## Class PartitionListenerAdapter

- java.lang.Object
- - org.apache.geode.cache.partition.PartitionListenerAdapter

- All Implemented Interfaces:
    PartitionListener

      public class PartitionListenerAdapter
      extends java.lang.Object
      implements PartitionListener

  Utility class that implements all methods in `PartitionListener` with empty implementations. Applications can subclass this class and only override the methods of interest.

  Subclasses declared in a Cache XML file, it must also implement `Declarable`

  Note : Please request help on the Geode developer mailing list (dev@geode.apache.org) before using these APIs.

    - #### afterPrimary

          public void afterPrimary(int bucketId)

      Description copied from interface: `PartitionListener`
      Callback invoked when any bucket in a partitioned region becomes primary
      Specified by:
        `afterPrimary` in interface `PartitionListener`
      Parameters:
        `bucketId` - id of the bucket which became primary

    - #### afterRegionCreate

          public void afterRegionCreate(Region<?,?> region)

      Description copied from interface: `PartitionListener`
      Callback invoked when a partition region is created
      Specified by:
        `afterRegionCreate` in interface `PartitionListener`
      Parameters:
        `region` - handle of the region which is created

    - #### afterBucketRemoved

          public void afterBucketRemoved(int bucketId,
                                         java.lang.Iterable<?> keys)

      Description copied from interface: `PartitionListener`
      Callback invoked after a bucket has been removed from a member (e.g. during rebalancing). This API is useful for maintaining external data structures by bucket id or key.
      Specified by:
        `afterBucketRemoved` in interface `PartitionListener`
      Parameters:
        `bucketId` - id of the bucket removed
        `keys` - keys in the bucket removed

    - #### afterBucketCreated

          public void afterBucketCreated(int bucketId,
                                         java.lang.Iterable<?> keys)

      Description copied from interface: `PartitionListener`
      Callback invoked after a bucket has been created in a member (e.g. during rebalancing). This API is useful for maintaining external data structures by bucket id or key. Note that this API is invoked after the initial image has been completed so creates and destroys may occur in the keys. It is best to use this API during periods of no cache activity.
      Specified by:
        `afterBucketCreated` in interface `PartitionListener`
      Parameters:
        `bucketId` - id of the bucket created
        `keys` - keys in the bucket created
