Move‐insert a source range, shifting subsequent elements.

== Synopsis

Declared in `<bslalg_arrayprimitives.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
template<class TARGET_TYPE>
static
void
moveInsert(
    TARGET_TYPE* toBegin,
    TARGET_TYPE* toEnd,
    TARGET_TYPE** fromEndPtr,
    TARGET_TYPE* fromBegin,
    TARGET_TYPE* fromEnd,
    xref:BloombergLP/bslalg/ArrayPrimitives/size_type.adoc[size_type] numElements,
    xref:BloombergLP/bslma/Allocator.adoc[bslma::Allocator]* allocator);
----

== Description

Move the elements of the (template parameter) `TARGET_TYPE` in the array starting at the specified `toBegin` address and ending immediately before the specified `toEnd` address by the specified `numElements` positions towards larger addresses, and fill the `numElements` at the `toBegin` address by moving the elements from the array starting at the specified `fromBegin` and ending immediately before the specified `fromEnd` address. Keep the iterator at the specified `fromEndPtr` address pointing to the end of the range as the elements from `[ fromBegin, fromEnd )]` are moved from source to destination. The behavior is undefined unless the destination array contains `numElements` uninitialized elements after `toEnd`, `numElements` is the distance from `fromBegin` to `fromEnd`, and the input and destination arrays do not overlap. If a copy constructor or assignment operator for `TARGET_TYPE` throws an exception, then any elements created after `toEnd` are destroyed, the elements in the ranges `[ toBegin, toEnd)]` and `[ fromBegin, *fromEndPtr )]` will have unspecified, but valid, values, and the elements in `[ *fromEndPtr, fromEnd )]` will be destroyed.

== Parameters
