public class ActivityBlotterService
extends java.lang.Object
implements com.caplin.datasource.blotter.BlotterApplicationListener

Handles requests, discards, and deal updates for the activity blotter. - a request occurs when the user logs in and selects the activity blotter - a discard occurs when the blotter is no longer required by the user - deal updates are triggered after a deal is submitted (for example, the deal changes from 'Submitted' to 'Accepted') The activity blotter is a session blotter, so updates outside of a user being logged in and having established a channel can safely be ignored. +----------+ +----------------------+ +-------------------+ |(Blotters)| |ActivityBlotterService| |BlotterDataExtractor| +-----+----+ +----------+-----------+ +---------+---------+ | | | | | | | blotterChannelOpened | | +--------------------->| | | | | | | updateDeal | | |<----------------------| | | | | sendBlotterItem | | |<---------------------| | | | | | | | | | | | | | | blotterChannelClosed | | +--------------------->| | v v v The ActivityBlotterService gets its data from one of the the BlotterDataProviders, which in turn are updated by a combination of the FX API, as the trade progresses through the trade model states, and TrAPI. - (concurrent) stores currently in-use channels in a concurrent map - (longlife) alive continually
