Detailed Description

template<typename T>
class b2TypedIntrusiveListNode< T >

b2TypedIntrusiveListNode which supports inserting an object into a single doubly linked list. For objects that need to be inserted in multiple doubly linked lists, use b2IntrusiveListNode.

For example:

class IntegerItem : public b2TypedIntrusiveListNode<IntegerItem> { public: IntegerItem(int32 value) : m_value(value) { } ~IntegerItem() { } int32 GetValue() const { return m_value; } private: int32 m_value; };

int main(int argc, const char <em>arvg[]) { b2TypedIntrusiveListNode<IntegerItem> list; IntegerItem a(1); IntegerItem b(2); IntegerItem c(3); list.InsertBefore(&a); list.InsertBefore(&b); list.InsertBefore(&c); for (IntegerItem item = list.GetNext(); item != list.GetTerminator(); item = item->GetNext()) { printf("%d\n", item->GetValue()); } }

Member Function Documentation

template<typename T>

T* b2TypedIntrusiveListNode< T >::GetNext ( ) const

inline

Get the next object in the list. Check against GetTerminator() before deferencing the object.

template<typename T>

T* b2TypedIntrusiveListNode< T >::GetPrevious ( ) const

inline

Get the previous object in the list. Check against GetTerminator() before deferencing the object.

template<typename T>

T* b2TypedIntrusiveListNode< T >::GetTerminator ( ) const

inline

Get the terminator of the list. This should not be dereferenced as it is a pointer to b2TypedIntrusiveListNode<T> not T.
