Class ClassLoadingStrategy.UsingLookup

java.lang.Object

net.bytebuddy.dynamic.loading.ClassLoadingStrategy.UsingLookup

All Implemented Interfaces:

ClassLoadingStrategy<ClassLoader>

Enclosing interface:

ClassLoadingStrategy<T extends ClassLoader>

@HashCodeAndEqualsPlugin.Enhance
public static class ClassLoadingStrategy.UsingLookup
extends Object
implements ClassLoadingStrategy<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.

Constructor Detail

UsingLookup

protected UsingLookup(ClassInjector classInjector)

Creates a new class loading strategy that uses a lookup type.

Parameters:

classInjector - The class injector to use.

Method Detail

of

public static ClassLoadingStrategy<ClassLoader> of(Object lookup)

Creates a new class loading strategy that uses a java.lang.invoke.MethodHandles$Lookup instance.

Parameters:

lookup - The lookup instance to use for defining new types.

Returns:

A suitable class loading strategy.

load

public Map<TypeDescription,Class<?>> load(ClassLoader classLoader,
                                          Map<TypeDescription,byte[]> types)

Loads a given collection of classes given their binary representation.

Specified by:

load in interface ClassLoadingStrategy<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.
