public synchronized void addFlavorListener(FlavorListener listener)
FlavorListener

s from this clipboard.
If listener
is null
, no exception
is thrown and no action is performed.

s in which the current
contents of this clipboard can be provided. If there are no
DataFlavor
s available, this method returns a zero-length
array.

contents of this clipboard can be providedpublic synchronized Transferable getContents(Object requestor)
null
. The parameter Object requestor is
not currently used. The method throws
IllegalStateException
if the clipboard is currently
unavailable. For example, on some platforms, the system clipboard is
unavailable while it is accessed by another application.

The class of the object returned is defined by the representation

so that it no longer
receives FlavorEvent
s from this Clipboard
.
This method performs no function, nor does it throw an exception, if
the listener specified by the argument was not previously added to this
Clipboard
.
If listener
is null
, no exception
is thrown and no action is performed.
listener
- the listener to be removedpublic synchronized void setContents(Transferable contents, ClipboardOwner owner)
If there is an existing owner different from the argument
owner
, that owner is notified that it no longer
holds ownership of the clipboard contents via an invocation
of ClipboardOwner.lostOwnership()
on that owner.
An implementation of setContents()
is free not
to invoke lostOwnership()
directly from this method.
For example, lostOwnership()
may be invoked later on
a different thread. The same applies to FlavorListener
s
registered on this clipboard.
The method throws IllegalStateException
if the clipboard
is currently unavailable. For example, on some platforms, the system
clipboard is unavailable while it is accessed by another application.
contents
- the transferable object representing the
clipboard contentowner
- the object which owns the clipboard content
