Class ResultSetAccess

  extended by de.mathema.pride.ResultSetAccess

public class ResultSetAccess
extends java.lang.Object

This class holds meta information about access methods to JDBC result sets. It is required for PriDE's generic way of fetching record fields from an SQL query result. By default, the class is initialized by its init() method on the first call of #getAccessMethod(String) or #getIndexAccessMethod(String) which in turn are called by the constructors of class RecordDescriptor. However, you might be required to change the default mappings according to your driver's abilities. E.g. the default MySQL JDBC driver turned out not to support making timestamps from ordinary date strings.
