Class ValueMappingInfo

java.lang.Object

org.apache.openjpa.jdbc.meta.MappingInfo

org.apache.openjpa.jdbc.meta.ValueMappingInfo

All Implemented Interfaces:

Serializable

public class ValueMappingInfo
extends MappingInfo

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.
