Cat State with Selection Criteria
![[GIF]](../../pics/lines/gray_blue_line.gif)
This framework is described in much better detail in the
Financial Model Framework paper.
These descriptions might have also changed somewhat so the
the above mentioned paper takes precedence over anything written
on these pages.
CatState
CatState is a common repository for information that all
other components might need to access. CatState has four
principle components:
- values - a Dictionary of
ReportValues on the instance side
- selectionBox - a
SelectionBoxValues on the instance side
- windows - an OrderedCollection of Windows on the instance side
- values
- Details from Joe about the new implementation.
- These will need to go
into the class comment also.
- selectionBox
- Holds the current selection criteria. See Selection Criteria
below.
- windows
- Identifies the windows open for the this application.
Unlike the VisualLauncher's windows menus, this collection does not
include development windows or windows for other applications. These windows
are listed in under the Windows menu of a
CatModelWrapper.
This part of CatState should work without changes, for any new business unit.
Selection criteria represent the set of values selected
by the application user, and are implemented via the SelectionCriterion
class. The class has only one instance variable:
- values -- a Dictionary of items used for selection
The purpose of the class is to "project" user desire for information
upon the queries on the database, thus providing the data corresponding
to the selections made.
The GUI for doing this is (and ought) to be written anew for every new
application unless it closely resembles the existing interface class
SelectionBox. Luckily, creation of such classes is greatly simplied by
the Canvas tool.
For more detailed information related to adjusting the SelectionCriterion
class to the requirements of a new application, see the
Porting to New Business Unit section.
