Package org.datanucleus.store.rdbms.mapping.java

Package providing mappings for all supported Java types in DataNucleus. A JavaTypeMapping provides a mapping from the Java type to the associated ColumnMapping type(s). At the class side we have a field, and at the datastore side we have the column(s).

SerialisedValuePCMapping	Mapping for a serialised persistable object being the value of a Map.
ShortMapping	Mapping for the Short type.
SingleCollectionMapping	Maps single collection elements as 1-1 instead of 1-N, by wrapping and reusing the JavaTypeMappings and member metadata of the element types.
SingleFieldMapping	Simple mapping for a java field mapping to a single column.
SingleFieldMultiMapping	Mapping to represent a field that is mapped to multiple datastore columns.

SqlTimestampMapping	SCO Mapping for a java.sql.Timestamp type.
StringMapping	Mapping for a String type.
SubclassPCMapping	Mapping for a field that stores a PC object that uses "subclass-table" inheritance and where this is mapped in the datastore as a separate FK for each subclass.
TemporalMapping	Abstract base mapping for all temporal types.
TypeConverterMapping	Mapping where the member has its value converted to/from some storable datastore type using a TypeConverter.
TypeConverterMultiMapping	Mapping where the member has its value converted to/from some storable datastore type using a TypeConverter to multiple columns.
UUIDMapping	Mapping for fields of type java.util.UUID.
