void AllocatedArray< T >::GrowDiscard | ( | size_type | _size | ) |
| inline

Grows the array to the specified size, discarding old data.

Similar to ResizeDiscard(), but will never shrink the array to avoid expensive heap operations.

template<class T>

void AllocatedArray< T >::GrowPreserve | ( | size_type | _size,
|  | size_type | preserve

Resizes the array, discarding old data.

template<class T>

void AllocatedArray< T >::SetSize | ( | size_type | _size | ) |
| inline

Declare that the buffer has the specified size.

Must not be larger than the current size. Excess elements are not used (but they are still allocated).

Definition at line 214 of file AllocatedArray.hxx.

template<class T>

constexpr size_type AllocatedArray< T >::size | ( |  | ) | const
