public void start()

Description copied from interface: SCANode

Start the composite loaded in the node.

Specified by:

start in interface SCANode

stop

public void stop()

Description copied from interface: SCANode

Stop the composite loaded in the node.

Specified by:

stop in interface SCANode

cast

public <B,R extends org.osoa.sca.CallableReference<B>> R cast(B target)
                                                 throws java.lang.IllegalArgumentException

Description copied from interface: SCAClient

Cast a type-safe reference to a CallahbleReference. Converts a type-safe reference to an equivalent CallableReference; if the target refers to a service then a ServiceReference will be returned, if the target refers to a callback then a CallableReference will be returned.

Specified by:

cast in interface SCAClient

Type Parameters:

B - the Java type of the business interface for the reference

R - the type of reference to be returned

Parameters:

target - a reference proxy provided by the SCA runtime

Returns:

a CallableReference equivalent for the proxy

Throws:

java.lang.IllegalArgumentException - if the supplied instance is not a reference supplied by the SCA runtime

getService

public <B> B getService(java.lang.Class<B> businessInterface,
                        java.lang.String serviceName)

Description copied from interface: SCAClient

Returns a proxy for a service provided by a component in the SCA domain.

Specified by:

getService in interface SCAClient

Type Parameters:

B - the Java type of the business interface for the service

Parameters:

businessInterface - the interface that will be used to invoke the service

serviceName - the name of the service

Returns:

an object that implements the business interface

getServiceReference

public <B> org.osoa.sca.ServiceReference<B> getServiceReference(java.lang.Class<B> businessInterface,
                                                                java.lang.String name)

Description copied from interface: SCAClient

Returns a ServiceReference for a service provided by a component in the SCA domain.

Specified by:

getServiceReference in interface SCAClient

Type Parameters:

B - the Java type of the business interface for the service

Parameters:

businessInterface - the interface that will be used to invoke the service

name - the name of the service

Returns:

a ServiceReference for the designated service

getExtensionPointRegistry

Returns the extension point registry used by this node.

Returns:

getComposite

public Composite getComposite()

Returns the composite being run by this node.

Returns:

getCompositeActivator

public CompositeActivator getCompositeActivator()
