org.datanucleus.store.types.jodatime.rdbms.mapping.JodaIntervalMapping

public class JodaIntervalMapping
extends org.datanucleus.store.rdbms.mapping.java.SingleFieldMultiMapping

SCO Mapping for org.joda.time.Interval type. Can be persisted using either

• Single column using a String mapping.
• Two columns using Timestamp mappings for the start/end components

See http://joda-time.sourceforge.net/ TODO Remove this and use TypeConverters

addColumns

protected void addColumns()

getJavaTypeForColumnMapping

public String getJavaTypeForColumnMapping(int index)

Accessor for the name of the java-type actually used when mapping the particular column. This java-type must have an entry in the column mappings.

Overrides:

getJavaTypeForColumnMapping in class org.datanucleus.store.rdbms.mapping.java.SingleFieldMultiMapping

Parameters:

index - requested column index.

Returns:

the name of java-type for the requested column.

getJavaType

public Class getJavaType()

Specified by:

getJavaType in class org.datanucleus.store.rdbms.mapping.java.JavaTypeMapping

getValueForColumnMapping

public Object getValueForColumnMapping(org.datanucleus.NucleusContext nucleusCtx,
                                       int index,
                                       Object value)
