Class ActivationDataFlavor

    java.lang.Object
      java.awt.datatransfer.DataFlavor
          javax.activation.ActivationDataFlavor

All Implemented Interfaces:
  java.lang.Cloneable, java.io.Externalizable, java.io.Serializable

public class ActivationDataFlavor
extends java.awt.datatransfer.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.

Constructor Detail

### ActivationDataFlavor

    public ActivationDataFlavor(java.lang.Class representationClass,
                                java.lang.String mimeType,
                                java.lang.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 DataFlavor
  `mimeType` - the MIME type of the data represented by this class
  `humanPresentableName` - the human presentable name of the flavor

### ActivationDataFlavor

    public ActivationDataFlavor(java.lang.Class representationClass,
                                java.lang.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 DataFlavor
  `humanPresentableName` - the human presentable name of the flavor

### ActivationDataFlavor

    public ActivationDataFlavor(java.lang.String mimeType,
                                java.lang.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 class
  `humanPresentableName` - the human presentable name of the flavor

Method Detail

### getMimeType

    public java.lang.String getMimeType()

  Return the MIME type for this DataFlavor.

  Returns:
    the MIME type

### getRepresentationClass

    public java.lang.Class getRepresentationClass()

  Return the representation class.

  Returns:
    the representation class

### getHumanPresentableName

    public java.lang.String getHumanPresentableName()

  Return the Human Presentable name.

  Returns:
    the human presentable name

### setHumanPresentableName

    public void setHumanPresentableName(java.lang.String humanPresentableName)

  Set the human presentable name.

  Parameters:
    `humanPresentableName` - the name to set

### equals

    public boolean equals(java.awt.datatransfer.DataFlavor dataFlavor)

  Compares the DataFlavor passed in with this DataFlavor; calls the `isMimeTypeEqual` method.

  Parameters:
    `dataFlavor` - the DataFlavor to compare with
  Returns:
    true if the MIME type and representation class are the same

### isMimeTypeEqual

    public boolean isMimeTypeEqual(java.lang.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.

  Parameters:
    `mimeType` - the MIME type
  Returns:
    true if the same MIME type

### normalizeMimeTypeParameter

    protected java.lang.String normalizeMimeTypeParameter(java.lang.String parameterName,
                                                          java.lang.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.

  Parameters:
    `parameterName` - the parameter name
    `parameterValue` - the parameter value
  Returns:
    the normalized parameter value

### normalizeMimeType

    protected java.lang.String normalizeMimeType(java.lang.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.

  Parameters:
    `mimeType` - the MIME type
  Returns:
    the normalized MIME type
