public class ActivationDataFlavor extends DataFlavor
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.
allHtmlFlavor, fragmentHtmlFlavor, imageFlavor, javaFileListFlavor, javaJVMLocalObjectMimeType, javaRemoteObjectMimeType, javaSerializedObjectMimeType, plainTextFlavor, selectionHtmlFlavor, stringFlavor public ActivationDataFlavor(Class representationClass,
String mimeType,
String humanPresentableName) Construct a DataFlavor that represents an arbitrary Java object. This constructor is an extension of the JDK's DataFlavor in that it allows the explicit setting of all three DataFlavor attributes.
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(Class representationClass,
String humanPresentableName) Construct a DataFlavor that represents a MimeType.
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

Return the MIME type for this DataFlavor.
getMimeType in class DataFlavor
public Class getRepresentationClass()
Return the representation class.
getRepresentationClass in class DataFlavor
public String getHumanPresentableName()
Return the Human Presentable name.

public void setHumanPresentableName(String humanPresentableName)
Set the human presentable name.
setHumanPresentableName in class DataFlavor
humanPresentableName - the name to setpublic boolean equals(DataFlavor dataFlavor)
Compares the DataFlavor passed in with this DataFlavor; calls the isMimeTypeEqual method.
equals in class DataFlavor
dataFlavor - the DataFlavor to compare withDataFlavor.selectBestTextFlavor(java.awt.datatransfer.DataFlavor[])public boolean isMimeTypeEqual(String mimeType)
Is the string representation of the MIME type passed in equivalent to the MIME type of this DataFlavor.
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 typeprotected String normalizeMimeTypeParameter(String parameterName,
String parameterValue) Deprecated.
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. (MIME type parameter values are supposed to be case sensitive).
This method is called for each parameter name/value pair and should return the normalized representation of the parameterValue. This method is never invoked by this implementation.
normalizeMimeTypeParameter in class DataFlavor
parameterName - the parameter nameparameterValue - the parameter valueprotected String normalizeMimeType(String mimeType)
Deprecated.
Called for each MIME type string to give DataFlavor subtypes the opportunity to change how the normalization of MIME types is accomplished. One possible use would be to add default parameter/value pairs in cases where none are present in the MIME type string passed in. This method is never invoked by this implementation.
