Constructor Detail

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,
                       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,
                       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 Detail

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(Map<? extends String,byte[]> types)

Injects the given types into the represented class loader using a mapping from name to binary representation.

Parameters:

types - The types to load via injection.

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.
