Examples of org.datanucleus.store.mapped.StatementMappingIndex

org.datanucleus.store.mapped.StatementMappingIndex
Representation of a mapping in a statement (such as JDBC), and its mapping to the associated column(s) or parameters that the mapping relates to. The mapping may be for a field of a class (whether it is a real field or a surrogate), or for a parameter.
- Provides index positions of the column(s) of this field in the result clause of the statement
- Provides parameter position(s) if any of the column(s) are statement parameters, for input
For example, fields of a class in the result clause of a statement.
```
 CLASS                 FIELDNUM     MAPPING            TABLE                COLUMN POSITIONS -----------------     --------     --------------     ----------------     ---------------- class A           -->          -->                --> TABLE_A               { short fieldA;  --> 1        --> ShortMapping   --> COL_FIELDA       --> 1 String fieldB; --> 2        --> StringMapping  --> COL_FIELDB_PART1 --> 2 -->          -->                --> COL_FIELDB_PART2 --> 3 ... }
