◆ reserveMemoryForNbSourceItems()

void Arcane::IIncrementalItemSourceConnectivity::reserveMemoryForNbSourceItems	(	Int32	n,
		bool	pre_alloc_connectivity )

virtual

Reserves memory for n source entities.

Calling this method is optional but prevents multiple reallocations during successive calls to notifySourceItemAdded().

If pre_alloc_connectivity is true, it also pre-allocates the list of connectivities based on the value of preAllocatedSize(). For example, if preAllocatedSize() is 4 and n is 10000, we will pre-allocate for 40000 connectivities. To avoid unnecessary memory overconsumption, connectivities should only be pre-allocated if we are sure we will use them.
