Method Detail

initialize

void initialize(BaseAdaptor adaptor)

Gets called by the adaptor during FrameworkAdaptor.initialize(EventPublisher). This method allows an adaptor hook to save the adaptor object for later.

Parameters:

adaptor - the adaptor object associated with this AdaptorHook.

frameworkStart

void frameworkStart(BundleContext context)
                    throws BundleException

Gets called by the adaptor during FrameworkAdaptor.frameworkStart(BundleContext). This method allows an adaptor hook to execute code when the framework is starting (e.g. to register services).

Parameters:

context - the system bundle context

Throws:

BundleException - if an error occurs

frameworkStop

void frameworkStop(BundleContext context)
                   throws BundleException

Gets called by the adaptor during FrameworkAdaptor.frameworkStop(BundleContext). This method allows an adaptor hook to execute code when the framework is stopped (e.g. to unregister services).

Parameters:

context - the system bundle context

Throws:

BundleException - if an error occurs.

frameworkStopping

void frameworkStopping(BundleContext context)

Gets called by the adaptor during FrameworkAdaptor.frameworkStopping(BundleContext). This method allows an adaptor hook to execute code when the framework is about to start the shutdown process.

Parameters:

context - the system bundle context

addProperties

void addProperties(Properties properties)

Gets called by the adaptor during FrameworkAdaptor.getProperties(). This method allows an adaptor hook to add property values to the adaptor properties object.

Parameters:

properties - the adaptor properties object.

mapLocationToURLConnection

URLConnection mapLocationToURLConnection(String location)
                                         throws IOException

Gets called by the adaptor during FrameworkAdaptor.mapLocationToURLConnection(String). The adaptor will call this method for each configured adaptor hook until one adaptor hook returns a non-null value. If no adaptor hook returns a non-null value then the adaptor will perform the default behavior.

Parameters:

location - a bundle location string to be converted to a URLConnection

Returns:

the URLConnection converted from the bundle location or null.

Throws:

IOException - if an error occured creating the URLConnection

handleRuntimeError

void handleRuntimeError(Throwable error)

Gets called by the adaptor during FrameworkAdaptor.handleRuntimeError(Throwable). The adaptor will call this method for each configured adaptor hook.

Parameters:

error - the unexpected error that occured.

createFrameworkLog

FrameworkLog createFrameworkLog()

Gets called by the adaptor during FrameworkAdaptor.getFrameworkLog(). The adaptor will call this method for each configured adaptor hook until one adaptor hook returns a non-null value. If no adaptor hook returns a non-null value then the adaptor will return null.

Returns:

a FrameworkLog object or null.
