Constructor Detail

LDIFConnectionHandler

public LDIFConnectionHandler()

Creates a new instance of this connection handler. All initialization should be performed in the initializeConnectionHandler method.

Method Detail

initializeConnectionHandler

public void initializeConnectionHandler(ServerContext serverContext,
                                        org.forgerock.opendj.server.config.server.LDIFConnectionHandlerCfg configuration)

Description copied from class: ConnectionHandler

Initializes this connection handler provider based on the information in the provided connection handler configuration.

Specified by:

initializeConnectionHandler in class ConnectionHandler<org.forgerock.opendj.server.config.server.LDIFConnectionHandlerCfg>

Parameters:

serverContext - The server context.

configuration - The connection handler configuration that contains the information to use to initialize this connection handler.

finalizeConnectionHandler

public void finalizeConnectionHandler(org.forgerock.i18n.LocalizableMessage finalizeReason)

Description copied from class: ConnectionHandler

Closes this connection handler so that it will no longer accept new client connections. Implementations should disconnect any existing connections.

Specified by:

finalizeConnectionHandler in class ConnectionHandler<org.forgerock.opendj.server.config.server.LDIFConnectionHandlerCfg>

Parameters:

finalizeReason - The reason that this connection handler should be finalized.

getConnectionHandlerName

public String getConnectionHandlerName()

Description copied from class: ConnectionHandler

Retrieves a name that may be used to refer to this connection handler. Every connection handler instance (even handlers of the same type) must have a unique name.

Specified by:

getConnectionHandlerName in class ConnectionHandler<org.forgerock.opendj.server.config.server.LDIFConnectionHandlerCfg>

Returns:

A unique name that may be used to refer to this connection handler.

getProtocol

public String getProtocol()

Description copied from class: ConnectionHandler

Retrieves the name of the protocol used to communicate with clients. It should take into account any special naming that may be needed to express any security mechanisms or other constraints in place (e.g., "LDAPS" for LDAP over SSL).

Specified by:

getProtocol in class ConnectionHandler<org.forgerock.opendj.server.config.server.LDIFConnectionHandlerCfg>

Returns:

The name of the protocol used to communicate with clients.

getListeners

public Collection<HostPort> getListeners()

Description copied from class: ConnectionHandler

Retrieves information about the listener(s) that will be used to accept client connections.

Specified by:

getListeners in class ConnectionHandler<org.forgerock.opendj.server.config.server.LDIFConnectionHandlerCfg>

Returns:

Information about the listener(s) that will be used to accept client connections, or an empty list if this connection handler does not accept connections from network clients.

getClientConnections

public Collection<ClientConnection> getClientConnections()

Description copied from class: ConnectionHandler

Retrieves the set of active client connections that have been established through this connection handler.

Specified by:

getClientConnections in class ConnectionHandler<org.forgerock.opendj.server.config.server.LDIFConnectionHandlerCfg>

Returns:

The set of active client connections that have been established through this connection handler.

run

public void run()

Description copied from class: ConnectionHandler

Operates in a loop, accepting new connections and ensuring that requests on those connections are handled properly.

Specified by:

run in interface Runnable

Specified by:

run in class ConnectionHandler<org.forgerock.opendj.server.config.server.LDIFConnectionHandlerCfg>

toString

public void toString(StringBuilder buffer)

Description copied from class: ConnectionHandler

Appends a string representation of this connection handler to the provided buffer.

Specified by:

toString in class ConnectionHandler<org.forgerock.opendj.server.config.server.LDIFConnectionHandlerCfg>

Parameters:

buffer - The buffer to which the information should be appended.

isConfigurationAcceptable

public boolean isConfigurationAcceptable(org.forgerock.opendj.server.config.server.ConnectionHandlerCfg configuration,
                                         List<org.forgerock.i18n.LocalizableMessage> unacceptableReasons)

Description copied from class: ConnectionHandler

Indicates whether the provided configuration is acceptable for this connection handler. It should be possible to call this method on an uninitialized connection handler instance in order to determine whether the connection handler would be able to use the provided configuration.

Note that implementations which use a subclass of the provided configuration class will likely need to cast the configuration to the appropriate subclass type.

Overrides:

isConfigurationAcceptable in class ConnectionHandler<org.forgerock.opendj.server.config.server.LDIFConnectionHandlerCfg>

Parameters:

configuration - The connection handler configuration for which to make the determination.

unacceptableReasons - A list that may be used to hold the reasons that the provided configuration is not acceptable.

Returns:

true if the provided configuration is acceptable for this connection handler, or false if not.

isConfigurationChangeAcceptable

public boolean isConfigurationChangeAcceptable(org.forgerock.opendj.server.config.server.LDIFConnectionHandlerCfg configuration,
                                               List<org.forgerock.i18n.LocalizableMessage> unacceptableReasons)

Specified by:

isConfigurationChangeAcceptable in interface org.forgerock.opendj.config.server.ConfigurationChangeListener<org.forgerock.opendj.server.config.server.LDIFConnectionHandlerCfg>

applyConfigurationChange

public org.forgerock.opendj.config.server.ConfigChangeResult applyConfigurationChange(org.forgerock.opendj.server.config.server.LDIFConnectionHandlerCfg configuration)

Specified by:

applyConfigurationChange in interface org.forgerock.opendj.config.server.ConfigurationChangeListener<org.forgerock.opendj.server.config.server.LDIFConnectionHandlerCfg>

getComponentEntryDN

public org.forgerock.opendj.ldap.DN getComponentEntryDN()

Description copied from class: ConnectionHandler

Retrieves the DN of the configuration entry with which this alert generator is associated.

Specified by:

getComponentEntryDN in interface AlertGenerator

Specified by:

getComponentEntryDN in class ConnectionHandler<org.forgerock.opendj.server.config.server.LDIFConnectionHandlerCfg>

Returns:

The DN of the configuration entry with which this alert generator is associated.

getClassName

public String getClassName()

Description copied from interface: AlertGenerator

Retrieves the fully-qualified name of the Java class for this alert generator implementation.

Specified by:

Returns:

The fully-qualified name of the Java class for this alert generator implementation.

getAlerts

public LinkedHashMap<String,String> getAlerts()

Description copied from interface: AlertGenerator

Retrieves information about the set of alerts that this generator may produce. The map returned should be between the notification type for a particular notification and the human-readable description for that notification. This alert generator must not generate any alerts with types that are not contained in this list.

Specified by:

getAlerts in interface AlertGenerator

Returns:

Information about the set of alerts that this generator may produce.
