Method Detail

createApplication

AriesApplication createApplication(IDirectory source)
                                   throws ManagementException

Create an AriesApplication from a local resource. The application won't be automatically resolved if the archive does not contain a deployment manifest.

Parameters:

source - .eba file, or exploded directory

Returns:

AriesApplication

Throws:

ManagementException

createApplication

AriesApplication createApplication(URL url)
                                   throws ManagementException

Create an AriesApplication from a remote resource. The application won't be automatically resolved if the archive does not contain a deployment manifest.

Parameters:

url -

Returns:

the application.

Throws:

ManagementException

install

AriesApplicationContext install(AriesApplication app)
                                throws BundleException,
                                       ManagementException,
                                       ResolverException

Install an AriesApplication - i.e. load its bundles into the runtime, but do not start them. If the application is not resolved, a call to resolve(AriesApplication, ResolveConstraint...) will be performed and the resolved application will be installed. In such a case the resolved application can be obtained by calling AriesApplicationContext.getApplication() on the returned ApplicationContext.

Parameters:

app - Application to install

Returns:

AriesApplicationContext, a handle to an application in the runtime

Throws:

BundleException

ManagementException

ResolverException

uninstall

void uninstall(AriesApplicationContext app)
               throws BundleException

Uninstall an AriesApplication - i.e. unload its bundles from the runtime.

Parameters:

app - The installed application to uninstall

Throws:

BundleException

addApplicationListener

void addApplicationListener(AriesApplicationListener l)

Add an AriesApplicationListener

Parameters:

l -

removeApplicationListener

void removeApplicationListener(AriesApplicationListener l)

Remove an AriesApplicationListener

Parameters:

l -

update

AriesApplicationContext update(AriesApplication app,
                               DeploymentMetadata depMf)
                               throws UpdateException

Update an application's deployment and apply the changes to the runtime if the application is deployed

Parameters:

app - The application to change

depMf - The new deployment metadata

Returns:

AriesApplicationContext Returns a new application context if the app is currently deployed, or null if the app is not currently installed

Throws:

UpdateException - if the deployment changes could not be effected in the runtime

IllegalArgumentException - if the deployment metadata does not correspond to the same application (same symbolic name and same version)

resolve

AriesApplication resolve(AriesApplication originalApp,
                         ResolveConstraint... constraints)
                         throws ResolverException

Resolve an AriesApplication against a set of constraints. Each ResolveConstraint represents a single proposed change to the content of an application. If no constraints are given, a default resolution will be performed.

Parameters:

originalApp - Original application

constraints - Constraints

Returns:

New AriesApplication

Throws:

ResolverException
