This is the plugin to edit the spredsheet file. Currently, the plugin can only support edit on formula bar. We will continue improving it.
the plugin is actually just a native view controller(ESSEditViewController). the UI is defined in ESSEdit.storyboard file. Globally we introduce(which means stay in memory forever) websocket controller,Global Coordinator, CellViewResourcePool, FormulaHandlerFactory ShareCommonDelegate and OperationCoordinator. Global Coordinator is responsible for load data from server and store all the spreadsheet data in memory. inside GlobalCoordinator, there is one worksheetLoader and one rangeManager. CellViewResourcePool is a resource pool for MultiWorksheetViewController speed up rendering cells on screen. FormulaHandlerFactory is to create FormulaHandler which handles formula related editting. ShareCommonDelegate controls whether spreadsheet file is editable. OperationCoordinator is responsible for send message to server.
Important!!!:The number of method references in a .dex file cannot exceed 64K. Android project use proguard. the plugin is actually a native Activity(InputPageActivity). Globally we introduce ESSWebSocketProcessor, AndroidOperationCoordinator, ConEditChannel, and GlobalAdapter.
