Interface PartialTypeKeysResolver<T>

All Superinterfaces:

NamedTypeResolver, TypeKeysResolver

public interface PartialTypeKeysResolver<T>
extends TypeKeysResolver

A TypeKeysResolver that can handle the resolution of multi-level MetadataKey in a lazy way. On each invocation, this resolver will perform the resolution of one more level of the MetadataKey tree, based on the configuration of the previous levels.

Since:

1.1

Method Detail

resolveChilds

MetadataKey resolveChilds(MetadataContext context,
                          T partial)
                   throws MetadataResolvingException,
                          ConnectionException

Further resolves the of types that can be described based on a partial configuration of the Type descriptor, representing them as a multi level MetadataKey. For example, if we have a location key composed by:

 
  Location: {
    continent,
    country,
    city
  }
 
 

Were the Continent is required to resolve the Country, and the Country is required to resolve the City, this resolveChilds(org.mule.runtime.api.metadata.MetadataContext, T) method will be invoked with the Location configuration available so far. In this case, possible values for the partial parameter of this method are Location: { continent } and Location: { continent, country }

Parameters:

context - MetadataContext of the Metadata resolution

partial - the current, partial representation of the type key.

Returns:

A multi level MetadataKey of representing the available types

Throws:

MetadataResolvingException - if an error occurs during the MetadataKey building. See FailureCode for possible MetadataResolvingException reasons

ConnectionException - if an error occurs when using the connection provided by the MetadataContext
