ConfigurationListener

enum ConfigurationEventType

Values:

enumerator CM_UPDATED

The ConfigurationEvent type for when a Configuration object has been updated.

enumerator CM_DELETED

The ConfigurationEvent type for when a Configuration object has been removed.

class cppmicroservices::service::cm::ConfigurationEvent
#include <cppmicroservices/cm/ConfigurationListener.hpp>

The ConfigurationEvent object is passed to the ConfigurationListener when the configuration object for any service is updated or removed by ConfigurationAdmin.

Public Functions

inline ConfigurationEvent(ServiceReference<ConfigurationAdmin> configAdmin, const ConfigurationEventType type, std::string factoryPid, std::string pid)
inline ServiceReference<ConfigurationAdmin> const &getReference() const noexcept

Get the ServiceReference object of the Configuration Admin Service that created this event.

Return

the service reference of this ConfigurationEvent

inline std::string const &getPid() const noexcept

Get the PID of this ConfigurationEvent.

Return

the PID of this ConfigurationEvent

inline std::string const &getFactoryPid() const noexcept

Get the Factory PID which is responsible for this Configuration.

Return

the FactoryPID of this ConfigurationEvent

inline ConfigurationEventType getType() const noexcept

Get the type of this Configuration.

Return

the ConfigurationEventType of this ConfigurationEvent

class cppmicroservices::service::cm::ConfigurationListener
#include <cppmicroservices/cm/ConfigurationListener.hpp>

The ConfigurationListener interface is the interface that Declarative Services implements to receive updates from the ConfigurationAdmin implementation for all configuration object updates.

ConfigurationAdmin sends updates for all configuration object updates. It is up to DS to determine if this is a configuration object associated with a service being managed by DS.

Public Functions

virtual void configurationEvent(ConfigurationEvent const &event) = 0

Called whenever the Configuration for any service is updated or removed from ConfigurationAdmin.

Remark

This class is threadsafe

Parameters

virtual ~ConfigurationListener() noexcept = default
