| Constructors
| xref:BloombergLP/ball/ManagedAttribute/operator_assign.adoc[`operator=`] 
| Assign to this object the value of the specified `rhs` object, and return a non‐`const` reference to this object.
| xref:BloombergLP/ball/ManagedAttribute/attribute.adoc[`attribute`] 
| Return a `const` reference to the attribute of this object.
| xref:BloombergLP/ball/ManagedAttribute/get_allocator.adoc[`get_allocator`] 
| Return the allocator used by this object to supply memory. Note that if no allocator was supplied at construction the default allocator in effect at construction is used.
| xref:BloombergLP/ball/ManagedAttribute/key.adoc[`key`] 
| Return a `const` reference to the attribute name of this object.
| xref:BloombergLP/ball/ManagedAttribute/name.adoc[`name`] 
| Return the attribute name of this object. Note that this accessor should not be used to get the attribute name if the name string contains embedded zeros.
| xref:BloombergLP/ball/ManagedAttribute/print.adoc[`print`] 
| Format this object to the specified output `stream` at the (absolute value of) the optionally specified indentation `level` and return a reference to `stream`. If `level` is specified, optionally specify `spacesPerLevel`, the number of spaces per indentation level for this and all of its nested objects. If `level` is negative, suppress indentation of the first line. If `spacesPerLevel` is negative, format the entire output on one line, suppressing all but the initial indentation (as governed by `level`). If `stream` is not valid on entry, this operation has no effect.
| xref:BloombergLP/ball/ManagedAttribute/setName.adoc[`setName`] 
| Set the attribute name of this object to the specified `name`.
| xref:BloombergLP/ball/ManagedAttribute/setValue-059.adoc[`setValue`] 
| `setValue` overloads
| xref:BloombergLP/ball/ManagedAttribute/value.adoc[`value`] 
| Return a `const` reference to the attribute value of this object.
| xref:BloombergLP/ball/ManagedAttribute/2conversion.adoc[`operator BloombergLP::bslmf::NestedTraitDeclaration<ManagedAttribute, UsesBslmaAllocator>`] 
| Declare that this type uses a `bslma` allocator.

| Name| Description
| xref:BloombergLP/ball/ManagedAttribute/hash.adoc[`hash`] 
| Return a hash value calculated from the specified `attribute` using the specified `size` as the number of slots. The hash value is guaranteed to be in the range `[0 .. size ‐ 1]`. The behavior is undefined unless `0 < size`.

== Friends

[cols="1,4"]

| Name| Description
| `xref:BloombergLP/ball/operator_lshift-0a7.adoc[BloombergLP::ball::operator<<]`
| Write the value of the specified `attribute` to the specified `output` stream. Return the specified `output` stream.
| `xref:BloombergLP/ball/operator_not_eq-00.adoc[BloombergLP::ball::operator!=]`
| Return `true` if the specified `lhs` and `rhs` objects do not have the same value, and `false` otherwise. Two `ManagedAttribute` objects do not have the same value if any of their respective names, attribute value types, or attribute values differ.
| `xref:BloombergLP/ball/operator_eq-008.adoc[BloombergLP::ball::operator==]`
| Return `true` if the specified `lhs` and `rhs` objects have the same value, and `false` otherwise. Two `ManagedAttribute` objects have the same value if they have the same name, same attribute value type, and the same attribute value.

== Non-Member Functions

[cols="1,4"]

| Name| Description
| xref:BloombergLP/ball/operator_not_eq-0e.adoc[`operator!=`]
| Return `true` if the specified `lhs` and `rhs` objects do not have the same value, and `false` otherwise.
| xref:BloombergLP/ball/operator_eq-08e7.adoc[`operator==`]
