Field Detail

logger

final org.slf4j.Logger logger

The internal slf4j logger.

javaNames

private java.util.List<java.lang.String> javaNames

The name of an attribute in the result class. In the case of embedded classes the can be in fact a list of partial names (name1.name2...nameX). This name can be null. In this case the name of the attribute is the same as the name of the query column or alias output.

dbName

private java.lang.String dbName

The name of a database query output - the column name or the alias name.

sqlType

private SqlType sqlType

The type of an attribute in the result class and/or the database column type. In fact it's a pair of a Hibernate type and/or an internal type.
