Method Detail

getDataFlavor

public static java.awt.datatransfer.DataFlavor getDataFlavor(java.lang.Object object)

Returns the DataFlavor appropriate for this object.

Parameters:

object - any object

getDataFlavor

public static java.awt.datatransfer.DataFlavor getDataFlavor(java.lang.Class classObj)

Returns the DataFlavor appropriate for this class.

Parameters:

classObj - any class

supportsDataFlavor

public static boolean supportsDataFlavor(java.awt.datatransfer.DataFlavor[] flavors,
                                         java.awt.datatransfer.DataFlavor requested)

Returns true if any of the DataFlavors in the given array support the requested DataFlavor.

Parameters:

flavors - an array of DataFlavors

requested - the requested DataFlavor

supportsDataFlavor

public static boolean supportsDataFlavor(java.awt.datatransfer.DataFlavor base,
                                         java.awt.datatransfer.DataFlavor requested)

Returns true if the base DataFlavor implies support for the requested DataFlavor. This is true if the two data flavors are equal, but also true if the base data flavor uses a subclass of the requested flavor's data class. For example, given:

   DataFlavor colorFlavor = TransferUtils.getDataFlavor(Color.class);
   DataFlavor sysColorFlavor = TransferUtils.getDataFlavor(SystemColor.class);
 

then we have:

   TransferUtils.supportsDataFlavor(sysColorFlavor, colorFlavor); // returns true
   TransferUtils.supportsDataFlavor(colorFlavor, sysColorFlavor); // returns false
 

Parameters:

base - the base DataFlavor

requested - the requested DataFlavor
