Uses of Callback in org.eclipse.jetty.util

Subinterfaces of Callback in org.eclipse.jetty.util

Modifier and Type	Interface	Description
static interface	Blocker.Callback
static interface	Callback.Completing	A Callback implementation that calls the Callback.Completing.completed() method when it either succeeds or fails.

Classes in org.eclipse.jetty.util that implement Callback

Modifier and Type	Class	Description
static class	Callback.Completable	A CompletableFuture that is also a Callback.
static class	Callback.Nested	Nested Completing Callback that completes after completing the nested callback
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 asynchronous task to be broken into smaller asynchronous sub-tasks using iteration rather than recursion.
class	IteratingNestedCallback	Iterating Nested Callback.
class	SharedBlockingCallback.Blocker	Deprecated. A Closeable Callback.

Fields in org.eclipse.jetty.util declared as Callback

Modifier and Type	Field	Description
static final Callback	Callback.NOOP	Instance of Callback that can be used when the callback methods need an empty implementation without incurring in the cost of allocating a new Callback object.
static final Callback	Callback.NOT_CALLED	Instance of Callback to use in cases where it is known that no one will complete the callback.

Methods in org.eclipse.jetty.util that return Callback

Modifier and Type	Method	Description
static Callback	Callback.combine(Callback cb1, Callback cb2)
static Callback	Callback.from(Runnable completed)	Creates a callback that runs completed when it succeeds or fails
static Callback	Callback.from(Runnable success, Consumer<Throwable> failure)	Creates a callback from the given success and failure lambdas.
static Callback	Callback.from(Runnable completed, Callback callback)	Creates a nested callback that runs completed before completing the nested callback.
static Callback	Callback.from(CompletableFuture<?> completable)	Creates a non-blocking callback from the given incomplete CompletableFuture.
static Callback	Callback.from(CompletableFuture<?> completable, Invocable.InvocationType invocationType)	Creates a callback from the given incomplete CompletableFuture, with the given blocking characteristic.
static Callback	Callback.from(Callback callback, Runnable completed)	Creates a nested callback that runs completed after completing the nested callback.
static Callback	Callback.from(Callback callback, Throwable cause)	Creates a nested callback which always fails the nested callback on completion.
static Callback	Callback.from(Callback callback, Consumer<Throwable> completed)	Creates a nested callback that runs completed after completing the nested callback.
static Callback	Callback.from(Callback callback1, Callback callback2)	Creates a callback which combines two other callbacks and will succeed or fail them both.
static Callback	Callback.from(Invocable.InvocationType invocationType, Runnable completed)	Creates a Callback with the given invocationType, that runs the given Runnable when it succeeds or fails.
static Callback	Callback.from(Invocable.InvocationType invocationType, Runnable success, Consumer<Throwable> failure)	Creates a callback with the given InvocationType from the given success and failure lambdas.
Callback	Callback.Nested.getCallback()
Callback	Callback.Combination.newCallback()	Create a new Callback as part of this combination.
static <T> Callback	Promise.Invocable.toCallback(Promise.Invocable<T> promise, T result)	Returns a new Callback that, when it is completed, completes the given promise.

Methods in org.eclipse.jetty.util with parameters of type Callback

Modifier and Type	Method	Description
static Callback	Callback.combine(Callback cb1, Callback cb2)
static Callback.Completable	Callback.Completable.from(Callback callback)	Creates a completable future given a callback.
static Callback	Callback.from(Runnable completed, Callback callback)	Creates a nested callback that runs completed before completing the nested callback.
static Callback	Callback.from(Callback callback, Runnable completed)	Creates a nested callback that runs completed after completing the nested callback.
static Callback	Callback.from(Callback callback, Throwable cause)	Creates a nested callback which always fails the nested callback on completion.
static Callback	Callback.from(Callback callback, Consumer<Throwable> completed)	Creates a nested callback that runs completed after completing the nested callback.
static Callback	Callback.from(Callback callback1, Callback callback2)	Creates a callback which combines two other callbacks and will succeed or fail them both.
void	Scanner.scan(Callback complete)	Get the scanner to perform a scan cycle as soon as possible and call the Callback when the scan is finished or failed.
