    public interface EnvironmentCapable

Interface indicating a component contains and makes available an `Environment` object.

All Spring application contexts are EnvironmentCapable, and the interface is used primarily for performing `instanceof` checks in framework methods that accept BeanFactory instances that may or may not actually be ApplicationContext instances in order to interact with the environment if indeed it is available.

As mentioned, `ApplicationContext` extends EnvironmentCapable, and thus exposes a `getEnvironment()` method; however, `ConfigurableApplicationContext` redefines `getEnvironment()` and narrows the signature to return a `ConfigurableEnvironment`. The effect is that an Environment object is 'read-only' until it accessed from a ConfigurableApplicationContext, at which point it too may be configured.
