org.springframework.xd.dirt.core.StreamDeploymentsPath
Builder object for paths under {@link Paths#STREAM_DEPLOYMENTS}. {@code StreamDeploymentsPath}can be used to take a full path and split it into its elements, for example:
```
 StreamDeploymentsPath path = new StreamDeploymentsPath("/xd/streams/deployments/my-stream"); assertEquals("my-stream", path.getStreamName()); 
```
It can also be used to build a path, for example:
```
 StreamDeploymentsPath path = new StreamDeploymentsPath().setStreamName("my-stream")... assertEquals("/deployments/streams/my-stream", path.build()); 
```
Note that all fields must be set prior to invoking {@link #build}. @author Patrick Peralta @author Ilayaperumal Gopinathan
