A parameter injection annotation that can be used on component entry points and transformer methods defined using the @Transformer annotation, this annotation controls how the current message payload is passed into a method by performing automatic transformation of the message payload to match the annotated parameter type. For example, if you are expecting an XML document, this can be injected into a component entry point and automatically converted into a org.wc3.dom.Document.
public class MyComponent {
public Object process(@Payload Document doc) {
// do stuff
}
}
