template<class X, class Priority = double, class STATICCOMPARER = StdComparer<X>, class INDEX = int>
class ogdf::DeletingTop10Heap< X, Priority, STATICCOMPARER, INDEX >
A variant of Top10Heap which deletes the elements that get rejected from the heap.
The datastructure of course requires the stored data-elements to be pointers (in order to be deletable when rejected). Hence the template parameter only specifies the data-type, without stating axplicitly that we considere pointers to the structure.
The datastructure also allows for non-duplicate insertions, i.e., a new element can be rejected if it is already in the heap. Note that only the compare function has to work

template<class X , class Priority = double, class STATICCOMPARER = StdComparer<X>, class INDEX = int>
Inserts the element x
into the heap with priority p
and deletes the element with smallest priority if the heap is full.
Like the Top10Heap, this function pushes the element x
onto the heap with priority p
, and extracts the element with smallest priority if the heap was already full. In contrast to the Top10Heap, this element which leaves the heap (or x
itself if its priority was below all the priorities in the heap) gets deleted, i.e., removed from memory.

Analogous to pushandDelete(), but furthermore rejects (and deletes) an element if an equal element is already in the heap.
This function takes linear time in the worst case, and uses the compare
function of the specified COMP template paremeter class, which can be any function returning true
if two objects should be considered equal, and false
otherwise.
