	URI targetUri = rangeQueryBuilder.withQuery("irate(received_api_call_total[60s])")
		                 .withStartEpochTime(System.currentTimeMillis() / 1000 - 60*10)
		                 .withEndEpochTime(System.currentTimeMillis() / 1000)
		                 .withStepTime("60s")
		                 .build();
``` 
### InstantQuery
```
	InstantQueryBuilder iqb = QueryBuilderType.InstantQuery.newInstance(TARGET_SERVER);
	URI targetUri = iqb.withQuery("irate(received_api_call_total[60s])").build();
``` 
### LabelQuery
```
	LabelMetaQueryBuilder lmqb = QueryBuilderType.LabelMetadaQuery.newInstance(TARGET_SERVER);
	URI targetUri = lmqb.withLabel("pod").build();
```
