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

Class to represent the properties of an attribute in an XML element tag. Note that this class is not value semantic and does not own any of its pointer values. The owner of the arguments used to set the value of a `ElementAttribute` is responsible for ensuring that the values remain valid or else must document the conditions that will make the values invalid. Some facets are computed the first time that they are needed. To avoid extra processing, the caller may supply otherwise‐computed facets at construction or by calling `reset`. Facets provided by the caller are not checked to ensure that they are consistent with one another.

| xref:BloombergLP/balxml/ElementAttribute/2constructor-0d.adoc[`ElementAttribute`]         [.small]#[constructor]#
| Constructors
| xref:BloombergLP/balxml/ElementAttribute/flags.adoc[`flags`] 
| Return the value of `flags` specified at the last call to `reset` or the constructor, if non‐zero, or zero otherwise. Pre‐defined flags are enumerated in the class definition.
| xref:BloombergLP/balxml/ElementAttribute/isNull.adoc[`isNull`] 
| Return true if this object is null. More precisely, return true if `qualifiedName()` returns 0. A default‐constructed object will be null, as will an object that was reset with no arguments.
| xref:BloombergLP/balxml/ElementAttribute/localName.adoc[`localName`] 
| Return the value of `localName` specified at the last call to `reset` or the constructor, if non‐zero, else return the local part of the qualified name. More precisely, return the portion of `qualifiedName()` after the colon, if any, or the entire `qualifiedName()` if there is no colon.
| xref:BloombergLP/balxml/ElementAttribute/namespaceId.adoc[`namespaceId`] 
| Return the value of `localName` specified at the last call to `reset` or the constructor, if not `INT_MIN`, else return the ID returned by the prefix stack for the current value of `prefix()`. Return ‐1 if `prefix()` is an empty string, `prefixStack()` is zero, or `prefix()` is not active in the prefix stack. Note that, as per the XML namespace standard, an empty prefix does _NOT_ refer to the default namespace, but rather refers to _NO_ namespace.
| xref:BloombergLP/balxml/ElementAttribute/namespaceUri.adoc[`namespaceUri`] 
| Return the value of `namespaceUri` specified at the last call to `reset` or the constructor, if non‐zero, else return the URI returned by the prefix stack for the current value of `prefix()`. Return an empty string if `prefix()` is an empty string, `prefixStack()` is zero, or `prefix()` is not active in the prefix stack. Note that, as per the XML namespace standard, an empty prefix does _NOT_ refer to the default namespace, but rather refers to _NO_ namespace.
| xref:BloombergLP/balxml/ElementAttribute/prefix.adoc[`prefix`] 
| Return the value of `prefix` specified at the last call to `reset` or the constructor, if non‐zero, else return a copy of the prefix portion of the qualified name. More precisely, return a copy of the portion of `qualifiedName()` up to, but not including, the colon. Return an empty string if the qualified name has no colon or if `prefixStack()` returns zero.
| xref:BloombergLP/balxml/ElementAttribute/prefixStack.adoc[`prefixStack`] 
| Return the value of `prefixStack` specified at the last call to `reset` or the constructor or 0 if no prefix stack was specified.
| xref:BloombergLP/balxml/ElementAttribute/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. If `stream` is not valid on entry, this operation has no effect. Facet values that have not yet been computed are represented by "<null>" in the resulting stream.
| xref:BloombergLP/balxml/ElementAttribute/qualifiedName.adoc[`qualifiedName`] 
| Return the value of `qualifiedName` specified at the last call to `reset` or the constructor or 0 if no qualified name was specified.
| xref:BloombergLP/balxml/ElementAttribute/reset-0b.adoc[`reset`] 
| `reset` overloads
| xref:BloombergLP/balxml/ElementAttribute/value.adoc[`value`] 
| Return the value of `value` specified at the last call to `reset` or the constructor or 0 if no value was specified.
| xref:BloombergLP/balxml/ElementAttribute/2conversion.adoc[`operator BloombergLP::bslmf::NestedTraitDeclaration<ElementAttribute, is_trivially_copyable>`] 
| `ElementAttribute` is trivially copyable.
