firebase::remote_config::ConfigUpdateListenerRegistration

#include <config_update_listener_registration.h>

Calling Remove stops the listener from receiving config updates and unregisters itself.

Summary

If remove is called and no other listener registrations remain, the connection to the Remote Config backend is closed. Subsequently calling AddOnConfigUpdate will re-open the connection.

Public functions

ConfigUpdateListenerRegistration

 ConfigUpdateListenerRegistration()

Creates an invalid ConfigUpdateListenerRegistration that has to be reassigned before it can be used.

Calling Remove() on an invalid ConfigUpdateListenerRegistration is a no-op.

ConfigUpdateListenerRegistration

 ConfigUpdateListenerRegistration(
  const ConfigUpdateListenerRegistration & other
)

Copy constructor.

ConfigUpdateListenerRegistration can be efficiently copied because it simply refers to the same underlying listener. If there is more than one copy of a ConfigUpdateListenerRegistration, after calling Remove on one of them, the listener is removed, and calling Remove on any other copies will be a no-op.

Parameters
other

ConfigUpdateListenerRegistration

 ConfigUpdateListenerRegistration(
  ConfigUpdateListenerRegistration && other
)

Move constructor.

Moving is more efficient than copying for a ConfigUpdateListenerRegistration. After being moved from, a ConfigUpdateListenerRegistration is equivalent to its default-constructed state.

Details
Parameters
other

Remove

void Remove()

Remove the listener being tracked by this ConfigUpdateListenerRegistration.

After the initial call, subsequent calls to Remove have no effect.

operator=

ConfigUpdateListenerRegistration & operator=(
  const ConfigUpdateListenerRegistration & other
)

Copy assignment operator.

ConfigUpdateListenerRegistration can be efficiently copied because it simply refers to the same underlying listener. If there is more than one copy of a ConfigUpdateListenerRegistration, after calling Remove on one of them, the listener is removed, and calling Remove on any other copies will be a no-op.

Parameters
other
Returns
Reference to the destination ConfigUpdateListenerRegistration.

operator=

ConfigUpdateListenerRegistration & operator=(
  ConfigUpdateListenerRegistration && other
)

Move assignment operator.

Moving is more efficient than copying for a ConfigUpdateListenerRegistration. After being moved from, a ConfigUpdateListenerRegistration is equivalent to its default-constructed state.

Parameters
other
Returns
Reference to the destination ConfigUpdateListenerRegistration.
