Package com.vaadin.quarkus.context

Class AbstractContext

java.lang.Object

com.vaadin.quarkus.context.AbstractContext

All Implemented Interfaces:

io.quarkus.arc.InjectableContext, javax.enterprise.context.spi.AlterableContext, javax.enterprise.context.spi.Context

Direct Known Subclasses:

RouteScopedContext, UIScopedContext, VaadinServiceScopedContext, VaadinSessionScopedContext

public abstract class AbstractContext
extends Object
implements io.quarkus.arc.InjectableContext

A modified copy of org.apache.deltaspike.core.util.context.AbstractContext. A skeleton containing the most important parts of a custom CDI Context. An implementing Context needs to implement the missing methods from the AlterableContext interface and getContextualStorage(Contextual, boolean).

Method Detail

getContextualStorage

protected abstract ContextualStorage getContextualStorage(javax.enterprise.context.spi.Contextual<?> contextual,
                                                          boolean createIfNotExist)

An implementation has to return the underlying storage which contains the items held in the Context.

Parameters:

contextual - the contextual type

createIfNotExist - whether a ContextualStorage shall get created if it doesn't yet exist.

Returns:

the underlying storage

getActiveContextualStorages

protected List<ContextualStorage> getActiveContextualStorages()

Gets all active contextual storages.

Returns:

a list of contextual storages.

get

public <T> T get(javax.enterprise.context.spi.Contextual<T> bean)

Specified by:

get in interface javax.enterprise.context.spi.Context

get

public <T> T get(javax.enterprise.context.spi.Contextual<T> bean,
                 javax.enterprise.context.spi.CreationalContext<T> creationalContext)

Specified by:

get in interface javax.enterprise.context.spi.Context

destroy

public void destroy(javax.enterprise.context.spi.Contextual<?> bean)

Destroy the Contextual Instance of the given Bean.

Specified by:

destroy in interface javax.enterprise.context.spi.AlterableContext

Parameters:

bean - dictates which bean shall get cleaned up

destroyAllActive

public void destroyAllActive()

destroys all the Contextual Instances in the Storage returned by getContextualStorage(Contextual, boolean).

destroyAllActive

public static Map<Object,ContextualInstanceInfo<?>> destroyAllActive(ContextualStorage storage)

Destroys all the Contextual Instances in the specified ContextualStorage. This is a static method to allow various holder objects to cleanup properly in @PreDestroy.

Parameters:

storage - a contextual storage

Returns:

a storage map of destroyed objects

destroy

public void destroy()

Specified by:

destroy in interface io.quarkus.arc.InjectableContext

getState

public io.quarkus.arc.InjectableContext.ContextState getState()

Specified by:

getState in interface io.quarkus.arc.InjectableContext

checkActive

protected void checkActive()

Make sure that the Context is really active.

Throws:

javax.enterprise.context.ContextNotActiveException - if there is no active Context for the current Thread.

destroyBean

public static void destroyBean(javax.enterprise.context.spi.Contextual bean,
                               ContextualInstanceInfo<?> contextualInstanceInfo)
