inputOutput.OpenIGTLinkConnection
All Implemented Interfaces:
IOpenIgtPacketListener
public class OpenIGTLinkConnection extends Object implements IOpenIgtPacketListener
builds a connection based on OpenIGTLink for tracking data and image data. As a prerequisite MITK v2016.11 has to run in the background. The connection is established by using the online stream.

    • OpenIGTLinkConnection

      public OpenIGTLinkConnection()
      This constructor establishes a connection to a OpenIGTLink server using the default ip-address and port.

    • OpenIGTLinkConnection

      public OpenIGTLinkConnection(String ip, int port)
      An IP-address and a port number is needed for the connection. Here both are set through the constructor.
      Parameters:
      ip -
      port -

    • onRxImage

      public void onRxImage(String name, ImageMessage image)
      This method is receiving an image as ImageMessage from the server, while it is running in the background during the connection. After getting an ImageMessage, the setImageMessage(ImageMessage img) method is called in order to set the received ImageMessage and the body of ImageMessage is unpacked in order to get the image data, which is also set by calling setImageData(byte[] imgData). The framerate is also determined here.
      Specified by:
      onRxImage in interface IOpenIgtPacketListener
      Parameters:
      name - A string of what type of data to get
      image - the image

    • getImageMessage

      public ImageMessage getImageMessage()

    • setImageMessage

      public void setImageMessage(ImageMessage img)
      This method is for setting an ImageMessage.

    • setImageDataByte

      public void setImageDataByte(byte[] imgData)
      This method is for setting an image data in the form of a byte.

    • getImageDataByte

      public byte[] getImageDataByte()
      This method is for getting the current image data.
      Returns:
      It returns the image data as a byte[]

    • stop

      public boolean stop()
      This method is for stopping the connection (the client).
      Returns:
      client.isInterrupted() is true if closing the connection was successful

    • isConnected

      public boolean isConnected()
      This method is for checking the connection while the application is running.
      Returns:
      isConnected
