Interface InvocationManager

All Known Implementing Classes:

InvocationManagerImpl

@Contract
public interface InvocationManager

InvocationManager provides interface to keep track of component context on a per-thread basis

Method Summary

Modifier and Type	Method	Description
List<? extends ComponentInvocation>	getAllInvocations()
<T extends ComponentInvocation> T	getCurrentInvocation()	Returns the current Invocation object associated with the current thread
<T extends ComponentInvocation> T	getPreviousInvocation()	Returns the previous Invocation object associated with the current thread.
boolean	isInvocationStackEmpty()	return true iff no invocations on the stack for this thread
ApplicationEnvironment	peekAppEnvironment()	Gets the current application environment on the current thread
void	popAppEnvironment()	To be called by the infrastructure to indicate that some user code not associated with any Java EE specification is finished being called.
<T extends ComponentInvocation> void	postInvoke(T inv)	To be called by a Container to indicate that the Container has just completed the invocation of a method on a component.
<T extends ComponentInvocation> void	preInvoke(T inv)	To be called by a Container to indicate that the Container is about to invoke a method on a component.
void	pushAppEnvironment(ApplicationEnvironment env)	To be called by the infrastructure to indicate that some user code not associated with any Java EE specification may be called.

Method Detail

preInvoke

<T extends ComponentInvocation> void preInvoke(T inv)
                                        throws InvocationException

To be called by a Container to indicate that the Container is about to invoke a method on a component. The preInvoke and postInvoke must be called in pairs and well-nested.

Parameters:

inv - the Invocation object

Throws:

InvocationException

postInvoke

<T extends ComponentInvocation> void postInvoke(T inv)
                                         throws InvocationException

To be called by a Container to indicate that the Container has just completed the invocation of a method on a component. The preInvoke and postInvoke must be called in pairs and well-nested.

Parameters:

inv - the Invocation object

Throws:

InvocationException

getCurrentInvocation

<T extends ComponentInvocation> T getCurrentInvocation()

Returns the current Invocation object associated with the current thread

getPreviousInvocation

<T extends ComponentInvocation> T getPreviousInvocation()
                                                 throws InvocationException

Returns the previous Invocation object associated with the current thread. Returns null if there is none. This is typically used when a component A calls another component B within the same VM. In this case, it might be necessary to obtain information related to both component A using getPreviousInvocation() and B using getCurrentInvocation()

Throws:

InvocationException

isInvocationStackEmpty

boolean isInvocationStackEmpty()

return true iff no invocations on the stack for this thread

getAllInvocations

List<? extends ComponentInvocation> getAllInvocations()

registerComponentInvocationHandler

void registerComponentInvocationHandler(ComponentInvocation.ComponentInvocationType type,
                                        RegisteredComponentInvocationHandler handler)

pushAppEnvironment

void pushAppEnvironment(ApplicationEnvironment env)

To be called by the infrastructure to indicate that some user code not associated with any Java EE specification may be called. In particular must be called by the Weld integration layer to indicate the application environment in which the portable extensions are running

The pushAppEnvironment and popAppEnvironment must be called in pairs and well-nested.

Parameters:

env - may not be null. Information about the application environment

peekAppEnvironment

ApplicationEnvironment peekAppEnvironment()

Gets the current application environment on the current thread

Returns:

The current ApplicationEnvironment, or null if there is none

popAppEnvironment

void popAppEnvironment()

To be called by the infrastructure to indicate that some user code not associated with any Java EE specification is finished being called. In particular must be called by the Weld integration layer to indicate the application environment in which the portable extensions are running

The pushAppEnvironment and popAppEnvironment must be called in pairs and well-nested.

Parameters:

env - may not be null. Information about the application environment
