Description copied from interface: StaticAttributeTag

A function that modifies an existing StaticTableSchema.Builder when this tag is applied to a specific attribute. This will be used by the StaticTableSchema to capture all the metadata associated with tagged attributes when constructing the table schema.

Specified by:

modifyMetadata in interface StaticAttributeTag

Parameters:

attributeName - The name of the attribute this tag has been applied to.

attributeValueType - The type of the attribute this tag has been applied to. This can be used for validation, for instance if you have an attribute tag that should only be associated with a string.

Returns:

a consumer that modifies an existing StaticTableSchema.Builder.
