Class ActivationDataFlavor
java.lang.Object
java.awt.datatransfer.DataFlavor
javax.activation.ActivationDataFlavor
All Implemented Interfaces: Externalizable, Serializable, Cloneable
public class ActivationDataFlavorextends 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.
Since:
1.6

Constructor Detail
ActivationDataFlavor
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
Parameters:representationClass - the class used in this DataFlavormimeType - the MIME type of the data represented by this classhumanPresentableName - the human presentable name of the flavor
ActivationDataFlavor
public 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
Parameters:representationClass - the class used in this DataFlavorhumanPresentableName - the human presentable name of the flavor
ActivationDataFlavor
public ActivationDataFlavor(String mimeType,
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
Parameters:mimeType - the MIME type of the data represented by this classhumanPresentableName - the human presentable name of the flavor
Method Detail
getMimeType
public String getMimeType()
Return the MIME type for this DataFlavor.
Overrides:getMimeType in class DataFlavor
Returns:the MIME type
getRepresentationClass
public Class getRepresentationClass()
Return the representation class.
Overrides:getRepresentationClass in class DataFlavor
Returns:the representation class
getHumanPresentableName
public String getHumanPresentableName()
Return the Human Presentable name.
Overrides:getHumanPresentableName in class DataFlavor
Returns:the human presentable name
setHumanPresentableName
public void setHumanPresentableName(String humanPresentableName)
Set the human presentable name.
Overrides:setHumanPresentableName in class DataFlavor
Parameters:humanPresentableName - the name to set
equals
public boolean equals(DataFlavor dataFlavor)
Compares the DataFlavor passed in with this DataFlavor; calls
the isMimeTypeEqual method.
Overrides:equals in class DataFlavor
Parameters:dataFlavor - the DataFlavor to compare with
Returns:true if the MIME type and representation class
are the sameSee Also:DataFlavor.selectBestTextFlavor(java.awt.datatransfer.DataFlavor[])
isMimeTypeEqual
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.
Overrides:isMimeTypeEqual in class DataFlavor
Parameters:mimeType - the MIME type
Returns:true if the same MIME type
normalizeMimeTypeParameter
protected 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.
Overrides:normalizeMimeTypeParameter in class DataFlavor
Parameters:parameterName - the parameter nameparameterValue - the parameter value
Returns:the normalized parameter value
normalizeMimeType
protected 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.
Overrides:normalizeMimeType in class DataFlavor
Parameters:mimeType - the MIME type
Returns:the normalized MIME type
