Class grendel.ui.MessageDisplayManager

java.lang.Object
   |
   +----grendel.ui.MessageDisplayManager

Handles attempts to view messages, folders and their contents, without assuptions about the UI layout. Potential side affects for given actions are detailed. The resulting window state should be order independent if overlapping arguments are the same with the exception of window focus. That is,

 displayMaster(folderA);
 displayFolder(folderA, messageA);
 

should result in the same windows and selections as

 displayFolder(foldarA, messageA);
 displayMaster(folderA);
 

but the result of

 displayFolder(folderA, messageA);
 displayMaster(folderB):
 

is undefined. If multiple windows are opened as the result of multiple calls, focus will be shifted to the last opened window. Focus will always be shifted to the last acted upon view.
