Syntax

template<typename ElementType>
struct TEvaluationTreeEntryContainer

Remarks

Sub-divided container type that allocates smaller 'buckets' of capacity within a single allocation. New entries, or entries needing additional capacity are reallocated at the end of the array to avoid reallocation or shuffling. Memory footprint can be compacted once the container is fully built using TEvaluationTreeEntryContainer::Compact Designed specifically to solve allocation cost incurred when compiling very large trees of sequence data. Restrictions: Container can only ever add entries, never remove
