◆ shrinkMemory()

void Arcane::ItemGroupImpl::shrinkMemory ( )

Limits the maximum memory used by the group.

If the group is a calculated group, it is invalidated and all its allocated memory is released.

If the group is a user-created group (i.e., persistent), it ensures that the consumed memory is minimal. Normally, Arcane allocates a few more elements than necessary to avoid frequent reallocations.

Integer Arcane::ItemGroupImpl::size ( ) const

Number of entities in the group.
