Member Function Documentation

Contains_Debug()

bool FSlateInvalidationWidgetPreHeap::Contains_Debug ( const FSlateInvalidationWidgetIndex  WidgetIndex ) const

inline

Does it contains the widget index.

ForEachIndexes()

template<typename Predicate >

void FSlateInvalidationWidgetPreHeap::ForEachIndexes ( Predicate  Pred )

inline

Iterate over each element in the list in any order.

GetRaw()

const FElementContainer & FSlateInvalidationWidgetPreHeap::GetRaw ( ) const

inline

Returns the raw list.

HeapPeek()

FSlateInvalidationWidgetIndex FSlateInvalidationWidgetPreHeap::HeapPeek ( ) const

inline

Returns the biggest WidgetIndex from the list.

HeapPeekElement()

const FElement & FSlateInvalidationWidgetPreHeap::HeapPeekElement ( ) const

inline

Returns the biggest WidgetIndex from the list.

HeapPop()

FSlateInvalidationWidgetIndex FSlateInvalidationWidgetPreHeap::HeapPop ( )

inline

Returns and removes the biggest WidgetIndex from the list.

HeapPopDiscard()

void FSlateInvalidationWidgetPreHeap::HeapPopDiscard ( )

inline

Removes the biggest WidgetIndex from the list.

HeapPushUnique()

void FSlateInvalidationWidgetPreHeap::HeapPushUnique ( FSlateInvalidationWidgetList::InvalidationWidgetType &  InvalidationWidget )

inline

Insert into the list at the proper order (see binary heap) only if it's not already contains by the list.

IsValidHeap_Debug()

bool FSlateInvalidationWidgetPreHeap::IsValidHeap_Debug ( )

inline

@retuns true if the heap is heapified.

Num()

int32 FSlateInvalidationWidgetPreHeap::Num ( ) const

inline

Returns the number of elements in the list.

RemoveRange()

int32 FSlateInvalidationWidgetPreHeap::RemoveRange ( const FSlateInvalidationWidgetList::FIndexRange &  Range )

inline

Remove range

Reset()

void FSlateInvalidationWidgetPreHeap::Reset ( bool  bResetContained )

inline

Empties the list, but doesn't change memory allocations.
