Interface EntryPointResolverSet

All Known Implementing Classes:

DefaultEntryPointResolverSet, LegacyEntryPointResolverSet

public interface EntryPointResolverSet

EntryPointResolver resolves a method to call on the given service object when an event is received. This object maintains a set of Resolvers that will be used in order to resolve an entrypoint on a service object until one is found or until the set is exhausted. Note that there is a one-to-one mapping from component to EntryPointResolverSet. Each component must get a separate set with EntryPointResolver instances that are not shared. An EntryPointResolver is allowed to cache state and can assume the component will always be of the the same type.

Method Summary

Modifier and Type	Method and Description
void	addEntryPointResolver(EntryPointResolver resolver) Will add a resolver to the list of resolvers to invoke on a compoent.
Object	invoke(Object component, MuleEventContext context, Event.Builder eventBuilder) Will attempt to invoke the component by looping through all EntryPointResolver instances registered on this set until a match is found
boolean	removeEntryPointResolver(EntryPointResolver resolver) Removes a resolver from the list

Method Detail

invoke

Object invoke(Object component,
              MuleEventContext context,
              Event.Builder eventBuilder)
       throws Exception

Will attempt to invoke the component by looping through all EntryPointResolver instances registered on this set until a match is found

Parameters:

component - the component to invoke

context - the current event context, this is used to figure out which method to call on the component

Returns:

the result of the invocation

Throws:

Exception - if the invocation itself or an EntryPointResolver fails

addEntryPointResolver

void addEntryPointResolver(EntryPointResolver resolver)

Will add a resolver to the list of resolvers to invoke on a compoent. Implementations must maintain an ordered list of resolvers

Parameters:

resolver - the resolver to add

removeEntryPointResolver

boolean removeEntryPointResolver(EntryPointResolver resolver)

Removes a resolver from the list

Parameters:

resolver - the resolver to remove

Returns:

true if the resolver was found and removed from the list
