Detailed Description

This corresponds to a entry within a group.

It indicates the condition at which a level-of-detail is switched in or out. This is actually an abstract base class for potentially any number of specific different kinds of switching conditions; presently, only a type is actually supported.

virtual EggSwitchCondition* EggSwitchCondition::make_copy (   )  const [pure virtual]
 

Implemented in EggSwitchConditionDistance.

Referenced by EggGroup::clear_collide_mask(), and force_init_type().

int ReferenceCount::ref (   )  const [inline, inherited]
 

Explicitly increments the reference count.

User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically.

This function is const, even though it changes the object, because generally fiddling with an object's reference count isn't considered part of fiddling with the object. An object might be const in other ways, but we still need to accurately count the number of references to it.

The return value is the new reference count.

virtual void EggSwitchCondition::transform (  const LMatrix4d &  mat  )  [pure virtual]
 

Implemented in EggSwitchConditionDistance.

Referenced by force_init_type().

int ReferenceCount::unref (   )  const [inline, inherited]
 

Explicitly decrements the reference count.

Note that the object will not be implicitly deleted by unref() simply because the reference count drops to zero. (Having a member function delete itself is problematic; plus, we don't have a virtual destructor anyway.) However, see the helper function unref_delete().
