Member Function Documentation

◆ Close() [1/2]

template<class TKey , class TResult >
void Apache::Geode::Client::ICqListener< TKey, TResult >::Close ( )
inherited

Called when the region containing this callback is destroyed, when the cache is closed.

Implementations should clean up 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.

Cache.Close, Region.DestroyRegion

◆ Close() [2/2]

template<class TKey , class TResult >
void Apache::Geode::Client::ICqListener< TKey, TResult >::Close ( )
inherited

Called when the region containing this callback is destroyed, when the cache is closed.

Implementations should clean up 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.

◆ OnCqConnected()

template<class TKey , class TResult >
virtual void Apache::Geode::Client::ICqStatusListener< TKey, TResult >::OnCqConnected ( )
virtual

Called when the cq establishes a connection with a server

◆ OnCqDisconnected()

template<class TKey , class TResult >
virtual void Apache::Geode::Client::ICqStatusListener< TKey, TResult >::OnCqDisconnected ( )
virtual

Called when the cq loses connection with all servers.

◆ OnError() [1/2]

template<class TKey , class TResult >
void Apache::Geode::Client::ICqListener< TKey, TResult >::OnError ( CqEvent< TKey, TResult >^  ev)
inherited

Handles the event of an entry's value being modified in a region.

This entry previously existed in this region in the local cache, but its previous value may have been null.

Parameters
evEntryEvent denotes the event object associated with updating the entry.
See also
Region.Put

◆ OnError() [2/2]

template<class TKey , class TResult >
void Apache::Geode::Client::ICqListener< TKey, TResult >::OnError ( CqEvent ev)
inherited

Handles the event of an entry's value being modified in a region.

This entry previously existed in this region in the local cache, but its previous value may have been null.

Parameters
evEntryEvent denotes the event object associated with updating the entry.

Region.Put

◆ OnEvent() [1/2]

template<class TKey , class TResult >
void Apache::Geode::Client::ICqListener< TKey, TResult >::OnEvent ( CqEvent< TKey, TResult >^  ev)
inherited

Handles the event of a new key being added to a region.

The entry did not previously exist in this region in the local cache (even with a null value).

This function does not throw any exception.

Parameters
evDenotes the event object associated with the entry creation.

Region.Create, Region.Put, Region.Get

◆ OnEvent() [2/2]

template<class TKey , class TResult >
void Apache::Geode::Client::ICqListener< TKey, TResult >::OnEvent ( CqEvent ev)
inherited

Handles the event of a new key being added to a region.

The entry did not previously exist in this region in the local cache (even with a null value).

This function does not throw any exception.

Parameters
evDenotes the event object associated with the entry creation.
