listConnections [-connections boolean] [-destination boolean] [-exactType boolean] [-plugs boolean] [-shapes boolean] [-skipConversionNodes boolean] [-source boolean] [-type string]

listConnections is NOT undoable, NOT queryable, and NOT editable.

This command returns a list of all attributes/objects of a specified type that are connected to the given object(s). If no objects are specified then the command lists the connections on selected nodes.

Return value

Long name (short name) Argument types Properties
-source(-s) boolean create
Give the attributes/objects that are on the "source" side of connection to the given object. Default true.
-destination(-d) boolean create
Give the attributes/objects that are on the "destination" side of connection to the given object. Default true.
-plugs(-p) boolean create
If true, return the connected attribute names; if false, return the connected object names only. Default false;
-connections(-c) boolean create
If true, return both attributes involved in the connection. The one on the specified object is given first. Default false.
-shapes(-sh) boolean create
Actually return the shape name instead of the transform when the shape is "selected". Default false.
-type(-t) string create
If specified, only take objects of a specified type.
-exactType(-et) boolean create
When set to true, -t/type only considers node of this exact type. Otherwise, derived types are also taken into account.
-skipConversionNodes(-scn) boolean create
If true, skip over unit conversion nodes and return the node connected to the conversion node on the other side. Default false.
