| Constructors
| xref:BloombergLP/bdld/DatumMapEntry/key.adoc[`key`] 
| Return the key for this entry.
| xref:BloombergLP/bdld/DatumMapEntry/print.adoc[`print`] 
| Write the value of this object to the specified output `stream` in a human‐readable format, and return a reference to the modifiable `stream`. Optionally specify an initial indentation `level`, whose absolute value is incremented recursively for nested objects. If `level` is specified, optionally specify `spacesPerLevel`, whose absolute value indicates 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. Note that this human‐readable format is not fully specified, and can change without notice.
| xref:BloombergLP/bdld/DatumMapEntry/setKey.adoc[`setKey`] 
| Set the key for this entry to the specified `key`.
| xref:BloombergLP/bdld/DatumMapEntry/setValue.adoc[`setValue`] 
| Set the value for this entry to the specified `value`.
| xref:BloombergLP/bdld/DatumMapEntry/value.adoc[`value`] 
| Return the value for this entry.
| xref:BloombergLP/bdld/DatumMapEntry/2conversion.adoc[`operator BloombergLP::bslmf::NestedTraitDeclaration<DatumMapEntry, HasPrintMethod>`]

| Name| Description
| xref:BloombergLP/bdld/operator_not_eq-0ae.adoc[`operator!=`]
| Return `true` if the specified `lhs` and `rhs` have different values, and `false` otherwise. Two `DatumMapEntry` objects have different values if either the keys or values are not equal.
| xref:BloombergLP/bdld/operator_eq-000.adoc[`operator==`]
| Return `true` if the specified `lhs` and `rhs` have the same value, and `false` otherwise. Two `DatumMapEntry` objects have the same value if their keys and values compare equal.
