The static method invocation that is used to initialize ccrz.cc_CallContext with information from ccrz.cc_RemoteActionContext and return an instance of ccrz.cc_RemoteActionResult in an Apex @RemoteAction method is ccrz.cc_CallContext.initCallContext(ccrz.cc_RemoteActionContext). This method takes in a ccrz.cc_RemoteActionContext object as a parameter and returns a ccrz.cc_RemoteActionResult object. The ccrz.cc_RemoteActionContext object contains information about the current storefront, user, cart, price list, currency, locale, and session. The ccrz.cc_RemoteActionResult object contains information about the status, result, and errors of the remote action. The other methods are not valid or do not exist.
