Functions

  Type Name Description
Public function int32

Add ( T* Item
)

 Adds a new item to the end of the array, possibly reallocating the whole array to fit.
Public function Const TDereferencingIterator< const ElementType, typename InternalArrayType::RangedForConstIteratorType >

begin ()

  
Public function TDereferencingIterator< ElementType, typename InternalArrayType::RangedForIteratorType >

begin ()

 DO NOT USE DIRECTLY STL-like iterators to enable range-based for loop support.
Public function Const void Count bytes needed to serialize this array.
Public function Const TConstIterator Creates a const iterator for the contents of this array.
Public function TIterator Creates an iterator for the contents of this array.
Public function void

Empty ( int32 Slack
)

 Empties the array. It calls the destructors on held items.
Public function Const TDereferencingIterator< const ElementType, typename InternalArrayType::RangedForConstIteratorType >

end ()

  
Public function TDereferencingIterator< ElementType, typename InternalArrayType::RangedForIteratorType >

end ()

  
Public function Const SIZE_T Helper function to return the amount of memory allocated by this container
Public function Const const T **

GetData ()

 Helper function for returning a typed pointer to the first array entry.
Public function T **

GetData ()

 Helper function for returning a typed pointer to the first array entry.
Public function Static constexpr uint32 Helper function returning the size of the inner type.
Public function void

Insert ( T* Item,
int32 Index
)

 Inserts a given element into the array at given location.
Public function Const bool

IsEmpty ()

 Returns true if the array is empty and contains no elements.
Public function Const bool

IsValidIndex ( int32 Index
)

 Tests if index is valid, i.e. greater than zero and less than number of elements in array.
Public function ElementType &

Last ( int32 IndexFromTheEnd
)

 Returns n-th last element from the array.
Public function Const const ElementType &

Last ( int32 IndexFromTheEnd
)

 Returns n-th last element from the array.Const version.
Public function Const int32

Num ()

 Gets number of elements in array.
Public function void

RemoveAt ( int32 Index,
int32 Count,
bool bAllowShrinking
)

 Removes an element (or elements) at given location optionally shrinking the array.
Public function void

RemoveAtSwap ( int32 Index,
int32 Count,
bool bAllowShrinking
)

 Removes an element (or elements) at given location optionally shrinking the array.
Public function void

Reserve ( int32 Number
)

 Reserves memory such that the array can contain at least Number elements.
Public function void

Reset ( int32 NewSize
)

 Resets the array to the new given size. It calls the destructors on held items.
Public function void

Serialize ( FArchive& Ar,
UObject* Owner
)

 Special serialize function passing the owning UObject along as required by FUnytpedBulkData serialization.
Public function void

Shrink ()

 Shrinks the array's used memory to smallest possible to store elements currently in it.
Public function void

Swap ( int32 FirstIndexToSwap,
int32 SecondIndexToSwap
)

 Element-wise array element swap.This version is doing more sanity checks than SwapMemory.

Operators

  Type Name Description
Public function T &

operator[] ( int32 Index
)

 Bracket array access operator.
Public function Const const T &

operator[] ( int32 Index
)

 Bracket array access operator.Const version.
Public function TIndirectArray &

operator= ( const TIndirectArray& Other
)

 Assignment operators.
Public function TIndirectArray &
