Class WeldInvocationContextImpl

java.lang.Object

org.jboss.weld.util.ForwardingInvocationContext

org.jboss.weld.interceptor.proxy.WeldInvocationContextImpl

All Implemented Interfaces:

javax.interceptor.InvocationContext, org.jboss.weld.interceptor.WeldInvocationContext

public class WeldInvocationContextImpl
extends ForwardingInvocationContext
implements org.jboss.weld.interceptor.WeldInvocationContext

Weld's InvocationContext implementation. This is a forwarding implementation that delegates most method calls to an underlying InvocationContext. This allows multiple interceptor chains to be combined. A call to proceed() invokes the chain of intercepors in the given order. Once the chain finishes, the proceed() method of the delegate is invoked which results in the target method being invoked in case of SimpleInvocationContext. Otherwise, the delegate chain is run.
