Compares the attributes of a AttributeDraft and a Attribute to build either a SetAttribute or a SetAttributeInAllVariants.

If the attribute is sameForAll a SetAttributeInAllVariants is built. Otherwise, a SetAttribute is built.

If both the AttributeDraft and the Attribute have identical values, then no update action is needed and hence an empty List is returned.

Parameters:

variantId - the id of the variant of that the attribute belong to. It is used only in the error messages if any.

oldProductVariantAttribute - the Attribute which should be updated.

newProductVariantAttribute - the AttributeDraft where we get the new value.

attributeMetaData - a map of attribute name -> AttributeMetaData; which defines attribute information: its name, whether a value is required or not and whether it has the constraint "SameForAll" or not.

Returns:

A filled optional with the update action or an empty optional if the attributes are identical.

Throws:

BuildUpdateActionException - thrown if attribute as not found in the attributeMetaData or if the attribute is required and the new value is null.
