IterTools_test Class Reference

Description

Test:

build combined and filtering iterators with the help of lib::IterTool.

Check correct behaviour of the resulting iterators and verify they fulfil the Lumiera Forward Iterator concept

Todo:

implement more iterator tools.... see Ticket #347

Member Function Documentation

verify_filterExtension()

void verify_filterExtension ( )

inlineprivate

Test:

verify the ability to extend a filter condition while in the middle of an ongoing iteration.

Typically this means sharpening the filter condition and thus making the filter more restrictive, filtering away more elements of the source stream. But through the ability to add disjunctive and negated clauses, it is also possible to weaken the filter condition

Note

in case of a weakened filter condition, there is no reset of the source iterator, i.e. we don't re-evaluate from start, but just from current head.

verify_filterRepetitions()

void verify_filterRepetitions ( )

inlineprivate

Test:

verify the helper to filter duplicate elements emitted by an source iterator.

This test creates a sequence of numbers with random repetitions.

buildWrappedSingleElement()

void buildWrappedSingleElement ( )

inlineprivate

Test:

wrap an arbitrary single element as pseudo-iterator

verifyComparisons()

void verifyComparisons ( IT const &  ii )

inlineprivate

Test:

verify equality handling and NIL detection for the given iterator/wrapper handed in
