FunctionalOperations

Usage

use FunctionalOperations;

The FunctionalOperations module provides operations that act on iterators in a functional programming style.

iter _iteratorRecord.map(fn)

Apply fn to each element yielded by this iterator and yield the value returned by fn. fn must take a single argument and return a value.

iter _iteratorRecord.filter(fn)

Apply fn to each element yielded by this iterator and yield the values it returns true for. fn must take a single argument and return a boolean value.

proc _iteratorRecord.consume(fn)

Apply fn to each element yielded by this iterator and ignore the return value from fn if any.
