Lets the application respond to the Upload Object request.

Syntax

public class DefaultWebdavserverEventListener implements WebdavserverEventListener {
  ...
  public void uploadObject(WebdavserverUploadObjectEvent e) {}
  ...
}

public class WebdavserverUploadObjectEvent {
  public long connectionID;
  public String path;
  public long restartAt;
  public boolean append;
  public int operationStatus;
}

Remarks

Use this event handler to respond to the received Upload Object request by reserving a place for the new object at Path. This event, if OperationStatus allows, will be followed by a series of WriteObject calls, passing object data in chunks, before a UploadObjectCompleted call signals completion of the upload operation.

Check the operation status, and alter it, if needed, through the OperationStatus parameter:

UploadObjectCompleted Event (Webdavserver Class)

This event is fired when a upload operation completes.

Syntax

public class DefaultWebdavserverEventListener implements WebdavserverEventListener {
  ...
  public void uploadObjectCompleted(WebdavserverUploadObjectCompletedEvent e) {}
  ...
}

public class WebdavserverUploadObjectCompletedEvent {
  public long connectionID;
  public String path;
  public int operationStatus;
}

Remarks

This event is fired when a upload operation completes. This event is only fired for operations handled by the user code, i.e. those intercepted with BeforeUploadFile event, and with Action parameter set to fraCustom.

The ConnectionID parameter specifies the session to which the event belongs, and OperationStatus reports the outcome of the transfer operation.

WriteObject Event (Webdavserver Class)

Hands a piece of object data to the application.

Syntax

public class DefaultWebdavserverEventListener implements WebdavserverEventListener {
  ...
  public void writeObject(WebdavserverWriteObjectEvent e) {}
  ...
}

public class WebdavserverWriteObjectEvent {
  public long connectionID;
  public int operationStatus;
}

Remarks

The class fires this event repeatedly during an overridden upload operation to pass object data to the application.

The handler of this event should retrieve the pending data buffer with a GetClientBuffer call, and write it to the end of the object that is being uploaded.

Use the OperationStatus parameter to return the operation result back to the server.

Set OperationStatus to one of the following values:

Certificate Type

Provides details of an individual X.509 certificate.

Remarks

This type provides access to X.509 certificate details.

Fields

Constructors

public Certificate( bytes,  startIndex,  count,  password);

Loads the X.509 certificate from a memory buffer. Bytes is a buffer containing the raw certificate data. StartIndex and Count specify the starting position and number of bytes to be read from the buffer, respectively. Password is a password encrypting the certificate.

public Certificate( certBytes,  certStartIndex,  certCount,  keyBytes,  keyStartIndex,  keyCount,  password);

Loads the X.509 certificate from a memory buffer. CertBytes is a buffer containing the raw certificate data. CertStartIndex and CertCount specify the number of bytes to be read from the buffer, respectively. KeyBytes is a buffer containing the private key data. KeyStartIndex and KeyCount specify the starting position and number of bytes to be read from the buffer, respectively. Password is a password encrypting the certificate.

public Certificate( bytes,  startIndex,  count);

Loads the X.509 certificate from a memory buffer. Bytes is a buffer containing the raw certificate data. StartIndex and Count specify the starting position and number of bytes to be read from the buffer, respectively.

public Certificate( path,  password);

Loads the X.509 certificate from a file. Path specifies the full path to the file containing the certificate data. Password is a password encrypting the certificate.

public Certificate( certPath,  keyPath,  password);

Loads the X.509 certificate from a file. CertPath specifies the full path to the file containing the certificate data. KeyPath specifies the full path to the file containing the private key. Password is a password encrypting the certificate.

public Certificate( path);

Loads the X.509 certificate from a file. Path specifies the full path to the file containing the certificate data.

public Certificate( stream);

Loads the X.509 certificate from a stream. Stream is a stream containing the certificate data.

public Certificate( stream,  password);

Loads the X.509 certificate from a stream. Stream is a stream containing the certificate data. Password is a password encrypting the certificate.

public Certificate( certStream,  keyStream,  password);

Loads the X.509 certificate from a stream. CertStream is a stream containing the certificate data. KeyStream is a stream containing the private key. Password is a password encrypting the certificate.

public Certificate();

Creates a new object with default field values.

ExternalCrypto Type

Specifies the parameters of external cryptographic calls.

Remarks

External cryptocalls are used in a Distributed Cryptography (DC) subsystem, which allows the delegation of security operations to the remote agent. For instance, it can be used to compute the signature value on the server, while retaining the client's private key locally.

Fields

Constructors

public ExternalCrypto();

Creates a new ExternalCrypto object with default field values.

SocketSettings Type

A container for the socket settings.

Remarks

This type is a container for socket-layer parameters.

Fields

Constructors

public SocketSettings();

Creates a new SocketSettings object.

TLSClientEntry Type

A container for a connected TLS client's details.

Remarks

Use this property to access the details of a particular connected client.

Fields

Constructors

public TLSClientEntry();

Creates a new TLSClientEntry object.

TLSSettings Type

A container for TLS connection settings.

Remarks

The TLS (Transport Layer Security) protocol provides security for information exchanged over insecure connections such as TCP/IP.

Fields

Constructors

public TLSSettings();

Creates a new TLSSettings object.

UserAccount Type

A container for user account information.

Remarks

UserAccount objects are used to store user account information, such as logins and passwords.

Fields

Constructors

public UserAccount();

Creates a new UserAccount object.

WebDAVListEntry Type

Contains a set of attributes of a single WebDAV object.

Remarks

This type represents a single entry returned by the list command.

Fields

Constructors

public WebDAVListEntry();

Creates a new WebDAVListEntry object.

Config Settings (Webdavserver Class)

The class accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.
