Package org.fcrepo.client

Class FcrepoClient

  • All Implemented Interfaces:
    Closeable, AutoCloseable
    public class FcrepoClient
extends Object
implements Closeable
    Represents a client to interact with Fedora's HTTP API.

    Users of the FcrepoClient are responsible for managing connection resources. Specifically, the underlying HTTP connections of this client must be freed. 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(...).perform()) {
     // do something with the response
 } catch (FcrepoOperationFailedException|IOException e) {
     // handle any exceptions
 }
