:relfileprefix: ../../../
: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 TARGET_TYPE>
static
void
moveConstruct(
    TARGET_TYPE* toBegin,
    TARGET_TYPE* fromBegin,
    TARGET_TYPE* fromEnd,
    xref:BloombergLP/bslma/Allocator.adoc[bslma::Allocator]* allocator);
----

== Description

Move the elements of the (template parameter) `TARGET_TYPE` starting at the specified `fromBegin` address and ending immediately before the specified `fromEnd` address into the uninitialized array of `TARGET_TYPE` beginning at the specified `toBegin` address, 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"]
