Package org.apache.stanbol.entityhub.servicesapi.mapping

Examples of org.apache.stanbol.entityhub.servicesapi.mapping.FieldMapping

Note that a Filter with the pattern '*' no constraint and only an null value as mapping would create a 1:1 copy of the source. TODO: Is it OK to keep an actual implementation in the Service API package? @author Rupert Westenthaler
