Functions

drop

open fun ColumnsSelectionDsl<*>.drop(n: Int): ColumnSet<*>

open fun <C> ColumnSet<C>.drop(n: Int): ColumnSet<C>

This operation collects all columns from this except the first n into a ColumnSet.

dropCols

open fun String.dropCols(n: Int): ColumnSet<*>

open fun KProperty<*>.~~dropCols~~(n: Int): ColumnSet<*>

open fun ColumnPath.dropCols(n: Int): ColumnSet<*>

open fun SingleColumn<DataRow<*>>.dropCols(n: Int): ColumnSet<*>

This operation collects all columns from this except the first n into a ColumnSet.

dropColsWhile

open fun String.dropColsWhile(predicate: (ColumnWithPath<*>) -> Boolean): ColumnSet<*>

open fun KProperty<*>.~~dropColsWhile~~(predicate: (ColumnWithPath<*>) -> Boolean): ColumnSet<*>

open fun ColumnPath.dropColsWhile(predicate: (ColumnWithPath<*>) -> Boolean): ColumnSet<*>

open fun SingleColumn<DataRow<*>>.dropColsWhile(predicate: (ColumnWithPath<*>) -> Boolean): ColumnSet<*>

This operation drops the first columns from this while they adhere to the predicate, stops as soon as it encounters one that does not, and collects the remaining columns into a ColumnSet.

dropLast

open fun ColumnsSelectionDsl<*>.dropLast(n: Int = 1): ColumnSet<*>

open fun <C> ColumnSet<C>.dropLast(n: Int = 1): ColumnSet<C>

This operation collects all columns from this except the last n into a ColumnSet.

dropLastCols

open fun String.dropLastCols(n: Int): ColumnSet<*>

open fun KProperty<*>.~~dropLastCols~~(n: Int): ColumnSet<*>

open fun ColumnPath.dropLastCols(n: Int): ColumnSet<*>

open fun SingleColumn<DataRow<*>>.dropLastCols(n: Int): ColumnSet<*>

This operation collects all columns from this except the last n into a ColumnSet.

dropLastColsWhile

open fun String.dropLastColsWhile(predicate: (ColumnWithPath<*>) -> Boolean): ColumnSet<*>
