Method Detail

mapRow

public java.lang.Object mapRow(java.sql.ResultSet resultSet,
                               int rowIndex)

Map a row from the db. This essentially builds an appropriate object tree using the xml schema for the returned result set. If any members are related fields new recursive finders are created and appended to the tree.

This routine operates in two modes, depending on which constructor was called a) recursive query mode (creates new instances for each row and pulls recursively to create a full tree) b) remap mode (uses an existing instance and replaces the data. Does not act recursively).

Parameters:

resultSet -

rowIndex -

Returns:

Object

processRow

protected void processRow(java.sql.ResultSet resultSet,
                          int rowIndex,
                          java.util.ArrayList resultsList)

Common code used for processing a particular row.

Parameters:

resultSet -

rowIndex -

resultsList -
