Wraps a target instance and an AutoCloseable delegate into a proxy instance that closes both when wrapper close method called.

Type Parameters:

T - The generic AutoCloseable wrapping interface

Parameters:

proxyTarget - The (never null) target instance - if not AutoCloseable then it's close() method will not be invoked (i.e., only the delegate)

type - The target wrapping interface

delegate - The (never null) delegate to close. Note: the delegate is closed after the target instance.

Returns:

The wrapping proxy
