@Enhance protected static class ClassLoadingStrategy.Default.InjectionDispatcher extends Object implements ClassLoadingStrategy.Configurable<ClassLoader>
A class loading strategy which applies a class loader injection while applying a given
ProtectionDomain
on class injection.Important: Class injection requires access to JVM internal methods that are sealed by security managers and the Java Platform module system. Since Java 11, access to these methods is no longer feasible unless those packages are explicitly opened.

Method Detail

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 interfaceClassLoadingStrategy<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.
-
with
public ClassLoadingStrategy.Configurable<ClassLoader> with(ProtectionDomain protectionDomain)
Overrides the implicitly set defaultProtectionDomain
with an explicit one.- Specified by:
with
in interfaceClassLoadingStrategy.Configurable<ClassLoader>
- Parameters:
protectionDomain
- The protection domain to apply ornull
if no protection domain is set.- Returns:
- This class loading strategy with an explicitly set
ProtectionDomain
.
-
with
public ClassLoadingStrategy.Configurable<ClassLoader> with(PackageDefinitionStrategy packageDefinitionStrategy)
Defines the supplied package definition strategy to be used for defining packages.- Specified by:
with
in interfaceClassLoadingStrategy.Configurable<ClassLoader>
- Parameters:
packageDefinitionStrategy
- The package definer to be used.- Returns:
- A version of this class loading strategy that applies the supplied package definition strategy.
-
allowExistingTypes
public ClassLoadingStrategy.Configurable<ClassLoader> allowExistingTypes()
Determines if this class loading strategy should not throw an exception when attempting to load a class that was already loaded. In this case, the already loaded class is used instead of the generated class.- Specified by:
allowExistingTypes
in interfaceClassLoadingStrategy.Configurable<ClassLoader>
- Returns:
- A version of this class loading strategy that does not throw an exception when a class is already loaded.
-
opened
public ClassLoadingStrategy.Configurable<ClassLoader> opened()
With an opened class loading strategy, it is assured that types can be added to the class loader, either by indirect injection using this strategy or by creating a class loader that explicitly supports injection.- Specified by:
opened
in interfaceClassLoadingStrategy.Configurable<ClassLoader>
- Returns:
- A version of this class loading strategy that opens for future injections into a class loader.
