Interface Updatable<E>

All Known Subinterfaces:

MapView<K,V>

All Known Implementing Classes:

AuthorisedChronicleQueueView, ChronicleQueueView, RemoteMapView, VanillaAuthorisedMapView, VanillaMapView

public interface Updatable<E>

This interface assumes that the resource visited is mutable and will be update rather than replaced.

Method Detail

applyTo

@Nullable
default <R> R applyTo(@NotNull
                                @NotNull net.openhft.chronicle.core.util.SerializableFunction<E,R> function)

Apply a function to an Updatable which is assumed to not change the visited in any significant way. This might not trigger an event.

Type Parameters:

R - return type.

Parameters:

function - to apply to derive data from this Updatable.

Returns:

derived data.

asyncUpdate

default void asyncUpdate(@NotNull
                         @NotNull net.openhft.chronicle.core.util.SerializableUpdater<E> updateFunction)

Update an Updatable potentially asynchronously. This function is assumed to update Updatable.

Parameters:

updateFunction - to apply.

syncUpdate

@Nullable
default <R> R syncUpdate(@NotNull
                                   @NotNull net.openhft.chronicle.core.util.SerializableUpdater<E> updateFunction,
                                   @NotNull
                                   @NotNull net.openhft.chronicle.core.util.SerializableFunction<E,R> returnFunction)

Apply a function to update an Updatable and apply a second function to derive some information from it.

Type Parameters:

R - data type to return.

Parameters:

updateFunction - to apply the update.

returnFunction - to derive some data

Returns:

value derived.

applyTo

@Nullable
default <A,R> R applyTo(@NotNull
                                  @NotNull net.openhft.chronicle.core.util.SerializableBiFunction<E,A,R> function,
                                  A arg)

Apply a function to an Updatable which is assumed to not change the visited in any significant way. This might not trigger an event.

Type Parameters:

R - return type.

A - argument type.

Parameters:

function - to apply to derive data from this Updatable.

arg - argument to apply

Returns:

derived data.

asyncUpdate

default <A> void asyncUpdate(@NotNull
                             @NotNull net.openhft.chronicle.core.util.SerializableUpdaterWithArg<E,A> updateFunction,
                             A arg)

Update an Updatable potentially asynchronously. This function is assumed to update Updatable.

Type Parameters:

A - argument type.

Parameters:

arg - argument to apply

updateFunction - to apply.

syncUpdate

@Nullable
default <UA,RA,R> R syncUpdate(@NotNull
                                         @NotNull net.openhft.chronicle.core.util.SerializableUpdaterWithArg<E,UA> updateFunction,
