CDI (Jakarta EE Platform API)

java.lang.Object
- jakarta.enterprise.inject.spi.CDI<T>

Type Parameters:

All Implemented Interfaces:

Instance<T>, Provider<T>, Iterable<T>
```
public abstract class CDI<T>
extends Object
implements Instance<T>
```

    provider - the provider to use
    
    Throws:

    Returns:
    
    the BeanManager
  - getBeanContainer
```
