Method Detail

isResource

public static boolean isResource(java.awt.dnd.DropTargetDropEvent dtde)

Determines whether the specified Drop event describes a Resource.

Parameters:

dtde - the Drop event

Returns:

whether the object being dropped is a Resource

isResource

public static boolean isResource(java.awt.dnd.DropTargetDragEvent dtde)

Determines whether the specified Drag event describes a Resource.

Parameters:

dtde - the Drag event

Returns:

whether the object being dragged is a Resource

acceptDrop

public static int acceptDrop(java.awt.dnd.DropTargetDropEvent dtde,
                             int actions)

Accepts or rejects a drop onto a drop target based on a set of supported actions. The drop must be from the same VM and contain a flavor supported by the target for it to be accepted.

Parameters:

dtde - the DropTargetDropEvent describing the drop event

actions - the set of allowable actions

Returns:

the set of actions from the drop that were accepted, or ACTION_NONE if the drop was rejected

See Also:

java.awt.dnd.DnDConstants.ACTION_NONE

acceptDrag

public static int acceptDrag(java.awt.dnd.DropTargetDragEvent dtde,
                             int supportedActions)

Accepts or rejects a drag over a drop target based on a set of supported actions.

Parameters:

dtde - the DropTargetDragEvent that describes the drag

supportedActions - the set of supported actions

Returns:

the actions for which the drag has been accepted, or ACTION_NONE if the drag was rejected

See Also:

java.awt.dnd.DnDConstants.ACTION_NONE

addConnection

public static java.lang.String addConnection(java.awt.datatransfer.Transferable trans,
                                             javax.naming.Context appContext)
                                      throws javax.naming.NamingException

Adds the connection associated with a Resource to an Application. A Transferable representing a drag from the Resource Navigator is used to determine the Resource and Connection. The specified Application is checked to see if a connection of the same name already exists. If one does, then the connections are checked to see if they are equal. If they are not, the user will be prompted for a new name.

Parameters:

trans - the Transferable from the drop operation

appContext - the Context describing where the connection should be added

Returns:

the name of the connection as it was actually added. This will be different from the connection name in the Resource Navigator if the user chose to rename a connection based on a name conflict.

Throws:

javax.naming.NamingException

addConnection

public static java.lang.String addConnection(java.lang.String id,
                                             javax.naming.Context from,
                                             javax.naming.Context to)

Bind a Connection from source to target.

Parameters:

id -

from -

to -

Returns:

String name under which connection was added, or null if aborted.

addConnection

public static java.lang.String addConnection(java.lang.String connId,
                                             IdeAction action,
                                             Context context,

addConnection

public static java.lang.String addConnection(IdeAction action,
                                             Context context)

Adds a connection to the current active Application/Workspace. Context.selection should have the RepositoryRootNode to be added. Action should be ResCatController.ADD_TO_APPLICATION

Parameters:

action -

context -

performAugmentation

public static oracle.javatools.datatransfer.AugmentableTransferable performAugmentation(java.awt.datatransfer.Transferable trans)

Augments a transferable by performing all transformation supported by the registered DataTranfer plugins.

Parameters:

trans - the Transferable from the drop operation

Returns:

AugmentableTransferable that contains all the flavors supported by the transform plugins.

getResourceURL

public static java.net.URL getResourceURL(java.awt.datatransfer.Transferable trans)

callConnectionHelper
