Drag and Drop: New Data Transfer Capabilities in the JavaTM 2 Platform, Standard Edition (J2SETM), version 1.4(4) DataFlavor itself is a class. It makes several default flavor and MIME types available through class constants and a method. Going from simplest to most complex, you get predefined flavors for plain text, strings, a file list, and images. There are also three MIME types defined for local, serialized, and remote objects. From the MIME types, you can create the flavors. getTextPlainUnicodeFlavor stringFlavor JavaFileListFlavor imageFlavor JavaJVMLocalObjectMimeType JavaSerializedObjectMimeType JavaRemoteObjectMimeType
Using the Word processor example, imagine if that Word processor was your program and you wanted to support cut and paste of the content of your document. You might present the content in four different flavors. The first flavor would be the local object type. If cut-and-paste is happening within the same application, using the JavaJVMLocalObjectMimeType allows you to just use a local memory reference for the copy operation. Going between different Java applications would allow you to create a flavor from JavaSerializedObjectMimeType. Here, the content is serialized, and you would be able to preserve any formatting information. The last two are stringFlavor and getTextPlainUnicodeFlavor. Both lose all formatting information, but still permit you to copy the contents.
