Package org.fcrepo.client

Class FcrepoResponse

java.lang.Object

org.fcrepo.client.FcrepoResponse

All Implemented Interfaces:

Closeable, AutoCloseable

public class FcrepoResponse
extends Object
implements Closeable

Represents a response from a fedora repository using a FcrepoClient.

This class implements Closeable. Suggested usage is to create the FcrepoResponse within a try-with-resources block, insuring that any resources held by the response are freed automatically.

 FcrepoClient client = ...;
 try (FcrepoResponse res = client.get(...)) {
     // do something with the response
 } catch (FcrepoOperationFailedException|IOException e) {
     // handle any exceptions
 }
 

Closed responses have no obligation to provide access to released resources.
