Class MethodInvocationStrategy

java.lang.Object

org.jboss.weld.injection.MethodInvocationStrategy

public abstract class MethodInvocationStrategy
extends Object

Encapsulates various strategies for invoking a method injection point. The default implementation supports all the possible scenarios including dependency injection to parameters. In addition, there are optimized implementations for commonly used scenarios such as:

• an observer method with event parameter only
• an observer method with event parameter and a BeanManager injection point (common in extensions)
• an observer method with event parameter and an EventMetadata injection point
