virtual std::vector<LinkableKnobInfo> DD::Image::LinkableI::getLinkableKnobs ( int  type ) const

pure virtual

Query the object for the knobs that can be linkable with the given type. This type should be one of those as defined in Knobs.h, e.g. XY_KNOB, ARRAY_KNOB, etc.

virtual bool DD::Image::LinkableI::canCreateNewLinkableKnob ( int  type ) const

pure virtual

In some cases, the LinkableI object may be asked if it can create a knob that can be linked to. For example, in the Tracker, you may want to create a new track. The type parameter is the same as used in getLinkableKnobs(int type), e.g. XY_KNOB, ARRAY_KNOB, etc.
