I give an exemple in Python but is a same way for c++ API
mfn_node = OpenMaya.MFnDependencyNode(self.thisMObject())
mfn_node.name()
You want to get node connected to your node in input ? You try to get node
name for use cmds ? it's possible to get with API.
get plug with findPlug function of MFnDependencyNode:
mplug = mfn_node.findPlug(MObject_Attribute)
And use connectedTo of MPlug
mplug.connectedTo(yourPlugArray, True, False) # for get input
mplug.connectedTo(yourPlugArray, False, True) # for get output
mplug.connectedTo(yourPlugArray, True, True) # for get both
You must prefere to get this data in connectionMade function of your
MPxNode rather than the compute.
