Other Useful Methods

<p>
	The {@link oajrc.RestClientBuilder#rootUrl(Object)} method can be used to specify a 
	root URL on all requests so that you don't have to use absolute paths on individual calls.
</p>
<p class='bpcode w800'>
	<jc>// Create a rest client with a root URL</jc>
	RestClient rc = RestClient.<jsm>create</jsm>().rootUrl(<js>"http://localhost:9080/foobar"</js>).build();
	String r = rc.doGet(<js>"/baz"</js>).getResponseAsString();  <jc>// Gets "http://localhost:9080/foobar/baz"</jc>
</p>
<p>
	The {@link oajrc.RestClientBuilder#set(String,Object)} method can be used to 
	set serializer and parser properties.
	For example, if you're parsing a response into POJOs and you want to ignore fields that aren't on the
	POJOs, you can use the {@link oaj.BeanContext#BEAN_ignoreUnknownBeanProperties} property.
</p>
<p class='bpcode w800'>
	<jc>// Create a rest client that ignores unknown fields in the response</jc>
	RestClient rc = RestClient.<jsm>create</jsm>()
		.set(<jsf>BEAN_ignoreUnknownBeanProperties</jsf>, <jk>true</jk>)
		<jc>// or .ignoreUnknownBeanProperties(true)</jc>
		.build();
	MyPojo myPojo = rc.doGet(<jsf>URL</jsf>).getResponse(MyPojo.<jk>class</jk>);
</p>
<p>
	The {@link oajrc.RestCall#retryable(int,long,RetryOn)} method can be used to 
	automatically retry requests on failures.
	This can be particularly useful if you're attempting to connect to a REST resource that may be in the 
	process of still initializing.
</p>
<p class='bpcode w800'>
	<jc>// Create a rest call that retries every 10 seconds for up to 30 minutes as long as a connection fails
	// or a 400+ is received.</jc>
	restClient.doGet(<jsf>URL</jsf>)
		.retryable(180, 10000, RetryOn.<jsf>DEFAULT</jsf>)
		.run();
</p>
