:mrdocs:

Move‐construct elements from a range into an uninitialized array.

== Synopsis

Declared in `<bslalg_arrayprimitives.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
template<class ALLOCATOR>
static
void
moveConstruct(
    bsl::allocator_traits<ALLOCATOR>::pointer toBegin,
    bsl::allocator_traits<ALLOCATOR>::pointer fromBegin,
    bsl::allocator_traits<ALLOCATOR>::pointer fromEnd,
    ALLOCATOR allocator);
----

== Description

Move the elements of type `allocator_traits<ALLOCATOR>::value_type` in the range beginning at the specified `fromBegin` location and ending immediately before the specified `fromEnd` location into the uninitialized array beginning at the specified `toBegin` location, using the specified `allocator` to supply memory (if required). The elements in the input array are left in a valid but unspecified state. If a constructor throws an exception during this operation, the output array is left in an uninitialized state. The behavior is undefined unless `toBegin` refers to space sufficient to hold `fromEnd ‐ fromBegin` elements.

== Parameters

[cols="1,4"]
|===
| Name| Description
| *toBegin*
| beginning of the uninitialized destination range
| *fromBegin*
| beginning of the source range
| *fromEnd*
| end of the source range (one past the last element)
| *allocator*
| allocator used to supply memory if required
