit-mask) indicating a notification that occurs during the corresponding POST_CHANGE resource change notification.
      See Also:
        Constant Field Values

    - #### POST_RECONCILE

          static final int POST_RECONCILE

      Event type constant (bit-mask) indicating a notification that occurs as a result of a working copy reconcile operation.
      See Also:
        Constant Field Values

  - ### Method Detail

    - #### getType

          int getType()

      Returns the type of event being reported.

      Some event types make sense for most models and are predefined in this interface, while others are model-specific and are defined by the model implementor. The range for model-specific types starts from `0x10000` and includes the upper 16 bits of `int` value. The lower 16 bits are reserved for predefined generic event types.

      Returns:
        the type of event being reported
      See Also:
        `POST_CHANGE`, `POST_RECONCILE`

    - #### getDeltas

          IElementDelta[] getDeltas()

      Returns the top-level deltas describing the change. Each top-level delta describes a change in a separate element tree.
      Returns:
        the top-level deltas describing the change (never `null`, never empty). Clients must not modify the returned array.
