Method Details

getState

public InjectableContext.ContextState getState()

Specified by:

getState in interface InjectableContext

Returns:

the current state

activate

public InjectableContext.ContextState activate(InjectableContext.ContextState initialState)

Description copied from interface: ManagedContext

Activate the context.

If invoked with null parameter, a fresh InjectableContext.ContextState is automatically created.

Specified by:

activate in interface ManagedContext

Parameters:

initialState - The initial state, may be null

Returns:

the context state

deactivate

public void deactivate()

Description copied from interface: ManagedContext

Deactivate the context - do not destroy existing contextual instances.

Specified by:

deactivate in interface ManagedContext

getIfActive

public <T> T getIfActive(jakarta.enterprise.context.spi.Contextual<T> contextual,
 Function<jakarta.enterprise.context.spi.Contextual<T>,jakarta.enterprise.context.spi.CreationalContext<T>> creationalContextFun)

Description copied from interface: InjectableContext

If the context is active then return an existing instance of certain contextual type or create a new instance, otherwise return a null value. This allows for the Context.isActive() check and the actual creation to happen in a single method, which gives a performance benefit by performing fewer thread local operations.

Specified by:

getIfActive in interface InjectableContext

Type Parameters:

T - the type of contextual type

Parameters:

contextual - the contextual type

creationalContextFun - the creational context function

Returns:

the contextual instance, or a null value

get

public <T> T get(jakarta.enterprise.context.spi.Contextual<T> contextual,
 jakarta.enterprise.context.spi.CreationalContext<T> creationalContext)

Specified by:

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

get

public <T> T get(jakarta.enterprise.context.spi.Contextual<T> contextual)

Specified by:

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

isActive

public boolean isActive()

Specified by:

isActive in interface jakarta.enterprise.context.spi.Context

destroy

public void destroy()

Description copied from interface: InjectableContext

Destroys the current context and all existing contextual instances.

Specified by:

destroy in interface InjectableContext

destroy

public void destroy(jakarta.enterprise.context.spi.Contextual<?> contextual)

Specified by:

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

destroy

public void destroy(InjectableContext.ContextState state)

Description copied from interface: InjectableContext

Destroy all contextual instances from the given state.

The default implementation is not optimized and does not guarantee proper sychronization. Implementations of this interface are encouraged to provide an optimized implementation of this method.

Specified by:

destroy in interface InjectableContext

Parameters:

state -

initializeState

public CurrentManagedContext.CurrentContextState initializeState()

Description copied from interface: ManagedContext

Creates a new InjectableContext.ContextState.

Creating a context state does not fire @Initialized event for given context.

Specified by:

initializeState in interface ManagedContext

Returns:

a new initialized context state

traceLog

protected org.jboss.logging.Logger traceLog()

traceActivate

protected void traceActivate(InjectableContext.ContextState initialState)

traceDeactivate

protected void traceDeactivate()

traceDestroy

protected void traceDestroy(InjectableContext.ContextState state)

notActive

protected abstract jakarta.enterprise.context.ContextNotActiveException notActive()
