Class ResultSetParseHelper

java.lang.Object

org.sodeac.common.jdbc.ResultSetParseHelper

All Implemented Interfaces:

AutoCloseable

public class ResultSetParseHelper
extends Object
implements AutoCloseable

A helper class to convert data from more or less complex linked ResultSet to a tree like / object based data structure.

The rows are divided into clusters. After all parse phases process a cluster, the next cluster is processed by parse phases.

The requirements:
1. The processed ResultSet must be scrollable
2. The data for a main object must be delivered in consecutively rows
3. Each object requires an unique-key-column
4. The main configurations of all project phases must specify the same key column
