Description
By default services are "singleton" scoped which means that clients of a service only ever use a single instance (a singleton) of the service. This behaviour can be changed by specifying a
scope attribute with on the following values:
prototype - A new service is created every time it is injected into another classrequest - A new service will be created per requestflash - A new service will be created for the current and next request onlyflow - In web flows the service will exist for the scope of the flowconversation - In web flows the service will exist for the scope of the conversation. ie a root flow and its sub flowssession - A service is created for the scope of a user sessionsingleton (default) - Only one instance of the service ever exists
