Syntax

namespace AlgoImpl
{
    template<typename T, typename ProjectionType, typename PredicateType>
    void AlgoImpl::LegacySortInternal
    (
        T * First,
        int32 Num,
        ProjectionType Projection,
        PredicateType Predicate
    )
}

Remarks

Sort elements using user defined predicate class. The sort is unstable, meaning that the ordering of equal items is not necessarily preserved. This is the internal sorting function used by Sort overrides. This used to be Algo::Sort and is now considered legacy.

Parameters

Parameter	Description
First	pointer to the first element to sort
Num	the number of items to sort
Predicate	predicate class
