Class ClassInfo

  • public class ClassInfo
extends java.lang.Object
    The class info struct serves for saving class information. A class info may hold a class itself or the class name for resolving the class. This struct should be used at all places where classes are meant to be send to remote nodes. In this case the class info will only transfer the class name forcing the receiver to lookup the class itself. The class loader for resolving a class info can be found by using the corresponding resource identifier (rid) of the component or service that uses the class.

      • EMPYT_CLASSINFO_ARRAY

        public static final ClassInfo[] EMPYT_CLASSINFO_ARRAY
        Empty class info array.

      • typename

        protected java.lang.String typename
        The service interface type as string.

      • type

        protected java.lang.Class<?> type
        The service interface type.

      • geninfo

        protected java.lang.String geninfo
        The generic type info (e.g. when obtained via method parameter).

      • classloader

        protected java.lang.ClassLoader classloader
        The classloader with which this info was loaded. Note 1: This must not be the same as method.getClass().getClassLoader() because the latter returns the loader responsible for the class which could be higher in the parent hierarchy. Note 2: The check current_cl==last_cl is not perfect because when invoked with a parent classloader it will reload the class (although not necessary)
