示例1: change
# 需要导入模块: from framework.controller.controller import Controller [as 别名]
# 或者: from framework.controller.controller.Controller import create_data_change_event_subscription [as 别名]
# - BASE: Represents only a direct change of the node, such as
# replacement, addition or deletion of the node.
# - ONE: Represent a change (addition, replacement, deletion)
# of the node or one of its direct children.
# This scope is a superset of BASE.
# - SUBTREE: Represents a change of the node or any of its child
# nodes, direct and nested.
# This scope is superset of ONE and BASE.
