Columns Selection DSL

Select or express columns using the Columns Selection DSL.

This DSL is initiated by a Columns Selector lambda, which operates in the context of the Columns Selection DSL and expects you to return a SingleColumn or ColumnSet (so, a ColumnsResolver). This is an entity formed by calling any (combination) of the functions in the DSL that is or can be resolved into one or more columns.

The Columns Selection DSL allows using Extension Properties for specifying columns type- and name-safe.

Check out: Columns Selection DSL Grammar

    

See Column Selectors on the documentation website.

For example:

df.select{ length andage }

df.select{ cols(1..5) }

df.select{ colsOf<Double>() }

open fun <R> ColumnPath.select(selector: ColumnsSelector<*, R>): ColumnSet<R>
open fun <C, R> SingleColumn<DataRow<C>>.select(selector: ColumnsSelector<C, R>): ColumnSet<R>

Perform a selection of columns using the Columns Selection DSL on any ColumnGroup. This is more powerful than the cols filter, because now all operations of the DSL are at your disposal.

open fun <C> ColumnSet<C>.simplify(): ColumnSet<C>

Given a this ColumnSet, simplify simplifies the structure by removing columns that are already present in column groups, returning only these groups plus columns not belonging in any of the groups.
