Nested Class Summary

Nested Classes

Modifier and Type	Interface	Description
static interface	Column.ColumnDefiner<T>	Provides ColumnDefinition.Builder instances.
static interface	Column.Converter<T,C>	Converts to and from SQL values, such as integers being used to represent booleans in a database. By default a Column.Converter is not expected to handle null values, with null values automatically converted to/from null column values. If a Column.Converter needs to handle null values as well as non-null values Column.Converter.handlesNull() must be overridden to return true.
static interface	Column.Fetcher<C>	Fetches a single value from a result set.
