Interface DOMRpcAvailabilityListener

All Superinterfaces:

EventListener

public interface DOMRpcAvailabilityListener
extends EventListener

An EventListener used to track RPC implementations becoming (un)available to a DOMRpcService.

Method Summary

Modifier and Type	Method and Description
default boolean	acceptsImplementation(DOMRpcImplementation impl) Implementation filtering method.
void	onRpcAvailable(@NonNull Collection<DOMRpcIdentifier> rpcs) Method invoked whenever an RPC type becomes available.
void	onRpcUnavailable(@NonNull Collection<DOMRpcIdentifier> rpcs) Method invoked whenever an RPC type becomes unavailable.

Method Detail

onRpcAvailable

void onRpcAvailable(@NonNull Collection<DOMRpcIdentifier> rpcs)

Method invoked whenever an RPC type becomes available.

Parameters:

rpcs - RPC types newly available

onRpcUnavailable

void onRpcUnavailable(@NonNull Collection<DOMRpcIdentifier> rpcs)

Method invoked whenever an RPC type becomes unavailable.

Parameters:

rpcs - RPC types which became unavailable

acceptsImplementation

default boolean acceptsImplementation(DOMRpcImplementation impl)

Implementation filtering method. This method is useful for forwarding RPC implementations, which need to ensure they do not re-announce their own implementations. Without this method a forwarder which registers an implementation would be notified of its own implementation, potentially re-exporting it as local -- hence creating a forwarding loop.

Parameters:

impl - RPC implementation being registered

Returns:

False if the implementation should not be reported, defaults to true.
