org.bedework.synch.shared.cnctrs.AbstractConnector<T,TI,TN,Tconf,InfoT>

Type Parameters:

T - Connector subclass

TI - Connector instance subclass

TN - Notification subclass

Tconf - Configuration class

All Implemented Interfaces:

Connector<TI,TN,Tconf>, org.bedework.util.logging.Logged

public abstract class AbstractConnector<T,TI extends AbstractConnectorInstance<?,?,?>,TN extends Notification<?>,Tconf extends ConnectorConfigI,InfoT extends BaseSubscriptionInfo>
extends Object
implements org.bedework.util.logging.Logged, Connector<TI,TN,Tconf>

Method Details

getConnectorId

public String getConnectorId()

Returns:

the connector id

start

public void start(String connectorId,
 Tconf conf,
 String callbackUri,
 SynchEngine syncher)

Description copied from interface: Connector

Start the connector. A response of null means no synch available.

The callback url is unique to the connector. It will be used as a path prefix to allow the callback service to locate the handler for incoming callback requests.

For example, if the callback context is /synchcb/ and the connector id is "bedework" then the callback uri might be /synchcb/bedework/. The connector might append a uid to that path to allow it to locate the active subscription for which the callback is intended.

Specified by:

start in interface Connector<T,TI extends AbstractConnectorInstance<?,?,?>,TN extends Notification<?>>

Parameters:

connectorId - - registered id for the connector

getStatus

public String getStatus()

Specified by:

getStatus in interface Connector<T,TI extends AbstractConnectorInstance<?,?,?>,TN extends Notification<?>>

Returns:

a useful status message

isStarted

public boolean isStarted()

Specified by:

isStarted in interface Connector<T,TI extends AbstractConnectorInstance<?,?,?>,TN extends Notification<?>>

Returns:

true if we started

isFailed

public boolean isFailed()

Specified by:

isFailed in interface Connector<T,TI extends AbstractConnectorInstance<?,?,?>,TN extends Notification<?>>

Returns:

true if we failed in some way

isStopped

public boolean isStopped()

Specified by:

isStopped in interface Connector<T,TI extends AbstractConnectorInstance<?,?,?>,TN extends Notification<?>>

Returns:

true if we're stopped

isManager

public boolean isManager()

Specified by:

isManager in interface Connector<T,TI extends AbstractConnectorInstance<?,?,?>,TN extends Notification<?>>

Returns:

true if we are the manager

isReadOnly

public boolean isReadOnly()

Description copied from interface: Connector

Is this a read-only connector?

Specified by:

isReadOnly in interface Connector<T,TI extends AbstractConnectorInstance<?,?,?>,TN extends Notification<?>>

Returns:

boolean

getTrustLastmod

public boolean getTrustLastmod()

Description copied from interface: Connector

Specified by:

getTrustLastmod in interface Connector<T,TI extends AbstractConnectorInstance<?,?,?>,TN extends Notification<?>>

Returns:

boolean

getId

public String getId()

Specified by:

getId in interface Connector<T,TI extends AbstractConnectorInstance<?,?,?>,TN extends Notification<?>>

Returns:

id provided at start

getCallbackUri in interface Connector<T,TI extends AbstractConnectorInstance<?,?,?>,TN extends Notification<?>>

Returns:

callbackUri provided at start

getSyncher

public SynchEngine getSyncher()

Specified by:

getSyncher in interface Connector<T,TI extends AbstractConnectorInstance<?,?,?>,TN extends Notification<?>>

Returns:

syncher provided at start

getIcalObjectFactory

public ietf.params.xml.ns.icalendar_2.ObjectFactory getIcalObjectFactory()

Specified by:

getIcalObjectFactory in interface Connector<T,TI extends AbstractConnectorInstance<?,?,?>,TN extends Notification<?>>

Returns:

an object factory for icalendar

getPropertyInfo

public PropertiesInfo getPropertyInfo()

Description copied from interface: Connector

Information about properties required for subscriptions via this connector.

Specified by:

getPropertyInfo in interface Connector<T,TI extends AbstractConnectorInstance<?,?,?>,TN extends Notification<?>>

Returns:

list of info

getSkipList

public List<Object> getSkipList()

Specified by:

getSkipList in interface Connector<T,TI extends AbstractConnectorInstance<?,?,?>,TN extends Notification<?>>

Returns:

list of icalendar properties to skip.

stop

public void stop()
          throws SynchException

Description copied from interface: Connector

Shut down the connector

Specified by:

stop in interface Connector<T,TI extends AbstractConnectorInstance<?,?,?>,TN extends Notification<?>>

Throws:

SynchException

makeInstance

public abstract TI makeInstance(Subscription sub,
 org.bedework.synch.wsmessages.SynchEndType end)
                         throws SynchException

Throws:

SynchException

getConnectorInstance

public TI getConnectorInstance(Subscription sub,
 org.bedework.synch.wsmessages.SynchEndType end)
                        throws SynchException

Description copied from interface: Connector

Called to obtain a connector instance for a subscription. A response of null means no synch available.

Specified by:

getConnectorInstance in interface Connector<T,TI extends AbstractConnectorInstance<?,?,?>,TN extends Notification<?>>

Parameters:

sub - - the subscription

end - - which end

Returns:

null for no synch else a connector instance.

Throws:

Description copied from interface: Connector

Will create a notification batch object which will be passed to a synchling for processing. When processing is complete respond will be called.

The resource URI has been stripped of the context element and the element which identifies the connector. What remains is used by the connector to determine a subscription id allowing retrieval of the subscription from the synch engine.

Specified by:

handleCallback in interface Connector<T,TI extends AbstractConnectorInstance<?,?,?>,TN extends Notification<?>>

Returns:

Notification with 1 or more Notification items or null for no action.
