Overview
Scriptable extension service facilitates running the java scripts based DPE extensions. Once the
extension scripts are added in the RDU database, the RDU applies the scripts to the DPE cache. When
the CPE boots and attempts to establish connection with the DPE, the extension scripts are executed
based on the extensions configured in the device property hierarchy.
Script’s Shared Scope
Script’s Shared Scope is a shared repository for extension scripts. Cisco BAC APIs like get properties
from PG, fire extension specific events, debugging, logging, and so on, are put into the Script’s Shared
Scope so that the extension scripts can call them whenever required.
The following objects are added in the Script’s Shared Scope for extension scripts:
