Examples of org.apache.openjpa.jdbc.meta.FieldMappingInfo

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 {@link SchemaGroup} used at runtime. Rather, they will be structswith the relevant pieces of information filled in. @author Abe White
