Method Detail

getTransferDataFlavors

public java.awt.datatransfer.DataFlavor[] getTransferDataFlavors()

Returns an array of DataFlavor objects indicating the flavors the data can be provided in. The array should be ordered according to preference for providing the data (from most richly descriptive to least descriptive).

Specified by:

getTransferDataFlavors in interface java.awt.datatransfer.Transferable

Returns:

an array of data flavors in which this data can be transferred

isDataFlavorSupported

public boolean isDataFlavorSupported(java.awt.datatransfer.DataFlavor flavor)

Returns whether or not the specified data flavor is supported for this object.

Specified by:

isDataFlavorSupported in interface java.awt.datatransfer.Transferable

Parameters:

flavor - the requested flavor for the data

Returns:

boolean indicating whether or not the data flavor is supported

getTransferData

public java.lang.Object getTransferData(java.awt.datatransfer.DataFlavor flavor)
                                 throws java.awt.datatransfer.UnsupportedFlavorException,
                                        java.io.IOException

Returns an object which represents the data to be transferred. The class of the object returned is defined by the representation class of the flavor.

Specified by:

getTransferData in interface java.awt.datatransfer.Transferable

Parameters:

flavor - the requested flavor for the data

Throws:

java.io.IOException - if the data is no longer available in the requested flavor.

java.awt.datatransfer.UnsupportedFlavorException - if the requested data flavor is not supported.

DataFlavor.getRepresentationClass()

isRicherFlavor

protected boolean isRicherFlavor(java.awt.datatransfer.DataFlavor flavor)

getRicherFlavors

protected java.awt.datatransfer.DataFlavor[] getRicherFlavors()

Some subclasses will have flavors that are more descriptive than HTML or plain text. If this method returns a non-null value, it will be placed at the start of the array of supported flavors.

getRicherData

protected java.lang.Object getRicherData(java.awt.datatransfer.DataFlavor flavor)
                                  throws java.awt.datatransfer.UnsupportedFlavorException

Throws:

java.awt.datatransfer.UnsupportedFlavorException

isHTMLFlavor

protected boolean isHTMLFlavor(java.awt.datatransfer.DataFlavor flavor)

Returns whether or not the specified data flavor is an HTML flavor that is supported.

Parameters:

flavor - the requested flavor for the data

Returns:

boolean indicating whether or not the data flavor is supported

isHTMLSupported

protected boolean isHTMLSupported()

Whether the HTML flavors are offered. If so, the method getHTMLData should be implemented to provide something reasonable.

getHTMLData

protected java.lang.String getHTMLData()

Fetch the data in a text/html format

isPlainFlavor

protected boolean isPlainFlavor(java.awt.datatransfer.DataFlavor flavor)

Returns whether or not the specified data flavor is an plain flavor that is supported.

Parameters:

flavor - the requested flavor for the data

Returns:

boolean indicating whether or not the data flavor is supported

isPlainSupported

protected boolean isPlainSupported()

Whether the plain text flavors are offered. If so, the method getPlainData should be implemented to provide something reasonable.

getPlainData

protected java.lang.String getPlainData()

Fetch the data in a text/plain format.

isStringFlavor

protected boolean isStringFlavor(java.awt.datatransfer.DataFlavor flavor)

Returns whether or not the specified data flavor is a String flavor that is supported.

Parameters:

flavor - the requested flavor for the data

Returns:

boolean indicating whether or not the data flavor is supported
