      • HelperInjector

        public HelperInjector​(java.lang.String requestingName,
                      java.util.List<java.lang.String> helperClassNames,
                      java.util.List<java.lang.String> helperResourceNames)
        Construct HelperInjector.
        Parameters:
        helperClassNames - binary names of the helper classes to inject. These class names must be resolvable by the classloader returned by io.opentelemetry.javaagent.tooling.Utils#getAgentClassLoader(). Classes are injected in the order provided. This is important if there is interdependency between helper classes that requires them to be injected in a specific order.
