Interface ObserverInfo

  • public interface ObserverInfo
    Observers are:
    • observer methods
    • synthetic observers
    Observer methods directly correspond to a method declaration in program source code. Synthetic observers don't and are instead defined through other mechanisms, such as extensions.
    Since:
    4.0

    • Method Detail

      • eventType

        Type eventType()
        Returns the observed event type of this observer.
        Returns:
        the observed event type of this observer, never null

      • qualifiers

        Collection<AnnotationInfo> qualifiers()
        Returns a collection of observed event qualifiers, represented as AnnotationInfo.
        Returns:
        immutable collection of observed event qualifiers, never null

      • declaringClass

        ClassInfo declaringClass()
        Returns the class that declares this observer. In case of synthetic observers, returns the class that was designated as a declaring class during synthetic observer registration.
        Returns:
        the class that declares this observer, never null

      • observerMethod

        MethodInfo observerMethod()
        Returns the declaration of this observer method. Returns null if this is a synthetic observer.
        Returns:
        this observer method, or null if this is a synthetic observer

      • eventParameter

        ParameterInfo eventParameter()
        Returns the event parameter of this observer method. Returns null if this is a synthetic observer.
        Returns:
        the event parameter of this observer method, or null if this is a synthetic observer

      • bean

        BeanInfo bean()
        Returns the bean that declares this observer method. Returns null if this is a synthetic observer.
        Returns:
        the bean declaring this observer method, or null if this is a synthetic observer

      • isSynthetic

        boolean isSynthetic()
        Returns whether this observer is synthetic.
        Returns:
        whether this observer is synthetic

      • priority

        int priority()
        Returns the priority of this observer. This is typically defined by adding the @Priority annotation to the event parameter of the observer method. If the annotation is not used, the default priority, as defined by the CDI specification, is returned,
        Returns:
        the priority of this observer

      • isAsync

        boolean isAsync()
        Returns whether this observer is asynchronous. For observer methods, this means whether this observer method uses @ObservesAsync.
        Returns:
        whether this observer is asynchronous

      • reception

        Reception reception()
        Returns the reception type of this observer. Allows distinguishing conditional observer methods from always notified observer methods. Returns Reception.ALWAYS if this is a synthetic observer.
        Returns:
        the reception type of this observer, never null

      • transactionPhase

        TransactionPhase transactionPhase()
        Returns the transaction phase of this transactional observer. Returns TransactionPhase.IN_PROGRESS if this is a regular synchronous observer. Returns null if this is an asynchronous observer.
        Returns:
        the transaction phase of this observer, or null if this is an asynchronous observer
