Find SkinCluster using maya.api.OpenMaya


i can easily find SkinCluster with OpenMaya (using MItDependencyGraph) but can’t find a way to do the same with maya.api.OpenMaya

any hint will be appreciated. thanks

Oh… I forgot to say - I need a solution for Maya 2016 Extension 1 (the Maya 2016 Extension 2 has the MItDependencyGraph in Python API 2.0)
