Class DynaCastResolver

java.lang.Object
  org.iqual.chaplin.DynaCastResolver

public class DynaCastResolver
extends Object

This class is associated with all dynacast handlers during the code injection phase. It decides whether the given type can be handled by the associated dynacast handler. This class is built upon CastsTo annotation which can be attached to the dynacast handler's class. This annotation contains a list of types to which the handler casts any incoming value. If the class does not have that annotation it is supposed to be potentially able to convert to all type.

The FieldRedirector uses the list of instances of this class during the code injection phase when it captures CHECKCAST instruction and wants to filter out those handlers which do not cast to the type associated with the CHECKCAST instruction. Then it creates an array which consists of class names of all those handlers which are potentially able to cast to the type. This array is then statically passed to DynaCastManager which dynamically resolves in the runtime which dynacast handler will convert the value.
