Class StatementExpressionIndex

java.lang.Object
  org.jpox.store.StatementExpressionIndex

public class StatementExpressionIndex
extends java.lang.Object

Maintain an index for the mapping field vs columns in a JDBC statement. Each field for a Request (in a Statement) must have one instance of this containing the field Number + Mapping + the columns

 
 e.g.
 CLASS                 FIELDNUMBER     MAPPING            TABLE                EXPRESSION INDEX (JDBC)
 -----------------     -----------     --------------     ----------------     ----------------
 class A           -->             -->                --> TABLE_A            
 {
    int fieldA;    --> 1           --> IntegerMapping --> COL_FIELDA       --> 1
    String fieldB; --> 2           --> StringMapping  --> COL_FIELDB_PART1 --> 2
                   -->             -->                --> COL_FIELDB_PART2 --> 3
    ...
 }
