map
Deprecated.Description copied from interface:ValueHandler
Map the given value and return all mapped columns, or simply return an array of unmapped default columns. The columns should have at least theirName
andJavaType
properties set.- Specified by:

- use as a base to form column name(s); the column names of unmapped columns will automatically be made to fit database limitationsio
- I/O information about mapped columns; you do not have to set this information if returning templatesadapt

toDataStoreValue
Description copied from interface:ValueHandler
Translate the given value to its datastore equivalent. If this value occupies multiple columns, return an object array with one element per column. For relation id columns, return the state manager the column depends on.- Specified by:

toObjectValue
public Object toObjectValue(ValueMapping vm, Object val, OpenJPAStateManager sm, JDBCStore store, JDBCFetchConfiguration fetch) throws SQLException Description copied from interface:ValueHandler
Translate the given datastore value into its Java equivalent. If the value occupies multiple columns, the given object will be an object array with one entry per column. This method is only called ifValueHandler.objectValueRequiresLoad(org.apache.openjpa.jdbc.meta.ValueMapping)
returns true.- Specified by:

- the state manager that owns the value; may be null if loading a projection- Throws:
