Class BasicTransferable

  • All Implemented Interfaces:
    java.awt.datatransfer.Transferable
    Direct Known Subclasses:
    DataNodeTransferable
    public class BasicTransferable
extends java.lang.Object
implements java.awt.datatransfer.Transferable
    A basic implementation of the Transferable interface used to implement drag'n'drop operations. It initially supports no DataFlavors, but they can be added by using the various add* methods provided. They should be called in order of priority (most specific first).
