Optional Element Summary

Modifier and Type	Optional Element and Description
Class<? extends AttributesTypeResolver>	attributes Specifies the AttributesTypeResolver which should be used to resolve the type of the Message#getAttributes() of the output message.
Class<? extends OutputTypeResolver>	output Specifies the OutputTypeResolver which should be used to resolve the type of the value which will go into the payload of the output message.

Element Detail

output

public abstract Class<? extends OutputTypeResolver> output

Specifies the OutputTypeResolver which should be used to resolve the type of the value which will go into the payload of the output message.

Always keep in mind that this should resolve to a single unitary type. That means that for operations which return collections, this should not return an ArrayType but the type of the items inside the collection.

So, if the operation returns List<Apple>, this should return a MetadataType for the Apple. Also, if the operation returns List<Result<Apple, AppleAttributes>>, it still should only return the Apple's metadata.

Returns:

the associated OutputTypeResolver for the annotated Component

Default:

org.mule.sdk.api.metadata.NullMetadataResolver.class

attributes

public abstract Class<? extends AttributesTypeResolver> attributes

Specifies the AttributesTypeResolver which should be used to resolve the type of the Message#getAttributes() of the output message.

Always consider that this resolver should be consistent with the one returned by output().

So, if the operation returns List<Apple>, this should return a MetadataType for attributes which describe the Apple, not the list. . Also, if the operation returns List<Result<Apple, AppleAttributes>>, it still should only describe AppleAttributes.

Returns:

the associated AttributesTypeResolver for the annotated Component

Default:

org.mule.sdk.api.metadata.NullMetadataResolver.class
