# This will basically store a list of BACnet objects that the slave will support/implement.
# There will be one instance of this ObjectTable class for each BACnet object type
# (e.g. Binary Value, Analog Input, Multi State Output, ...)
#
# The list of BACnet objects will actually be stored within the self.data variable
# (declared in CustomTable). Self.data will be a list of dictionaries (one entry per BACnet
# object). All of these dictionaries in the self.data list will have entries whose keys actually
# depend on the BACnet type object being handled. The keys in the dictionary will be
# the entries in the PropertyNames list of one of the following classes:
# (BVObject, BOObject, BIObject, AVObject, AOObject, AIObject, MSVObject, MSOObject, MSIObject).
#
# For example, when handling Binary Value BACnet objects,
# self.data will be a list of dictionaries (one entry per row)
# self.data[n] will be a dictionary, with keys "Object Identifier", "Object Name", "Description"
# for example: self.data[n] = {"Object Identifier":33, "Object Name":"room1", "Description":"xx"}
#
# Note that this ObjectTable class merely stores the configuration data.
# It does not control the display nor the editing of this data.
# This data is typically displayed within a grid, that is controlled by the ObjectGrid class.
