resultType - must not be null.

map

<R> RowsFetchSpec<R> map(Function<Row,R> mappingFunction)

Configure a result mapping function.

Type Parameters:

R - result type.

Parameters:

mappingFunction - must not be null.

Returns:

a FetchSpec for configuration what to fetch. Guaranteed to be not null.

map

<R> RowsFetchSpec<R> map(BiFunction<Row,RowMetadata,R> mappingFunction)

Configure a result mapping function.

Type Parameters:
