Member Function Documentation

boolean alma::acs::component::dynwrapper::DynamicProxyFactory::checkMethodMatching	(	Class	facade,
		ComponentInvocationHandler	invHandler
	)			throws DynWrapperException `[inline, private]`

Checks if all methods in facade can be mapped to a corresponding method in delegate using the various mappers for argument translation.

TODO: make this check optional (property etc.) since it's not needed for stable and already verified interfaces. Perhaps move from runtime to buildtime?

Parameters:

	facade	the interface that is presented to the client (serverside: the container; clientside: the client application).
	invHandler	the invocation handler that can delegate the facade method calls (serverside: to the component implementation; clientside: to the CORBA stub).

Returns:: true if all parameters can be mapped automatically both ways. false if at least one pair of parameters requires manual mapping.

Exceptions:

DynWrapperException if delegate does not provide a peer method for at least one method in facade. Currently two methods are considered peers if they have the same name and the same number of parameters.

public<T> T alma::acs::component::dynwrapper::DynamicProxyFactory::createClientProxy	(	Class< T >	componentInterface,
		org.omg.CORBA.Object	corbaStub,
		Class<?>	corbaOperationsIF
	)			throws DynWrapperException `[inline, package]`

Creates a proxy object for a corba stub for a component. The proxy object will delegate calls to the corba stub, and will translate parameters as necessary.

Parameters:

	componentInterface	the component interface
	corbaStub

Returns:: Object

Exceptions:

DynWrapperException

Object alma::acs::component::dynwrapper::DynamicProxyFactory::createServerProxy	(	Class<?extends ACSComponentOperations >	corbaIF,
		ComponentLifecycle	componentImpl,
		Class<?>	componentIF
	)			throws DynWrapperException `[inline]`

Creates a proxy object for a component implementation. The proxy object will delegate calls to the component, and will translate parameters as necessary.

Parameters:

	corbaIF	the IDL-generated xxOperations interface.
	componentImpl	the component implementation class that implements `componentIF`. This may be identical with `corbaIF`, or could be some other similar interface, e.g. one that uses XML binding classes.
	componentIF	the interface of the component to which calls will be delegated.

Returns:: the proxy object that implements corbaIF and delegates to componentImpl.

Exceptions:

DynWrapperException

static DynamicProxyFactory alma::acs::component::dynwrapper::DynamicProxyFactory::getDynamicProxyFactory ( Logger logger ) [inline, static]

Singleton accessor. The logger must be provided because this class is used both inside the container as well as outside in tests and applications that are clients to container/components. The latter cases might not want to use central ACS logging.

Parameters:

logger
