Method Detail

set_url

public void set_url(Request req,
                    java.lang.String args)
             throws java.lang.Exception

Throws:

public void set__clone(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

Throws:

java.lang.Exception

set_upload

public void set_upload(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

Throws:

java.lang.Exception

createTransform

protected void createTransform(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.

Throws:

java.lang.Exception

set_download

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

Initiate file download. Unimplemented.

Usage: download dummy_value

Overrides:

set_download in class File

Throws:

VRObjectException

update
