HTTP Part Parsers

<p>
	There is a separate set of parsers for parsing HTTP parts (query, form-data, headers, path variables, and plain-text request bodies).
	The distinction is that these are designed to parse directly from strings based on Open-API schema information.
</p>
<p class='bpcode w800'>
	<jc>// Schema information about our part.</jc>
	HttpPartSchema schema = HttpPartSchema
		.<jsm>create</jsm>(<js>"array"</js>)
		.collectionFormat(<js>"pipes"</js>)
		.items(
			HttpPartSchema
				.<jsm>create</jsm>(<js>"array"</js>)
				.collectionFormat(<js>"csv"</js>)
				.items(
					HttpPartSchema.<jsm>create</jsm>(<js>"integer"</js>,<js>"int64"</js>)
				)
		)
		.build();

	<jc>// Our input to parse.</jc>
	String input = <js>"1,2,3|4,5,6|7,8,9"</js>;

	<jc>// Produces "[[1,2,3],[4,5,6],[7,8,9]]</jc>
	<jk>long</jk>[][] value = OpenApiParser.<jsf>DEFAULT</jsf>.parse(HttpPartType.<jsf>HEADER</jsf>, schema, input, <jk>long</jk>[][].<jk>class</jk>);
</p>
<p>
	The class hierarchy for the part serializers are:
</p>

<ul class='javatree'>
	<li class='jic'>{@link oaj.httppart.HttpPartParser}
	<ul>
		<li class='jc'>{@link oaj.httppart.SimplePartParser} - Parses directly from strings.
		<li class='jc'>{@link oaj.uon.UonParser} - Parses from UON notation.
		<ul>
			<li class='jc'>{@link oaj.oapi.OpenApiParser} - Parses using Open-API schema rules.
		</ul>
	</ul>
</ul>
