Class ActivationDataFlavor

  • public class ActivationDataFlavor
extends java.lang.Object
    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​(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​(ActivationDataFlavor 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 Jakarta Activation. 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
