@FunctionalInterface
public interface ExcerptListener

A listener interface for receiving events when excerpts are encountered.

Method Summary

Modifier and Type	Method and Description

void	onExcerpt(@NotNull Wire wire, long index) Invoked per each encountered excerpt.

Method Detail

onExcerpt

void onExcerpt(@NotNull
               @NotNull Wire wire,
               long index)
        throws net.openhft.chronicle.core.io.InvalidMarshallableException

Invoked per each encountered excerpt.

If this method throws an Exception, it is relayed to the call site. Therefore, care should be taken to minimise the probability of throwing Exceptions.

Parameters:

wire - representing access to the excerpt that was stored (non-null).

index - in the queue where the except was placed (non-negative)

Throws:

net.openhft.chronicle.core.io.InvalidMarshallableException

andThen

@NotNull
default @NotNull ExcerptListener andThen(@NotNull
                                                  @NotNull ExcerptListener after)

Returns a composed ExcerptListener that first accepts excerpts to this ExcerptListener, and then accepts excerpts to the after ExcerptListener. If execution of either listener throws an exception, it is relayed to the caller of the composed ExcerptListener.

Care should be taken to only create composed listeners that are performant.

Parameters:

after - the ExcerptListener to accept excerpts after this ExcerptListener

Returns:

a composed ExcerptListener

Throws:

NullPointerException - if after is null
