Functions

Public

Name Remarks Include Path Unreal Specifiers

ConstIteratorType begin ()

 STL IteratorType model compliance methods. Containers/Deque.h  

IteratorType begin ()

   Containers/Deque.h  

ElementType & EmplaceFirst ( ArgsType&&... Args
)

 Constructs an element in place using the parameter arguments and adds it at the front of the queue. Containers/Deque.h  

ElementType & EmplaceLast ( ArgsType&&... Args
)

 Constructs an element in place using the parameter arguments and adds it at the back of the queue. Containers/Deque.h  

void Empty()

 Empties the queue effectively destroying all contained elements and releases any acquired storage. Containers/Deque.h  

IteratorType end ()

   Containers/Deque.h  

ConstIteratorType end ()

   Containers/Deque.h  

ElementType & First ()

   Containers/Deque.h  

const ElementType & First ()

   Containers/Deque.h  

SIZE_T GetAllocatedSize ()

 Helper function to return the amount of memory allocated by this container. Containers/Deque.h  

bool IsEmpty()

   Containers/Deque.h  

ElementType & Last ()

   Containers/Deque.h  

const ElementType & Last ()

   Containers/Deque.h  

SizeType Max()

   Containers/Deque.h  

SizeType Num()

   Containers/Deque.h  

void PopFirst()

 Removes the element at the front of the queue. This method requires a non-empty queue. Containers/Deque.h  

void PopLast()

 Removes the element at the back of the queue. This method requires a non-empty queue. Containers/Deque.h  

void PushFirst ( ElementType&& Element
)

   Containers/Deque.h  

void PushFirst ( const ElementType& Element
)

 Adds the parameter element at the front of the queue. Containers/Deque.h  

void PushLast ( ElementType&& Element
)

   Containers/Deque.h  

void PushLast ( const ElementType& Element
)

 Adds the parameter element at the back of the queue. Containers/Deque.h  

void Reserve ( SizeType InCount
)

 Reserves storage for the parameter element count. Containers/Deque.h  

void Reset()

 Destroys all contained elements but doesn't release the container's storage. Containers/Deque.h  

bool TryPopFirst ( ElementType& OutValue
)

 Removes the element at the front of the queue if existent after copying it to the parameter out value. Containers/Deque.h  

bool TryPopLast ( ElementType& OutValue
)

 Removes the element at the back of the queue if existent after copying it to the parameter out value. Containers/Deque.h
