Detailed Description

template<typename ItemType, typename SizeType>
class OnixS::CME::MarketData::VectorOverArray< ItemType, SizeType >

Implements vector-like container over built-in array of fixed size being referenced.

Member Function Documentation

Item& at ( Index  index) const

inline

Accesses to item by index checking access bounds.

Item& extrudingInsert ( Index  index)

inline

Inserts new item to given position.

Items under higher indices are moved back. Last item is extruded thus keeping size of or container constant.

Returns

Reference to an item at requested position for further update.

void resize ( Size  newSize, const Item &  item = Item()  )

inline

Resizes container.

If vector is enlarged, new items constructed as copies of given instance.

void size ( Size  newSize)

inline

Changes size of container without deleting or constructing items (suitable for POD items).
