Support Classes
|
||||
---------------
|
||||
|
||||
There are a few support classes in this module that make it simpler to build
|
||||
the most common BACnet devices.
|
||||
|
||||
.. class:: CurrentDateProperty(Property)
|
||||
|
||||
This is a long line of text.
|
||||
This class is a specialized readonly property that always returns the
|
||||
current date as provided by the operating system.
|
||||
|
||||
.. method:: ReadProperty(self, obj, arrayIndex=None)
|
||||
|
||||
Returns the current date as a 4-item tuple consistent with the
|
||||
Python implementation of the :class:`Date` primitive value.
|
||||
|
||||
.. method:: WriteProperty(self, obj, value, arrayIndex=None, priority=None)
|
||||
|
||||
Object instances of this class are readonly, so this method raises
|
||||
a `writeAccessDenied` error.
|
||||
|
||||
.. class:: CurrentTimeProperty(Property)
|
||||
|
||||
This is a long line of text.
|
||||
This class is a specialized readonly property that always returns the
|
||||
current local time as provided by the operating system.
|
||||
|
||||
.. method:: ReadProperty(self, obj, arrayIndex=None)
|
||||
|
||||
Returns the current date as a 4-item tuple consistent with the
|
||||
Python implementation of the :class:`Time` primitive value.
|
||||
|
||||
.. method:: WriteProperty(self, obj, value, arrayIndex=None, priority=None)
|
||||
|
||||
Object instances of this class are readonly, so this method raises
|
||||
a `writeAccessDenied` error.
|
||||
|
||||
.. class:: LocalDeviceObject(DeviceObject)
|
||||
|
||||
This is a long line of text.
|
||||
The :class:`LocalDeviceObject` is an implementation of a
|
||||
:class:`DeviceObject` that provides default implementations for common
|
||||
properties and behaviors of a BACnet device. It has default values for
|
||||
communications properties, returning the local date and time, and
|
||||
the `objectList` property for presenting a list of the objects in the
|
||||
device.
