Field Detail

transform

protected org.vrspace.server.Transform transform

Constructor Detail

VrmlFile

public VrmlFile()

Method Detail

set_clone

public void set_clone(org.vrspace.server.Request req,
                      java.lang.String args)
               throws java.lang.Exception

Creates a duplicate of this object. The copy is placed in the database, with a new db_id, and new Transform.

Usage: clone dummy_value

---

set_upload

public void set_upload(org.vrspace.server.Request req,
                       java.lang.String args)
                throws java.lang.Exception

Initiate file upload. Replaces this VrmlFile's url and initiates the file transfer by responding to the client with an upload command. If this VrmlFile does not yet have a Transform, it is assigned one.

Usage: upload path

Overrides:

set_upload in class File

---

createTransform

protected void createTransform(org.vrspace.server.Client client)
                        throws java.lang.Exception

Creates a transform for this VRObject. This method should only be called if a transform does not already exist for the object. The client becomes the owner of the new transform.

---

set_download

public void set_download(org.vrspace.server.Request req,
                         java.lang.String value)
                  throws org.vrspace.server.VRObjectException

Initiate file download. Unimplemented.

Usage: download dummy_value

Overrides:

set_download in class File

---

setValue

public void setValue(org.vrspace.server.Request r)

Overrides PublicDbObject.setValue(). Clone events are filtered and all other requests are passed to super.setValue

Overrides:

setValue in class File

---

update

public void update(java.util.Observable session,
                   java.lang.Object signal)

Implements the Observer interface.

Specified by:

update in interface java.util.Observer

Overrides:

update in class File

---

getTransform

public org.vrspace.server.Transform getTransform()

getTransform method of HasTransform interface.

Specified by:
