Class ActivationDataFlavor

java.lang.Object
java.awt.datatransfer.DataFlavor
javax.activation.ActivationDataFlavor
All Implemented Interfaces:
Externalizable, Serializable, Cloneable

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.

    • 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 Details

    • 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
    • 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
