| Name| Description
| xref:BloombergLP/bdlb/ArrayUtil/begin.adoc[`begin`] 
| Return an iterator pointing to the first element of the specified `array` of template parameter `LENGTH` elements of template parameter `TYPE`.
| xref:BloombergLP/bdlb/ArrayUtil/end.adoc[`end`] 
| Return the past‐the‐end iterator for the specified `array` of template parameter `LENGTH` elements of template parameter `TYPE`.
| xref:BloombergLP/bdlb/ArrayUtil/length.adoc[`length`] 
| Return the number of elements in the specified `array` of template parameter `LENGTH` elements of template parameter `TYPE`. This method is synonymous with the `size` method.
| xref:BloombergLP/bdlb/ArrayUtil/rbegin.adoc[`rbegin`] 
| Return a reverse iterator pointing to the last element of the specified `array` of template parameter `LENGTH` elements of template parameter `TYPE`.
| xref:BloombergLP/bdlb/ArrayUtil/rend.adoc[`rend`] 
| Return the past‐the‐end reverse iterator for the specified `array` of template parameter `LENGTH` elements of template parameter `TYPE`.
| xref:BloombergLP/bdlb/ArrayUtil/size.adoc[`size`] 
| Return the number of elements in the specified `array` of template parameter `LENGTH` elements of template parameter `TYPE`. This method is synonymous with the `length` method.
| xref:BloombergLP/bdlb/ArrayUtil/sizer.adoc[`sizer`] 
| Return a reference to an array of `char`s with the same number of elements as the specified `array` of template parameter `LENGTH` elements of template parameter `TYPE`. This function is _not_ implemented and can only be used in a non‐evaluated context. The function is used together with `sizeof` to obtain a constant expression with the `LENGTH` of the `array`. See `BDLB_ARRAYUTIL_SIZE` and `BDLB_ARRAYUTIL_LENGTH`.
