Class ClassLoadingStrategy.UsingLookup

  • All Implemented Interfaces:
    ClassLoadingStrategy<java.lang.ClassLoader>
    Enclosing interface:
    ClassLoadingStrategy<T extends java.lang.ClassLoader>
    public static class ClassLoadingStrategy.UsingLookup
extends java.lang.Object
implements ClassLoadingStrategy<java.lang.ClassLoader>
    A class loading strategy that uses a java.lang.invoke.MethodHandles$Lookup instance for defining types. A lookup instance can define types only in the same class loader and in the same package as the type within which it was created. The supplied lookup must have package privileges, i.e. it must not be a public lookup.

                                                                    java.util.Map<TypeDescription,​byte[]> types)
        Description copied from interface: ClassLoadingStrategy
        Loads a given collection of classes given their binary representation.
        Specified by:
        load in interface ClassLoadingStrategy<java.lang.ClassLoader>
        Parameters:
        classLoader - The class loader to used for loading the classes.
        types - Byte array representations of the types to be loaded mapped by their descriptions, where an iteration order defines an order in which they are supposed to be loaded, if relevant.
        Returns:
        A collection of the loaded classes which will be initialized in the iteration order of the returned collection.
