Class AbstractEnhancedAnnotated<T,S>

java.lang.Object

org.jboss.weld.annotated.enhanced.jlr.AbstractEnhancedAnnotated<T,S>

Type Parameters:

T -

S -

All Implemented Interfaces:

Annotated, EnhancedAnnotated<T,S>

Direct Known Subclasses:

AbstractEnhancedAnnotatedMember, EnhancedAnnotatedParameterImpl, EnhancedAnnotatedTypeImpl

public abstract class AbstractEnhancedAnnotated<T,S>
extends Object
implements EnhancedAnnotated<T,S>

Represents functionality common for all annotated items, mainly different mappings of the annotations and meta-annotations

AbstractAnnotatedItem is an immutable class and therefore threadsafe
