GlideScriptedProcessor - Scoped

ServiceNow processors are equivalent to Java servlets.

Processors provide a customizable URL endpoint that can execute arbitrary server-side JavaScript code and produce output such as TEXT, JSON, or HTML. The ScopedGlideScriptedProcessor APIs are used in processor scripts to access the the processor (servlet) capabilities. There are no constructors for the ScopedGlideScriptedProcessor APIs. The methods are called using the global variable g_processor.

A useful global variable, g_target, is available in processor scripts. It contains the table name extracted from the URL.

The URL to a processor has the format: https://<instance name.servicenow.com>/<path endpoint>.do?<parameter endpoint>=<value> where the path endpoint and parameter endpoint are defined on the processor form.
