/**
 * An object that can create new instances of various types. An {@code Instantiator}, depending on its implementation and configuration, may provide
 * a number of capabilities. Some examples:
 *
 * 
    *
  • An implementation may decorate the instances in some fashion, for example to mix in the Groovy DSL, and so may return a subclass of the requested type. * *
  • An implementation may accept abstract classes or interfaces and provide implementations for the missing pieces, for example providing an implementation of ExtensionAware. * *
  • An implementation may provide injection of services and other dependencies into the instances it creates, for example exposing services via a getter method. * *
* *

An implementation is not required to support any of these features. Implementations must be thread-safe. * *

A service of this type is available in all scopes. However, the recommended way to receive an {@code Instantiator} is via a {@link org.gradle.internal.instantiation.InstantiatorFactory}.
