java.lang.Objectjava.awt.datatransfer.DataFlavor
javax.activation.ActivationDataFlavor
The ActivationDataFlavor class is a special subclass of
java.awt.datatransfer.DataFlavor
. It allows the JAF to
set all three values stored by the DataFlavor class via a new
constructor. It also contains improved MIME parsing in the equals
method. Except for the improved parsing, its semantics are
identical to that of the JDK's DataFlavor class.

Method Summary | |
boolean |
equals(java.awt.datatransfer.DataFlavor dataFlavor)
Compares the DataFlavor passed in with this DataFlavor; calls the isMimeTypeEqual method. |
java.lang.String |
getHumanPresentableName()
Return the Human Presentable name. |
java.lang.String |
getMimeType()
Return the MIME type for this DataFlavor. |
java.lang.Class |
getRepresentationClass()
Return the representation class. |
boolean |
isMimeTypeEqual(java.lang.String mimeType)
Is the string representation of the MIME type passed in equivalent to the MIME type of this DataFlavor. |
protected java.lang.String |
normalizeMimeType(java.lang.String mimeType)
Called for each MIME type string to give DataFlavor subtypes the opportunity to change how the normalization of MIME types is accomplished. |
protected java.lang.String |
normalizeMimeTypeParameter(java.lang.String parameterName,
java.lang.String parameterValue)
Called on DataFlavor for every MIME Type parameter to allow DataFlavor subclasses to handle special parameters like the text/plain charset parameters, whose values are case insensitive. |
void |
setHumanPresentableName(java.lang.String humanPresentableName)
Set the human presentable name. |

public ActivationDataFlavor(java.lang.Class representationClass, java.lang.String mimeType, java.lang.String humanPresentableName)
The returned DataFlavor will have the following characteristics:
representationClass = representationClass
mimeType = mimeType
humanName = humanName
representationClass
- the class used in this DataFlavormimeType
- the MIME type of the data represented by this classhumanPresentableName
- the human presentable name of the flavorpublic ActivationDataFlavor(java.lang.Class representationClass, java.lang.String humanPresentableName)
The returned DataFlavor will have the following characteristics:
If the mimeType is "application/x-java-serialized-object; class=", the result is the same as calling new DataFlavor(Class.forName()) as above.
otherwise:
representationClass = InputStream
mimeType = mimeType

dataFlavor
- the DataFlavor to compare with
public boolean isMimeTypeEqual(java.lang.String mimeType)
ActivationDataFlavor delegates the comparison of MIME types to the MimeType class included as part of the JavaBeans Activation Framework. This provides a more robust comparison than is normally available in the DataFlavor class.
mimeType
- the MIME type
protected java.lang.String normalizeMimeTypeParameter(java.lang.String parameterName, java.lang.String parameterValue)
This method is called for each parameter name/value pair and should return the normalized representation of the parameterValue.
