Java javax.activation Class ActivationDataFlavor（JDK8）

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 DataFlavor

  mimeType - the MIME type of the data represented by this class

  humanPresentableName - 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 DataFlavor

  humanPresentableName - 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 class

  humanPresentableName - 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 same

  See 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 name

  parameterValue - 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
