RequestFormData

<p>
	The {@link oajr.RequestFormData} object is the API for accessing the HTTP request body as form data.
	It can be accessed by passing it as a parameter on your REST Java method:
</p>
<p class='bpcode w800'>
	<ja>@RestMethod</ja>(...)
	<jk>public</jk> Object myMethod(RequestFormData query) {...}			
</p>
<h5 class='figure'>Example:</h5>
<p class='bpcode w800'>
	<ja>@RestMethod</ja>(...)
	<jk>public</jk> Object myMethod(RequestFormData formData) {

		<jc>// Get query parameters converted to various types.</jc>
		<jk>int</jk> p1 = formData.get(<js>"p1"</js>, 0, <jk>int</jk>.<jk>class</jk>);
		String p2 = formData.get(<js>"p2"</js>, String.<jk>class</jk>);
		UUID p3 = formData.get(<js>"p3"</js>, UUID.<jk>class</jk>);
	 }			
</p>
<p>
	Note that this object does NOT take GET parameters into account and only returns values found in the body of the request.
</p>
