		An optimized string type for unique names.
	</brief_description>
	<description>
		[StringName]s are immutable strings designed for general-purpose representation of unique names (also called "string interning"). [StringName] ensures that only one instance of a given name exists (so two [StringName]s with the same value are the same object). Comparing them is much faster than with regular [String]s, because only the pointers are compared, not the whole strings.
		You will usually just pass a [String] to methods expecting a [StringName] and it will be automatically converted, but you may occasionally want to construct a [StringName] ahead of time with [StringName] or, in GDScript, the literal syntax [code]&amp;"example"[/code].
		See also [NodePath], which is a similar concept specifically designed to store pre-parsed node paths.
		Some string methods have corresponding variations. Variations suffixed with [code]n[/code] ([method countn], [method findn], [method replacen], etc.) are [b]case-insensitive[/b] (they make no distinction between uppercase and lowercase letters). Method variations prefixed with [code]r[/code] ([method rfind], [method rsplit], etc.) are reversed, and start from the end of the string, instead of the beginning.
		[b]Note:[/b] In a boolean context, a [StringName] will evaluate to [code]false[/code] if it is empty ([code]StringName("")[/code]). Otherwise, a [StringName] will always evaluate to [code]true[/code].

			</description>
		</method>
		<method name="findn" qualifiers="const">
			<return type="int" />
			<param index="0" name="what" type="String" />
			<param index="1" name="from" type="int" default="0" />
			<description>
				Returns the index of the [b]first[/b] [b]case-insensitive[/b] occurrence of [param what] in this string, or [code]-1[/code] if there are none. The starting search index can be specified with [param from], continuing to the end of the string.

		</method>
		<method name="format" qualifiers="const">
			<return type="String" />
			<param index="0" name="values" type="Variant" />
			<param index="1" name="placeholder" type="String" default="&quot;{_}&quot;" />
			<description>
				Formats the string by replacing all occurrences of [param placeholder] with the elements of [param values].
				[param values] can be a [Dictionary] or an [Array]. Any underscores in [param placeholder] will be replaced with the corresponding keys in advance. Array elements use their index as keys.
				[codeblock]
				# Prints "Waiting for Godot is a play by Samuel Beckett, and Godot Engine is named after it."
				var use_array_values = "Waiting for {0} is a play by {1}, and {0} Engine is named after it."
				print(use_array_values.format(["Godot", "Samuel Beckett"]))

				# Prints "User 42 is Godot."
				print("User {id} is {name}.".format({"id": 42, "name": "Godot"}))
				[/codeblock]
				Some additional handling is performed when [param values] is an [Array]. If [param placeholder] does not contain an underscore, the elements of the [param values] array will be used to replace one occurrence of the placeholder in order; If an element of [param values] is another 2-element array, it'll be interpreted as a key-value pair.
				[codeblock]
				# Prints "User 42 is Godot."
				print("User {} is {}.".format([42, "Godot"], "{}"))
				print("User {id} is {name}.".format([["id", 42], ["name", "Godot"]]))

		<method name="naturalnocasecmp_to" qualifiers="const">
			<return type="int" />
			<param index="0" name="to" type="String" />
			<description>
				Performs a [b]case-insensitive[/b], [i]natural order[/i] comparison to another string. Returns [code]-1[/code] if less than, [code]1[/code] if greater than, or [code]0[/code] if equal. "Less than" or "greater than" are determined by the [url=https://en.wikipedia.org/wiki/List_of_Unicode_characters]Unicode code points[/url] of each string, which roughly matches the alphabetical order. Internally, lowercase characters are converted to uppercase for the comparison.
				When used for sorting, natural order comparison orders sequences of numbers by the combined value of each digit as is often expected, instead of the single digit's value. A sorted sequence of numbered strings will be [code]["1", "2", "3", ...][/code], not [code]["1", "10", "2", "3", ...][/code].
				With different string lengths, returns [code]1[/code] if this string is longer than the [param to] string, or [code]-1[/code] if shorter. Note that the length of empty strings is [i]always[/i] [code]0[/code].
				To get a [bool] result from a string comparison, use the [code]==[/code] operator instead. See also [method nocasecmp_to] and [method casecmp_to].

				Splits the string using a [param delimiter] and returns an array of the substrings. If [param delimiter] is an empty string, each substring will be a single character. This method is the opposite of [method join].
				If [param allow_empty] is [code]false[/code], empty strings between adjacent delimiters are excluded from the array.
