MultipartD1Node (DataONE Java Client Library 2.3.1 API)

java.lang.Object
- org.dataone.client.rest.MultipartD1Node

All Implemented Interfaces:

D1Node

Direct Known Subclasses:

MultipartCNode, MultipartD1Node, MultipartMNode
```
public abstract class MultipartD1Node
extends Object
implements D1Node
```
An abstract node class that contains base functionality shared between Coordinating Node and Member Node implementations. Various methods may set their own timeouts by use of Settings.Configuration properties or by calling setDefaultSoTimeout. Settings.Configuration properties override any value of the DefaultSoTimeout. Timeouts are always represented in milliseconds timeout properties recognized: D1Client.D1Node.listObjects.timeout D1Client.D1Node.getLogRecords.timeout D1Client.D1Node.get.timeout D1Client.D1Node.getSystemMetadata.timeout

Constructor Detail

MultipartD1Node

protected MultipartD1Node(MultipartRestClient client,
                          String nodeBaseServiceUrl,
                          Session session)

Users can set either a default RestClient or default Session that will build a RestClient configured appropriately from the information in the Session.

MultipartD1Node

public MultipartD1Node(MultipartRestClient client,
                       String nodeBaseServiceUrl)

Convenience constructor to create a new instance.

MultipartD1Node

public MultipartD1Node(Session session,
                       String nodeBaseServiceUrl)

Convenience constructor to create a new instance.

@Deprecated
public MultipartD1Node(String nodeBaseServiceUrl)
                            throws IOException,
                                   ClientSideException

Deprecated.

Constructor to create a new instance.

Throws:: ClientSideException; IOException

MultipartD1Node
```
@Deprecated
public MultipartD1Node()
```
Deprecated.

default constructor needed by some clients. This constructor will probably go away so don't depend on it. Use public MultipartD1Node(String nodeBaseServiceUrl) instead.

Utility method to be used in finally blocks for methods that have to close inputStreams. Contrast with IOUtils.closeQuietly(is). Closes the input stream, taking care of null situations, and throwing an appropriate DataONE exception if there is a problem with closing.

Parameters:

Throws:

ServiceFailure
