Interface ICombinedContext

All Superinterfaces:
IContext, IDTFJContext
All Known Implementing Classes:
CombinedContext
public interface ICombinedContext extends IDTFJContext
A combined context is an extended DTFJ context which also contains a DDR context. This is to allow commands to be passed down the stack starting with DTFJ and then moving to DDR if necessary.

  • Method Details

    • getID

      int getID()
      Contexts have a unique positive numeric identifier within a session. This number always increases if new contexts are created via the open command rather than attempting to re-use any already used IDs.
      Returns:
      the ID for this context

    • setID

      void setID(int id)
      Sets the numeric ID for this context. This setter is provided so as to allow context creation before assigning the ID. However once set it should not be changed. Later implementations may enforce this.
      Parameters:
      id - the context ID

    • getDDRIObject

      Object getDDRIObject()
      A handle to the underlying DDR interactive session
      Returns:
      a valid session or null if the core file is not DDR enabled

    • getDDRStartupException

      Throwable getDDRStartupException()
      Get the exception which was thrown when trying to start a DDR interactive session.
      Returns:
      the exception or null if the session started without error.

    • displayContext

      void displayContext(IOutputManager out, boolean shortFormat)
      Display the contexts which are present in the core file currently being analysed.
      Parameters:
      shortFormat - true for short format which just displays the first line of the java -version string

    • setAsCurrent

      void setAsCurrent()
      Called when this context becomes the current context to allow any initialisation to take place.

    • isDDRAvailable

      boolean isDDRAvailable()
      Flag to indicate if an associated DDR context is available as well as the DTFJ one.
      Returns:
      true if DDR is available
