    • Method Detail

      • getMimeType

        java.lang.String getMimeType()
        Returns the MIME type of the icon. This method returns the format in which the icon graphics, read from the InputStream object obtained by the getInputStream() method, is encoded.

        The format of the returned string is in accordance to RFC2046. A list of valid MIME types is maintained by the IANA.

        Typical values returned include: "image/jpeg" or "image/gif"

        This method must continue to return the icon MIME type after the UPnP device has been removed from the network.

        Returns:
        The MIME type of the encoded icon.

      • getWidth

        int getWidth()
        Returns the width of the icon in pixels. If the actual width of the icon is unknown, -1 is returned.

        This method must continue to return the icon width after the UPnP device has been removed from the network.

        Returns:
        The width in pixels, or -1 if unknown.

      • getHeight

        int getHeight()
        Returns the height of the icon in pixels. If the actual height of the icon is unknown, -1 is returned.

        This method must continue to return the icon height after the UPnP device has been removed from the network.

        Returns:
        The height in pixels, or -1 if unknown.

      • getSize

        int getSize()
        Returns the size of the icon in bytes. This method returns the number of bytes of the icon available to read from the InputStream object obtained by the getInputStream() method. If the actual size can not be determined, -1 is returned.
        Returns:
        The icon size in bytes, or -1 if the size is unknown.
        Throws:
        java.lang.IllegalStateException - if the UPnP device has been removed from the network.

      • getDepth

        int getDepth()
        Returns the color depth of the icon in bits.

        This method must continue to return the icon depth after the UPnP device has been removed from the network.

        Returns:
        The color depth in bits. If the actual color depth of the icon is unknown, -1 is returned.

      • getInputStream

        java.io.InputStream getInputStream()
                            throws java.io.IOException
        Returns an InputStream object for the icon data. The InputStream object provides a way for a client to read the actual icon graphics data. The number of bytes available from this InputStream object can be determined via the getSize() method. The format of the data encoded can be determined by the MIME type available via the getMimeType() method.
        Returns:
        An InputStream to read the icon graphics data from.
        Throws:
        java.io.IOException - If the InputStream cannot be returned.
        java.lang.IllegalStateException - if the UPnP device has been removed from the network.
