class Geo GeoArray

template<typename>
class Geo::GeoArray

Basic templated dynamic array class.

This contains roughly the same functionality as the std::vector class, but gives more control over the internal memory it uses.

Note

The type that is used to instantiate the array template must support an assignment operator.

If the new size is larger than the current size than new elements of value 'elem' are added. If the new size is smaller than the current size then the elements closest to the end of the array are deleted until the current size is equal to the new size. The memory for the array gets reallocated if the new size is larger than the current capacity. In the reallocation it is tried to grow the capacity by 50 %, or if the new size is larger than that then the new capacity is set to the new size.

Parameters
[in] newSize

The new size of the array.

[in] elem

Value for elements that get added if newSize is larger than the current size.

Return Value
false

If newSize is smaller than zero, or if additional memory could not be allocated.


bool Geo::GeoArray< T >::SetCapacity


public: bool SetCapacity
(
    s32 newCapacity
)


Change the array's capacity, reallocating memory if the new capacity is different to the current capacity.

Parameters
[in] newCapacity

The new capacity of the array. May not be less than the current size.

Return Value
false

If newCapacity is smaller than the current size, or if newCapacity is larger than MAX_CAPACITY, or if additional memory could not be allocated.


void Geo::GeoArray< T >::Swap


public: void Swap
(
    GeoArray & other
)


Swap the contents of two arrays.

This function does not re-allocate any memory. If A = {0, 1, 2} and B = {3, 4} then A.Swap(B) results in A = {3, 4} and B = {0, 1, 2}.

Parameters
[in] other

Other array that the contents of this array will be swapped with.
