Constructor	Description
UsingReflection(ClassLoader classLoader)	Creates a new injector for the given ClassLoader and a default ProtectionDomain and a trivial PackageDefinitionStrategy which does not trigger an error when discovering existent classes.
UsingReflection(ClassLoader classLoader, ProtectionDomain protectionDomain)	Creates a new injector for the given ClassLoader and a default PackageDefinitionStrategy where the injection of existent classes does not trigger an error.
UsingReflection(ClassLoader classLoader, ProtectionDomain protectionDomain, PackageDefinitionStrategy packageDefinitionStrategy, boolean forbidExisting)	Creates a new injector for the given ClassLoader and ProtectionDomain.

Method Summary

Modifier and Type	Method	Description
Map<String,Class<?>>	injectRaw(Set<String> names, ClassFileLocator classFileLocator)	Injects the given types into the represented class loader.
boolean	isAlive()	Indicates if this class injector is available on the current VM.
static boolean	isAvailable()	Indicates if this class injection is available on the current VM.
static ClassInjector	ofSystemClassLoader()	Creates a class injector for the system class loader.

Constructor Details

UsingReflection

public UsingReflection(ClassLoader classLoader)

Creates a new injector for the given ClassLoader and a default ProtectionDomain and a trivial PackageDefinitionStrategy which does not trigger an error when discovering existent classes.

Parameters:

classLoader - The ClassLoader into which new class definitions are to be injected. Must not be the bootstrap loader.

UsingReflection

public UsingReflection(ClassLoader classLoader,
 @MaybeNull
 ProtectionDomain protectionDomain)

Creates a new injector for the given ClassLoader and a default PackageDefinitionStrategy where the injection of existent classes does not trigger an error.

Parameters:

classLoader - The ClassLoader into which new class definitions are to be injected. Must not be the bootstrap loader.

protectionDomain - The protection domain to apply during class definition.

UsingReflection

public UsingReflection(ClassLoader classLoader,
 @MaybeNull
 ProtectionDomain protectionDomain,
 PackageDefinitionStrategy packageDefinitionStrategy,
 boolean forbidExisting)

Creates a new injector for the given ClassLoader and ProtectionDomain.

Parameters:

classLoader - The ClassLoader into which new class definitions are to be injected.Must not be the bootstrap loader.

protectionDomain - The protection domain to apply during class definition.

packageDefinitionStrategy - The package definer to be queried for package definitions.

forbidExisting - Determines if an exception should be thrown when attempting to load a type that already exists.

Method Details

isAlive

public boolean isAlive()

Indicates if this class injector is available on the current VM.

Returns:

true if this injector is available on the current VM.

injectRaw

public Map<String,Class<?>> injectRaw(Set<String> names,
 ClassFileLocator classFileLocator)

Injects the given types into the represented class loader.

Parameters:

names - The names of the types to load via injection.

classFileLocator - The class file locator to use for resolving binary representations.

Returns:

The loaded types that were passed as arguments.

isAvailable

public static boolean isAvailable()

Indicates if this class injection is available on the current VM.

Returns:

true if this class injection is available.

ofSystemClassLoader

public static ClassInjector ofSystemClassLoader()

Creates a class injector for the system class loader.

Returns:

A class injector for the system class loader.
