MultiBinaryLongMap.BinaryLongMapListener (Oracle® Coherence Java API Reference)

All Superinterfaces:

EventListener

All Known Implementing Classes:

JournalBinaryStore.ClearListener, MultiBinaryLongMap.PrimaryBinaryLongMap

Enclosing class:

MultiBinaryLongMap
```
public static interface MultiBinaryLongMap.BinaryLongMapListener
extends EventListener
```
A listener that allows the owner of one of the delegating maps to respond to changes in the key set made by an owner of another delegating map.
Events may be raised to the BinaryLongMapListener while holding resource locks on the primary BinaryLongMap, so the listener is not permitted to further modify the contents of the primary BinaryLongMap synchronously.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`void`	`keyAdded(Binary binKey)`	A notification that the primary map has added a new Binary/long key/value mapping; this implicitly creates a new key/value mapping in each delegating map, with the value being `0L`.
`void`	`keyRemoving(Binary binKey)`	A notification that the primary map is removing a Binary/long key/value mapping; this implies that the existing key/value mapping for the same Binary key in each delegating map is also being removed.
`void`	`mapCleared()`	A notification that the primary map has been cleared; this implies that all of the existing key/value mappings in each delegating map have also been removed.
`void`	`mapClearing()`	A notification that the primary map is about to be cleared; this implies that all of the existing key/value mappings in each delegating map are about to be removed, but that no per-mapping events will be generated in response to those removals.

- Method Detail
  - keyAdded
```
void keyAdded(Binary binKey)
```
    A notification that the primary map has added a new Binary/long key/value mapping; this implicitly creates a new key/value mapping in each delegating map, with the value being 0L.
    
    Parameters:
    
    binKey - the key that was added
  - keyRemoving
```
void keyRemoving(Binary binKey)
```
    A notification that the primary map is removing a Binary/long key/value mapping; this implies that the existing key/value mapping for the same Binary key in each delegating map is also being removed.
    
    Parameters:
    
    binKey - the key that is being removed
  - mapClearing
```
void mapClearing()
```
    A notification that the primary map is about to be cleared; this implies that all of the existing key/value mappings in each delegating map are about to be removed, but that no per-mapping events will be generated in response to those removals.
  - mapCleared
```
void mapCleared()
```
    A notification that the primary map has been cleared; this implies that all of the existing key/value mappings in each delegating map have also been removed.
