Class AbstractCDI<T>

java.lang.Object

javax.enterprise.inject.spi.CDI<T>

org.jboss.weld.AbstractCDI<T>

Type Parameters:

T -

All Implemented Interfaces:

Iterable<T>, javax.enterprise.inject.Instance<T>, javax.inject.Provider<T>, org.jboss.weld.inject.WeldInstance<T>

Direct Known Subclasses:

SimpleCDI, WeldContainer

public abstract class AbstractCDI<T>
extends javax.enterprise.inject.spi.CDI<T>
implements org.jboss.weld.inject.WeldInstance<T>

Abstract implementation of CDI which forwards all Instance methods to a delegate. Furthermore, it allows the calling class to be identified using the getCallingClassName() method.
