Detailed Description

The JavaScriptBuilder aggregates JavaScript properties from FlowElements in the pipeline.

This JavaScript also (when needed) generates a fetch request to retrieve additional properties populated with data from the client side It depends on the JSON Bundler element (both are automatically added to a pipeline unless specifically removed) for its list of properties. The results of the JSON Bundler should also be used in a user-specified endpoint which retrieves the JSON from the client side. The JavaScriptBuilder is constructed with a url for this endpoint.

Constructor for JavaScriptBuilder.

Parameters: {object} - options options object; {string} - options.objName the name of the client side object with the JavaScript properties in it; {string} - options.protocol The protocol ("http" or "https") used by the client side callback url. This can be overriden with header.protocol evidence; {string} - options.host The host of the client side callback url. This can be overriden with header.host evidence.; {string} - options.endPoint The endpoint of the client side callback url; {boolean} - options.enableCookies Whether the client JavaScript stored results of client side processing in cookies. This can also be set per request, using the "query.fod-js-enable-cookies" evidence key.
