Name	Brief	Example
Add	Adds one element to the end of the array	Examples
Array	Default constructor to create an empty array	Examples
GetAt	Provides access to an element in the array	Examples
GetSize	Provides access to the size of the array	Examples
InsertAt	Inserts one element at a specified index in the array.	Examples
IsOwner	Access to the ownership value of the array	Examples
RemoveAt	It removes the object at the supplied index from the array. If owner, the object will be destroyed.	Examples

SetAt	Adds a reference to the passed object newElement, at the indicated index nIndex.	Examples
SetAtGrow	Adds a reference to the passed object newElement, at the indicated index nIndex. Enlarges the array if needed.	Examples
SetSize	Updates array size to the requested size	Examples
