◆ Reserve()

template<class T , class ARG_T , class TAlloc = ArrayPoolDefault, class TGrowBy = AkGrowByPolicy_DEFAULT, class TMovePolicy = AkAssignmentMovePolicy<T>>

AKRESULT AkArray< T, ARG_T, TAlloc, TGrowBy, TMovePolicy >::Reserve ( AkUInt32 in_ulReserve )

inline

Ensure preallocation of a number of items.

Reserve() won't change the Length() of the array and does nothing if in_ulReserve is smaller or equal to current Reserved() size.

If an allocation occurs, i.e. in_ulReserve > Reserved(), all iterators and all references to the array elements are invalidated.

覚え書き: When template parameter TGrowBy = AkGrowByPolicy_NoGrow, Reserve() shall only be called if the current reserved size is zero. It should normally only be called once on init.; When template parameter TGrowBy = AkGrowByPolicy_Proportional, inappropriate calls to Reserve(), e.g. calling it before every AddLast(), may increase the number of reallocations and result in decreased performance.
