Class UiLink

  • Direct Known Subclasses:
    UiDeviceLink, UiEdgeLink, UiRegionDeviceLink, UiRegionLink
    public abstract class UiLink
extends UiElement
    Represents a link (line between two elements). This may be one of several concrete subclasses:
    • An infrastructure link: two backing unidirectional links between two devices.
    • An edge link: representing the connection between a host and a device.
    • An aggregation link: representing multiple underlying UI link instances, for example the link between two sub-regions in a region (layout).

      • UiLink

        public UiLink​(UiTopology topology,
              UiLinkId id)
        Creates a UI link.
        Parameters:
        topology - parent topology
        id - canonicalized link identifier

    • Method Detail

      • id

        public UiLinkId id()
        Returns the canonicalized link identifier for this link.
        Returns:
        the link identifier

      • idAsString

        public String idAsString()
        Description copied from class: UiElement
        Returns a string representation of the element identifier.
        Specified by:
        idAsString in class UiElement
        Returns:
        the element unique identifier

      • type

        public String type()
        Returns the implementing class name as the type of link.
        Returns:
        link type

      • endPointA

        public abstract String endPointA()
        Returns the identifier of end-point A in string form.
        Returns:
        end point A identifier

      • endPointB

        public abstract String endPointB()
        Returns the identifier of end-point B in string form.
        Returns:
        end point B identifier

      • endPortA

        public String endPortA()
        Returns the port number (as a string) for end-point A, if applicable. This default implementation returns null, indicating not-applicable. Subclasses only need to override this method if end-point A has an associated port.
        Returns:
        port number for end-point A

      • endPortB

        public String endPortB()
        Returns the port number (as a string) for end-point B, if applicable. This default implementation returns null, indicating not-applicable. Subclasses only need to override this method if end-point B has an associated port.
        Returns:
        port number for end-point B
