Extension of CqListener.
Adds two new methods to CqListener, one that is called when the cq is connected and one that is called when the cq is disconnected
- Since
- 7.0
| virtual void apache::geode::client::CqListener::close |
( |
| ) |
|
|
virtualinherited |
Called when the region containing this callback is closed or destroyed, when the cache is closed, or when a callback is removed from a region using an AttributesMutator.
Implementations should cleanup any external resources such as database connections. Any runtime exceptions this method throws will be logged.
It is possible for this method to be called multiple times on a single callback instance, so implementations must be tolerant of this.

This method is invoked when there is an error during CQ processing.
The error can appear while applying query condition on the event. e.g if the event doesn't has attributes as specified in the CQ query. This event does contain an error. The newValue may or may not be available, and will be NULLPTR if not available.
| virtual void apache::geode::client::CqListener::onEvent |
( |
const CqEvent & |
aCqEvent | ) |
|
|
virtualinherited |
This method is invoked when an event is occurred on the region that satisfied the query condition of this CQ.
This event does not contain an error.

Atomically decrement reference count, the SharedBase object is automatically deleted when its reference count goes to zero.
