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.
