matchesNamespaceOnType

static EventHandlerSelector matchesNamespaceOnType(String namespace)

Implementation of the EventHandlerSelector that matches EventHandlerDescriptors for which the given namespace matches with the value of the Namespace annotation.

The Namespace is searched for on several levels in the following order:

1. On the EventProcessorDefinition.EventHandlerDescriptor.beanType()
2. The enclosing classes (from innermost to outermost) of the EventProcessorDefinition.EventHandlerDescriptor.beanType()
3. The package of the EventProcessorDefinition.EventHandlerDescriptor.beanType()
4. The module of the EventProcessorDefinition.EventHandlerDescriptor.beanType()

Parameters:

namespace - the namespace to match with the value of the Namespace annotation

Returns:

an EventHandlerSelector that matches the given namespace with the value of the Namespace annotation
