Overrides:

getFactoryName in class GenericFactory

Returns:

The name of this factory

getQueryExpression

public QueryExpression getQueryExpression()

Description copied from interface: PersistenceFactory

Returns a new empty query expression suitable for the underlying SQL engine. The implementation will construct SQL query statements in the preferred syntax.

getQueryExpression in class GenericFactory

Returns:

New empty query expression

adjustSqlType

public java.lang.Class adjustSqlType(java.lang.Class sqlType)
