◆ m_lazy_nb_source

Int32 Arcane::mesh::IncrementalItemConnectivityContainer::m_lazy_nb_source = 0

Lazy state: this connectivity has never had a connected item.

A mesh registers every connectivity its families could have, whether or not the mesh can use them: on a mesh with no edge, no AMR and no tied interface, the six HParent/HChild ones, FaceFace and the three Edge ones hold nothing for the whole run, and every item created still resizes their two arrays.

While lazy, the two per-source variables stay empty, so isAllocated() is false and the compaction skips them, and both published views are served from the zero buffers of m_lazy_pool, which are never written. The first addConnectedItem() materialises the real arrays. No connectivity is named anywhere: which ones stay empty is discovered at run time.

The flag itself is IncrementalItemConnectivityBase::m_is_lazy, one indirection closer to the caller. Number of source items the lazy views must cover

◆ m_lazy_pool

LazyMemoryPool Arcane::mesh::IncrementalItemConnectivityContainer::m_lazy_pool

static

Zero buffers read by the lazy views.

A connectivity republishes from its own notify path, when its own localIds outgrow the view it published, so its view always covers its own items without depending on what another thread did.
