:relfileprefix: ../../../
:mrdocs:

Create a queue from the leading `numElements` of `srcArray`.

== Synopsis

Declared in `<bdlc_queue.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
Queue(
    T const* srcArray,
    int numElements,
    xref:BloombergLP/bslma/Allocator.adoc[bslma::Allocator]* basicAllocator = 0);
----

== Description

Create an in‐place queue initialized with the specified `numElements` leading values from the specified `srcArray`. Optionally specify the `basicAllocator` used to supply memory. If `basicAllocator` is 0, the currently installed default allocator is used. The behavior is undefined unless `0 <= numElements`. Note that `srcArray` must refer to sufficient memory to hold `numElements` values.
