#define forAll(list, i)
Loop across all elements in list.
Definition: UList.H:434
intWM_LABEL_SIZE_t label
A label is an int32_t or int64_t as specified by the pre-processor macro WM_LABEL_SIZE.
Definition: label.H:59
Type & operator[](const label)
Return element of UList.
Definition: UListI.H:167
SortableListEFA(const List< Type > &)
Construct from List, sorting the elements. Starts with indices set.
A list that is sorted upon construction or when explicitly requested with the sort() method...
iterator end()
Return an iterator to end traversing the UList.
Definition: UListI.H:237
static bool less(const vector &x, const vector &y)
To compare normals.
const labelList & indices() const
Return the list of sorted indices. Updated every sort.
void operator=(const SortableListEFA< Type > &)
Functions used by OpenFOAM that are specific to POSIX compliant operating systems and need to be repl...
void sort(UList< T > &)
Definition: UList.C:115
iterator begin()
Return an iterator to begin traversing the UList.
Definition: UListI.H:216
Less function class used by the sort function.
void setSize(const label)
Size the list. If grow can cause undefined indices (until next sort)
void operator=(const UList< T > &)
Assignment to UList operator. Takes linear time.
Definition: List.C:376
void setSize(const label)
Reset size of List.
Definition: List.C:281
void partialSort(int M, int start)
Partial sort the list (if changed after construction time)
void stableSort()
Sort the list (if changed after construction time)
void stableSort(UList< T > &)
Definition: UList.C:129
label size() const
Return the number of elements in the UList.
Definition: ListI.H:171
void transfer(List< T > &)
Transfer the contents of the argument List into this list.
Definition: List.C:342
#define M(I)
void sort()
Sort the list (if changed after construction time)
