org.apache.openjpa.jdbc.meta.ValueMappingInfo
public class ValueMappingInfo
Information about the mapping from a field value 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.
