Proctor granting locked, direct access to the underlying `bsl::deque`.

== Synopsis

Declared in `<bdlcc_deque.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
class Proctor;
----

== Description

This class defines a proctor type that provides direct access to the underlying `bsl::deque` contained in a `Deque`. Creation of a `Proctor` object locks the mutex of the `Deque`, and destruction unlocks it.

| Name| Description
| xref:BloombergLP/bdlcc/Deque/Proctor/2constructor.adoc[`Proctor`]         [.small]#[constructor]#
| Create a `Proctor` for the optionally specified `container`.
| xref:BloombergLP/bdlcc/Deque/Proctor/2destructor.adoc[`~Proctor`] [.small]#[destructor]#
| Destroy this proctor and unlock its associated `Deque`.
| xref:BloombergLP/bdlcc/Deque/Proctor/isNull.adoc[`isNull`] 
| Return `true` if this object is not associated with a `Deque` object.
| xref:BloombergLP/bdlcc/Deque/Proctor/load.adoc[`load`] 
| Attach this proctor to the specified `container`.
| xref:BloombergLP/bdlcc/Deque/Proctor/operator_star.adoc[`operator*`] 
| Return a reference to the `bsl::deque` managed by this `Proctor` object. The behavior is undefined if this `Proctor` has been released.
| xref:BloombergLP/bdlcc/Deque/Proctor/operator_ptr.adoc[`operator‐>`] 
| Return a pointer to the `bsl::deque` contained in the `Deque` managed by this `Proctor` object'. The behavior is undefined if this `Proctor` has been released.
| xref:BloombergLP/bdlcc/Deque/Proctor/operator_subs.adoc[`operator[]`] 
| Return a modifiable reference to the element at `position`.
| xref:BloombergLP/bdlcc/Deque/Proctor/release.adoc[`release`] 
| Release this proctor without destroying it. Afterward the destructor will have no effect. This may be called multiple times; only the first call has any effect.
