EE4J 10.0.0 · jakarta.enterprise.inject.build.compatible.spi.SyntheticBeanCreator

Creation function for a synthetic bean defined by SyntheticBeanBuilder. CDI container will create an instance of the creation function every time when it needs to obtain an instance of the synthetic bean. Implementations must be public classes with a public zero-parameter constructor; they must not be beans.

Method Summary

Modifier and Type	Method and Description
public T	Returns: an instance of the bean, may only be `null` if the synthetic bean is `@Dependent` create(Instance<Object> an `Instance` that can be used to lookup other beans, never `null` lookup, Parameters the parameter map, never `null` params) Creates an instance of the synthetic bean.

public T create(Instance<Object> lookup, Parameters params) Creates an instance of the synthetic bean. May only return `null` if the synthetic bean is `@Dependent`. The `Instance` parameter may be used to simulate producer method parameter injection. However, `@Dependent` bean instances obtained from the `Instance` during execution remain managed until the synthetic bean instance is destroyed. Therefore, implementations are encouraged to destroy unneeded `@Dependent` bean instances obtained from the `Instance`. If the synthetic bean is `@Dependent`, the `InjectionPoint` to which it is injected may be looked up from the `Instance` parameter. The parameter map contains the same values that were passed to the `SyntheticBeanBuilder` that defined the synthetic bean. Parameters lookup:Instance<Object> an `Instance` that can be used to lookup other beans, never `null` params:Parameters the parameter map, never `null` Returns:T an instance of the bean, may only be `null` if the synthetic bean is `@Dependent`

public T create(Instance<Object> lookup, Parameters params)

Creates an instance of the synthetic bean. May only return null if the synthetic bean is @Dependent.

The Instance parameter may be used to simulate producer method parameter injection. However, @Dependent bean instances obtained from the Instance during execution remain managed until the synthetic bean instance is destroyed. Therefore, implementations are encouraged to destroy unneeded @Dependent bean instances obtained from the Instance.

If the synthetic bean is @Dependent, the InjectionPoint to which it is injected may be looked up from the Instance parameter.

The parameter map contains the same values that were passed to the SyntheticBeanBuilder that defined the synthetic bean.

Parameters

lookup:Instance<Object>: an Instance that can be used to lookup other beans, never null
params:Parameters: the parameter map, never null

Returns:T

an instance of the bean, may only be null if the synthetic bean is @Dependent

public Interface SyntheticBeanCreator<T>
