Hi,
The following message was posted some time ago, but it seems quite
surprising to me!... =)
Does it mean that I should avoid creating and erasing FieldContainers
repeatedly? If somehow, my algorithms end up creating and erasing FC's (let
say.. every frame), am I going on memory leak?
Is this the expected behaviour for version 1.8 and 2.0 of OpenSG?
Is there another way to overcome this issue? Like cleaning the changelist
once in a while?
Its not clear to me, why the FieldContainerFactory should be aware of every
FieldContainer instance of the program. Could somebody clarify that to me?
=)
Thanks in advance,
Olavo.

each of the create calls appends an element to a std::vector in
FieldContainerFactory. This is used for various things and allows one to
retrieve a container when only its id is known. In cases where huge
numbers of objects are created this can result in a significant increase
in memory use. AFAIK there have been only very few problems with this
(in real world applications), but it would be possible to choose another
memory/performance tradeoff inside the factory.
It is generally better to reuse objects where possible, especially since
object creation is not really a lightweight operation.
Hope it helps,
Carsten
