Section Beans

<p>
	Config files can also be used to directly populate beans using 
	{@link oaj.config.Config#getSectionAsBean(String,Class,boolean)}.
</p>
<h5 class='figure'>Example:</h5>
<p class='bpcode w800'>
	<jc>// Example config file</jc>
	<cs>[MyAddress]</cs>
	<ck>street</ck> = <cv>123 Main Street</cv>
	<ck>city</ck> = <cv>Anywhere</cv>
	<ck>state</ck> = <cv>NY</cv>
	<ck>zip</ck> = <cv>12345</cv>
</p>
<p class='bpcode w800'>
	<jc>// Example bean</jc>
	<jk>public class</jk> Address {
		<jk>public</jk> String <jf>street</jf>, <jf>city</jf>;
		<jk>public</jk> StateEnum <jf>state</jf>;
		<jk>public int</jk> <jf>zip</jf>;
	}

	<jc>// Example usage</jc>
	Config c = Config.<jsm>create</jsm>(<js>"MyConfig.cfg"</js>).build();
	Address myAddress = c.getSectionAsBean(<js>"MyAddress"</js>, Address.<jk>class</jk>);
</p>
<p>
	Like maps, beans created this way are snapshot copies of the section at the time of the method call.
