pushBack(xref:BloombergLP/bslmf/MovableRef.adoc[bslmf::MovableRef<JsonObject>] object);
----

== Description

Append to the end of this `Json` object's array the specified move‐insertable `object` and return a non‐`const` reference to this object. `object` is left in a valid but unspecified state. If `isNull()`, then the type is changed to array. If an exception is thrown, `*this` is unaffected. Throw `bsl::length_error` if `size() == maxSize()`. The behavior is undefined unless `isArray()` or `isNull()`.

== Return Value

a reference providing modifiable access to this object

== Parameters
