Class GregorianCalendarMapping
java.lang.Object
org.datanucleus.store.rdbms.mapping.java.JavaTypeMapping
org.datanucleus.store.rdbms.mapping.java.SingleFieldMultiMapping
org.datanucleus.store.rdbms.mapping.java.GregorianCalendarMapping
Maps the class fields of a GregorianCalendar to column(s).
We default to a single column (timestamp), but allow the option of persisting to 2 columns (timestamp millisecs and timezone).
JPOX traditionally supported persistence to 2 columns.
TODO Remove this and use converters for the different options : (Long, String), (Timestamp).

initialize
public void initialize(org.datanucleus.metadata.AbstractMemberMetaData fmd, Table table, org.datanucleus.ClassLoaderResolver clr) Description copied from class:JavaTypeMapping
Initialize this JavaTypeMapping for the supplied table and field/property metadata. Subclasses should override this method to perform any datastore initialization operations. Assumes the "roleForMember" is already set- Overrides:
initialize
in classJavaTypeMapping
- Parameters:
fmd
- MetaData for the field/property to be mapped (if any)table
- The table storing this mapping (if any)clr
- the ClassLoaderResolver
-
initialize
Description copied from class:JavaTypeMapping
Initialise this JavaTypeMapping with the given StoreManager for the given type. Used when the mapping is for a parameter in a query. This will not set the "mmd" and "datastoreContainer" parameters. If these are required for usage of the mapping then you should call setFieldInformation(AbstractMemberMetaData, DatastoreContainerObject) below. Subclasses should override this method to perform any datastore initialization operations.- Overrides:
initialize
in classJavaTypeMapping
- Parameters:
storeMgr
- The Datastore Adapter that this Mapping should use.type
- The Class that this mapping maps to the database.
-
addColumns
protected void addColumns() -
getJavaType
Description copied from class:JavaTypeMapping
Accessor for the java type being mapped. This is the java type that the mapping represents. Some examples :- if the field is of type "MyClass" then the mapping will be OIDMapping (or subclass) the javaType will be OID, and the type will be MyClass.
- if the field is of type "int" then the mapping will be IntegerMapping, the javaType will be Integer, and the type will be int.
- Specified by:
getJavaType
in classJavaTypeMapping
- Returns:
- The java type
-
getJavaTypeForColumnMapping
Accessor for the name of the java-type actually used when mapping the particular column. This java-type must have an entry in the datastore mappings.- Overrides:
getJavaTypeForColumnMapping
in classSingleFieldMultiMapping
- Parameters:
index
- requested column index.- Returns:
- the name of java-type for the requested column.
-
getValueForColumnMapping
public Object getValueForColumnMapping(org.datanucleus.NucleusContext nucleusCtx, int index, Object value) Method to return the value to be stored in the specified datastore index given the overall value for this java type.- Overrides:
getValueForColumnMapping
in classJavaTypeMapping
- Parameters:
nucleusCtx
- Contextindex
- The datastore indexvalue
- The overall value for this java type- Returns:
- The value for this datastore index
-
setObject
public void setObject(org.datanucleus.ExecutionContext ec, PreparedStatement ps, int[] exprIndex, Object value) Description copied from class:JavaTypeMapping
Sets avalue
intodatastoreStatement
at position specified byexprIndex
.- Overrides:
setObject
in classJavaTypeMapping
- Parameters:
ec
- ExecutionContextps
- PreparedStatementexprIndex
- the position of the value in the statementvalue
- the value
-
getObject
Description copied from class:JavaTypeMapping
Obtains a value fromdatastoreResults
at position specified byexprIndex
.- Overrides:
getObject
in classJavaTypeMapping
- Parameters:
ec
- ExecutionContextresultSet
- ResultSetexprIndex
- the position of the value in the result- Returns:
- the value
