Parameters:

comparator - the comparator to be used.

Returns:

an operator containing the sorted structure as target object.

sortBy

SortableOperator<T> sortBy(IFunction<? super T,?> by)

Sorts the elements of the structure according to the result of executing the specified function.

Parameters:

by - the function to be executed in order to obtain the compared object
