[DEPRECATED] Script: Class dw.svc.ServiceRegistry

Class ServiceRegistry

The ServiceRegistry is responsible for managing Service definitions and their instances.

Typical usage involves several steps:

  1. The service is defined in the Business Manager and configured with necessary credentials.

  2. The service callback is configured once during cartridge initialization:

    ServiceRegistry.configure("MyFTPService", { mockExec : function(svc:FTPService, params) { return [ { "name": "file1", "timestamp": new Date(2011, 02, 21)}, { "name": "file2", "timestamp": new Date(2012, 02, 21)}, { "name": "file3", "timestamp": new Date(2013, 02, 21)} ]; }, createRequest: function(svc:FTPService, params) { svc.setOperation("list", "/"); }, parseResponse : function(svc:FTPService, listOutput) { var x : Array = []; var resp : Array = listOutput; for(var i = 0; i < resp.length; i++) { var f = resp[i]; x.push( { "name": f['name'], "timestamp": f['timestamp'] } ); } return x; } });

  3. A new service instance is created and called in order to perform the operation:

    var result : Result = ServiceRegistry.get("MyFTPService").call(); if(result.status == 'OK') { // The result.object is the object returned by the 'after' callback. } else { // Handle the error. See result.error for more information. }

See ServiceCallback for all the callback options, and individual ServiceDefinition classes for customization specific to a service type.

Deprecated:

It is recommended to use the LocalServiceRegistry instead of this class.

This Service Definition is shared across all Service instances returned by get(String).

Parameters:

serviceID - Unique Service Id

Returns:

ServiceDefinition

isConfigured

static isConfigured(serviceID : String) : boolean

Returns the status of whether the given service has been configured with a callback.

Parameters:

serviceID - Unique Service ID.
