This is a helper class/context manager used with the pdg.AttributeUtils.ignoreWarnings method. The method returns an instance of this context manager, which suppresses parm evaluation warnings caused by invalid @attrib accesses.
For example:
import hou import pdg with pdg.AttributeUtils.ignoreWarnings(): parm = hou.parm("/obj/topnet1/genericgenerator1/itemcount") print(parm.evalAsInt())
