示例1: subscribe
# 需要導入模塊: from neutron_lib.callbacks import events [as 別名]
# 或者: from neutron_lib.callbacks.events import BEFORE_DELETE [as 別名]
def subscribe():
registry.subscribe(
vpn_router_gateway_callback, resources.ROUTER_GATEWAY,
events.BEFORE_DELETE)
registry.subscribe(
vpn_router_gateway_callback, resources.ROUTER_INTERFACE,
events.BEFORE_DELETE)
registry.subscribe(
migration_callback, resources.ROUTER, events.BEFORE_UPDATE)
registry.subscribe(
subnet_callback, resources.SUBNET, events.BEFORE_DELETE)
# NOTE(armax): multiple VPN service plugins (potentially out of tree) may
# inherit from vpn_db and may need the callbacks to be processed. Having an
# implicit subscription (through the module import) preserves the existing
# behavior, and at the same time it avoids fixing it manually in each and
# every vpn plugin outta there. That said, The subscription is also made
# explicitly in the reference vpn plugin. The subscription operation is
# idempotent so there is no harm in registering the same callback multiple
# times. 示例2: subscribe_registries
