= Application state, like app/0x000D0x000A0x000D0x000AApplication state means the actual internal state of application, and also logging.0x000D0x000ASee -ExposingApplicationState-.0x000D0x000A0x000D0x000AThese data points are normally not read from disk at application initialization.0x000D0x000AThey can however normally be accessed from the in-memory data storage as the application progresses.0x000D0x000A0x000D0x000ANote that logging is kind of inbuilt in AgoRapide.0x000D0x000AThe -PropertyStream- / (-RegStream- if you use -ARCEvent-) 'is' the log and if you need to insert additional log0x000D0x000Ainformation they are just new properties to be added to the stream.0x000D0x000A0x000D0x000AA logging console is likewise just a -Client- which subscribes to the whole or part of the -PropertyStream- (for instance like Subscripton = 'as/*'). 0x000D0x000ANOTE: You could have as many log-consoles as you prefer (each with different subscriptions), in order to follow specific parts of the system.0x000D0x000A0x000D0x000AIn addition to the inbuilt log-characteristics of the -PropertyStream- you can insert additional application state data points through two main methods:0x000D0x000A0x000D0x000AMethod A) Call to -Log- (this can also be instructed to log to the local console). Note overloads to this methods encouraging you to supply a set of data-points (set of (key, values) tuples), instead of just some loose text.0x000D0x000ATODO. GIVE EXAMPLE OF THIS.0x000D0x000A0x000D0x000AMethod B) Use a class like -PConcurrent- with concept of -Logger-, this will log any changes to the class (especially useful for exposing -ExposingApplicationState-).0x000D0x000A0x000D0x000ASee also -Log-, -HandleException-, -ExposingApplicationState-.
