DefaultAsyncReference

public DefaultAsyncReference(net.kuujo.copycat.resource.internal.ResourceManager context)

Method Detail

get

public CompletableFuture<T> get()

Description copied from interface: AsyncReferenceProxy

Gets the value.

Specified by:

get in interface AsyncReferenceProxy<T>

Returns:

A completable future to be completed with the current reference value.

set

public CompletableFuture<Void> set(T value)

Description copied from interface: AsyncReferenceProxy

Sets the value.

Specified by:

set in interface AsyncReferenceProxy<T>

Parameters:

value - The value to set.

Returns:

A completable future to be completed once the value has been set.

getAndSet

public CompletableFuture<T> getAndSet(T value)

Description copied from interface: AsyncReferenceProxy

Sets and gets the value.

Specified by:

getAndSet in interface AsyncReferenceProxy<T>

Parameters:

value - The new value to set.

Returns:

A completable future to be completed with the previous value.

compareAndSet

public CompletableFuture<Boolean> compareAndSet(T expect,
                                                T update)

Description copied from interface: AsyncReferenceProxy

Sets the value if the current value == the expected value.

Specified by:

compareAndSet in interface AsyncReferenceProxy<T>

Parameters:

expect - The expected value.

update - The updated value.

Returns:

A completable future to be completed once the operation is complete with a boolean indicating whether the updated value was set.

open

public CompletableFuture<AsyncReference<T>> open()

Specified by:

open in interface net.kuujo.copycat.util.Managed<AsyncReference<T>>

close

public CompletableFuture<Void> close()

Specified by:

close in interface net.kuujo.copycat.util.Managed<AsyncReference<T>>
