Class FieldMappingInfo

java.lang.Object
  org.apache.openjpa.jdbc.meta.MappingInfo
      org.apache.openjpa.jdbc.meta.FieldMappingInfo

All Implemented Interfaces:

Serializable, Commentable

public class FieldMappingInfo
extends MappingInfo
implements Commentable

Information about the mapping from a field to the schema, in raw form. The columns and tables used in mapping info will not be part of the SchemaGroup used at runtime. Rather, they will be structs with the relevant pieces of information filled in.
