ns3::AttributeValue, ns3::AttributeAccessor and ns3::AttributeChecker declarations.
Anchor the ns-3 type and attribute system.
AttributeAccessor implementation for ObjectPtrContainerValue.
Container for a set of ns3::Object pointers.
Smart pointer class similar to boost::intrusive_ptr.
#define NS_ASSERT(condition)
At runtime, in debugging builds, if this condition is not true, the program prints the source file,...
