Description copied from interface: IRemoteServiceContainerAdapter

Returns an array of IRemoteServiceReference objects. The returned array of IRemoteServiceReference objects contains services that were registered under the specified class and match the specified idFilter, and filter criteria.

The list is valid at the time of the call to this method, however since the Framework is a very dynamic environment, services can be modified or unregistered at anytime.

target is a remote container to connect to.

filter is used to select the registered service whose properties objects contain keys and values which satisfy the filter. See Filter for a description of the filter string syntax.

If filter is null, all registered services are considered to match the filter. If filter cannot be parsed, an InvalidSyntaxException will be thrown with a human readable message where the filter became unparsable.

Specified by:

getRemoteServiceReferences in interface IRemoteServiceContainerAdapter

Parameters:

targetID - an target to connect to if enclosing container is not already connected. May be null.

Description copied from interface: IRemoteServiceContainerAdapter

Returns an array of IRemoteServiceReference objects. The returned array of IRemoteServiceReference objects contains services that were registered under the specified class and match the specified idFilter, and filter criteria.

Note this method assumes that the enclosing container has previously been connected, and uses the idFilter to filter among targets within the previously connected set of container IDs. To request connection as part of reference lookup, see IRemoteServiceContainerAdapter.getRemoteServiceReferences(ID, String, String).

The list is valid at the time of the call to this method, however since the Framework is a very dynamic environment, services can be modified or unregistered at anytime.

idFilter is used to select a registered services that were registered by a given set of containers with id in idFilter. Only services exposed by a container with id in idFilter will be returned.

If idFilter is null, all containers are considered to match the filter.

filter is used to select the registered service whose properties objects contain keys and values which satisfy the filter. See Filter for a description of the filter string syntax.

If filter is null, all registered services are considered to match the filter. If filter cannot be parsed, an InvalidSyntaxException will be thrown with a human readable message where the filter became unparsable.

Specified by:

getRemoteServiceReferences in interface IRemoteServiceContainerAdapter

Parameters:

idFilter - an array of ID instances that will restrict the search for matching container ids If null, all remote containers will be considered in search for matching IRemoteServiceReference instances. May be null.

clazz - the fully qualified name of the interface class that describes the desired service. Must not be null.

filter - The filter criteria. May be null.

Returns:

Array of IRemoteServiceReferences matching given search criteria or null if no services are found that match the search.

Throws:

Specified by:

registerRemoteService in interface IRemoteServiceContainerAdapter

Parameters:

clazzes - the interface classes that the service exposes to remote clients. Must not be null and must not be an empty array.

service - the service object. Under normal conditions this object must

• not be null
• implement all of the classes specified by the first parameter

The only situation when the service object may be null is if the service property Constants.SERVICE_REGISTER_PROXY is set in the properties. If Constants.SERVICE_REGISTER_PROXY is set in the properties parameter (to an arbitrary value), then the service object may then be null.

properties - to be associated with service

Returns:

IRemoteServiceRegistration the service registration. Will not return null .

ungetRemoteService

public boolean ungetRemoteService(IRemoteServiceReference ref)

Description copied from interface: IRemoteServiceContainerAdapter

Unget IRemoteServiceReference. Release all resources associated with the given IRemoteServiceReference. This method should be called by users of the IRemoteServiceReference that have previously called IRemoteServiceContainerAdapter.getRemoteService(IRemoteServiceReference). If this method returns true, then the previously used IRemoteService will no longer be usable.

Specified by:

ungetRemoteService in interface IRemoteServiceContainerAdapter

Parameters:

ref - the IRemoteServiceReference to unget

Returns:

true if unget successful, false if not. If this method returns true, then the IRemoteService instance previously retrieved via the given IRemoteServiceReference instance provided will no longer be usable.

Overrides:

handleSharedObjectMsg in class BaseSharedObject

Parameters:

msg - the SharedObjectMsg received

Returns:

true if the msg has been completely handled and subsequent processing should stop. False if processing should continue

Description copied from interface: IRemoteServiceContainerAdapter

Asynchronously returns an array of IRemoteServiceReference objects. The returned array of IRemoteServiceReference objects contains services that were registered under the specified class and match the specified idFilter, and filter criteria.

Note this method assumes that the enclosing container has previously been connected, and uses the idFilter to filter among targets within the previously connected set of container IDs. To request connection as part of reference lookup, see IRemoteServiceContainerAdapter.getRemoteServiceReferences(ID, String, String).

The IFuture is returned immediately, and subsequent calls to IFuture.get() or IFuture.get(long) will return the actual results received. The type of the Object returned from IFuture.get() will be IRemoteServiceReference [].

The list is valid at the time of the call to this method, however since the Framework is a very dynamic environment, services can be modified or unregistered at anytime.

idFilter is used to select a registered services that were registered by a given set of containers with id in idFilter. Only services exposed by a container with id in idFilter will be returned.

If idFilter is null, all containers are considered to match the filter.

filter is used to select the registered service whose properties objects contain keys and values which satisfy the filter. See Filter for a description of the filter string syntax.

Specified by:

asyncGetRemoteServiceReferences in interface IRemoteServiceContainerAdapter

Parameters:

idFilter - an array of ID instances that will restrict the search for matching container ids If null, all remote containers will be considered in search for matching IRemoteServiceReference instances. May be null.

clazz - the fully qualified name of the interface class that describes the desired service. Must not be null.

filter - The filter criteria. May be null.

Returns:

IFuture that through subsequent calls to IFuture#get() will return IRemoteServiceReference [] with IRemoteServiceReferences matching given search criteria. Will not return null.

Since:

3.0

public IRemoteFilter createRemoteFilter(java.lang.String filter)
                                 throws org.osgi.framework.InvalidSyntaxException

Description copied from interface: IRemoteServiceContainerAdapter

Creates a IRemoteFilter object. This IRemoteFilter object may be used to match a IRemoteServiceReference object or a Dictionary object.

If the filter cannot be parsed, an InvalidSyntaxException will be thrown with a human readable message where the filter became unparsable.

Specified by:

createRemoteFilter in interface IRemoteServiceContainerAdapter

Parameters:

filter - The filter string.

Returns:

A IRemoteFilter object encapsulating the filter string.

Throws:

org.osgi.framework.InvalidSyntaxException - If filter contains an invalid filter string that cannot be parsed.

getRemoteServiceReference

public IRemoteServiceReference getRemoteServiceReference(IRemoteServiceID serviceId)

Description copied from interface: IRemoteServiceContainerAdapter

Get the remote service reference known to this container for the given IRemoteServiceID. Note that this method must be guaranteed not to block by the provider implementation.

Specified by:

getRemoteServiceReference in interface IRemoteServiceContainerAdapter

Parameters:

serviceId - the serviceID to retrieve the IRemoteServiceReference for.

Returns:

IRemoteServiceReference the remote service reference associated with the given serviceID. Will return null if no IRemoteServiceReference found for the given serviceID.

getRemoteServiceID

public IRemoteServiceID getRemoteServiceID(ID containerId,
                                           long containerRelativeId)

Description copied from interface: IRemoteServiceContainerAdapter

Get a remote service ID from a containerID and a containerRelative long value. Will return a non-null value if the IRemoteServiceRegistration/Reference is currently 'known' to this container adapter. null if not.

Specified by:

getRemoteServiceID in interface IRemoteServiceContainerAdapter

Parameters:

containerId - the containerID that is the server/host for the remote service. Must not be null. This must be the containerID for the server/host of the remote service.

containerRelativeId - the long value identifying the remote service relative to the container ID.

Returns:

IRemoteServiceID instance if the associated IRemoteServiceRegistration/Reference is known to this container adapter, null if it is not.

setConnectContextForAuthentication

public void setConnectContextForAuthentication(IConnectContext connectContext)

Description copied from interface: IRemoteServiceContainerAdapter

Set connect context for authentication upon subsequent calls to IRemoteServiceContainerAdapter.getRemoteServiceReferences(ID[], String, String) or IRemoteServiceContainerAdapter.asyncGetRemoteServiceReferences(ID[], String, String). This method should be called with a non-null connectContext in order to allow authentication to occur during.

Specified by:
