实现Callback的com.firefly.utils.concurrent中的类

限定符和类型	类和说明
static class	Callback.Completable A CompletableFuture that is also a Callback.
static class	Callback.Nested
class	CompletableCallback A callback to be used by driver code that needs to know whether the callback has been succeeded or failed (that is, completed) just after the asynchronous operation or not, typically because further processing depends on the callback being completed.
class	CountingCallback A callback wrapper that succeeds the wrapped callback when the count is reached, or on first failure.
class	FutureCallback
class	IteratingCallback This specialized callback implements a pattern that allows a large job to be broken into smaller tasks using iteration rather than recursion.
class	IteratingNestedCallback Iterating Nested Callback.
class	SharedBlockingCallback.Blocker A Closeable Callback.

声明为Callback的com.firefly.utils.concurrent中的字段

限定符和类型	字段和说明
static Callback	Callback.NOOP Instance of Adapter that can be used when the callback methods need an empty implementation without incurring in the cost of allocating a new Adapter object.

static Callback	Callback.from(CompletableFuture<?> completable) Creates a non-blocking callback from the given incomplete CompletableFuture.
static Callback	Callback.from(CompletableFuture<?> completable, boolean blocking) Creates a callback from the given incomplete CompletableFuture, with the given blocking characteristic.
