DBBeanListFactoryImpl

public DBBeanListFactoryImpl(Constructor<T> constructor,
 List<? extends DBColumnExpr> constructorParams,
 List<? extends DBColumnExpr> setterColumns)

Constructs a DBRecordListFactoryImpl based on an DBRecord constructor

Parameters:

constructor - the constructor to be used to create the bean

constructorParams - (optional) the columns to be used for the constructor. Must match the constructor!

setterColumns - (optional) the columns to be set through setter methods. List may include constructorParams

DBBeanListFactoryImpl

public DBBeanListFactoryImpl(Class<T> beanType,
 List<? extends DBColumnExpr> selectColumns)

Constructs a DBRecordListFactoryImpl based on an DBRecord class

Parameters:

beanType - the bean type to be instantiated

selectColumns - (optional) the columns to be selected
