ObserverMethod

Type Parameters:

T - the event type

All Superinterfaces:

Prioritized
```
public interface ObserverMethod<T>
extends Prioritized
```
Represents an observer method of an enabled bean. Defines everything the container needs to know about an observer method.

If a custom implementation of this interface does not override either notify(Object) or notify(EventContext), the container automatically detects the problem and treats it as a definition error.

Modifier and Type	Method and Description
`java.lang.Class<?>`	`getBeanClass()` Obtains the class of the type that declares the observer method.
`java.util.Set<java.lang.annotation.Annotation>`	`getObservedQualifiers()` Obtains the set of observed event qualifiers.
`java.lang.reflect.Type`	`getObservedType()` Obtains the observed event type.
`default int`	`getPriority()` The priority that will be used by the container to determine the notification order in which event observer methods are invoked.
`Reception`	`getReception()` Obtains the specified `Reception` for the observer method.
`TransactionPhase`	`getTransactionPhase()` Obtains the specified `TransactionPhase` for the observer method.
`default boolean`	`isAsync()` Determines if this observer method is asynchronous
`default void`	`notify(EventContext<T> eventContext)` Calls the observer method, passing the given event context.
`default void`	`notify(T event)` Calls the observer method, passing the given event object.

  - getBeanClass
```
java.lang.Class<?> getBeanClass()
```
    Obtains the class of the type that declares the observer method.
    
    Returns:
    
    the defining class
  - getObservedType
```
java.lang.reflect.Type getObservedType()
```
    Obtains the observed event type.
    
    Returns:
    
    the observed event type
  - getObservedQualifiers
```
java.util.Set<java.lang.annotation.Annotation> getObservedQualifiers()
```
    Obtains the set of observed event qualifiers.
    
    Returns:
    
    the observed event qualifiers
  - getReception
```
Reception getReception()
```
    Obtains the specified Reception for the observer method. This indicates if the observer is conditional or not.
    
    Returns:
    
    the Reception
  - getTransactionPhase
```
TransactionPhase getTransactionPhase()
```
    Obtains the specified TransactionPhase for the observer method.
    
    Returns:
    
    the TransactionPhase
  - getPriority
```
default int getPriority()
```
    The priority that will be used by the container to determine the notification order in which event observer methods are invoked.
    
    Specified by:
    
    getPriority in interface Prioritized
    
    Returns:
    
    The priority that will be used by the container to determine the notification order in which event observer methods are invoked.
    
    Since:
    
    2.0
  - notify
```
default void notify(T event)
```
    Calls the observer method, passing the given event object.
    
    The implementation of this method for a custom observer method is responsible for deciding whether to call the method if the getReception() returns Reception.IF_EXISTS.
    
    Parameters:
    
    event - the event object
  - notify
```
default void notify(EventContext<T> eventContext)
```
    Calls the observer method, passing the given event context.
    The container should always call this method, but the default implementation delegates to notify(Object).
    The implementation of this method for a custom observer method is responsible for deciding whether to call the method if the getReception() returns Reception.IF_EXISTS.
    
    Parameters:
    
    eventContext - EventContext used to notify observers
  - isAsync
```
default boolean isAsync()
```
    Determines if this observer method is asynchronous
    
    Returns:
    
    returns true if the method is an asynchronous observer method (i.e. defined with ObservesAsync), otherwise returns false
