Introduction

The Application scope is the default "view" for any Application. It presents items in the Application in varying different grouping methods and in different layers:

In versions ≥ 2.19
In versions ≥ 2.18
In versions ≤ 2.17

Accessing the Application scope

To access the Application scope, click the Application scope entry in the Investigation panel - this is default selection when first entering an Application:

Perspective selection

By default, the perspective (how the data is displayed) will be set to CAST Taxonomy (the default layout configured by CAST Imaging) and Level 5 (most detail before individual objects are displayed) - you can find out more about the Perspective options in User Guide - GUI - Investigate panel, however, you are free to choose different perspective options:

Navigating the view

Levels

Levels 1 - 5 are available for selection when CAST Taxonomy aggregation is selected in the Investigate panel - these levels provide ever greater details about the items within the Application. When other aggregation options are enabled (Modules, Services, Architecture Models), only Level 1 and Objects are available:

In CAST Imaging ≥ 2.12.0, Level 4 and Level 5 transaction views will have Reduced Call Graph instead of Full Call Graph.

In CAST Imaging ≥ 2.20.0, selective search modal in Level 5 is consistent with the Global search.

Actions

In ≥ 2.18, Vignettes are replaced by Multiple Tabs (new tab/s).

Action	Location	Result/Behavior
Double click on node	Level 1 - 4	Drill down to the next level.
	Level 5	Drill down to Vignette mode i.e.: Objects level + drill mode Children + Caller/Callee + Group by communities (depending on the object selected). See also User Guide - GUI - Investigate panel for more information on Drill and Communities modes. Click to expand Note that this action is equivalent to the right click options Children + caller/callee. If more than 500 child nodes exist, then a popup will be displayed allowing you to search for the objects you need to view: To use the selective expand: Enter a search term to list matching objects - tick the objects you wish to view (or use the Select All menu): Use the Expand with and Number of objects options to restrict the results:
	Objects and Vignette mode	Expand and investigate the selected object.
Shift + Double click on white space	All levels	Drill up to the next level.
Right click on node	Levels 1 - 4	Properties > Displays information about the node in the right hand slide in panel: If the object properties cannot be retrieved in a timely manner, a retry button will be displayed:
	Level 5	Children + X > Drill down into Vignette mode for further investigation. See also User Guide - GUI - Investigate panel for more information on Drill and Communities modes. Add edge > See User Guide - Working with custom links. Search > Invokes the standard search options for the selected object. See User Guide - Search for items. Properties > Displays information about the node in the right hand slide in panel (see User Guide - Properties panel): If the object properties cannot be retrieved in a timely manner, a retry button will be displayed:
	Vignette mode	Expand All > Expand and investigate the selected node (same as double click) Hide node > Use this to hide selected nodes. To unhide, either use the "Undo" option or refresh the page. It is not possible to hide a concept node or a group node, in which case the option will not be available. Properties > Displays information about the node in the right hand slide in panel (see User Guide - Properties panel): If the object properties cannot be retrieved in a timely manner, a retry button will be displayed:
	Objects	Add callers/callees > Retrieves all caller/called objects. Links are added to the selected object and to any other objects present where a link exists. The number in square brackets in the contextual menu indicates the number of items available. Add linked objects > See User Guide - Using the Add Linked Objects feature for more information. Note that in the current Application scope at Objects level, Imaging does not consider sub-objects for the Add callers/callees and Add linked objects options, therefore the number in square brackets may be less than the number displayed for the same object and contextual menu options when you have searched for the object and displayed it in the view. Path finder > See User Guide - Using the Path Finder feature. Call hierarchy > See User Guide - Using the Call Hierarchy feature. Focus > See User Guide - Using the Focus option. Add 2 levels of Callers/Callees > Same principal as the Add Callers/Callees options, but instead displays two levels of objects. Associate to custom aggregation > See User Guide - Creating a custom aggregation mode. Show source code > See User Guide - Viewing source code. Explain > See User Guide - OpenAI Integration. Highlight Callees/Highlight Callers/Highlight Immediate Callers/Callees/Highlight Path > See User Guide - Using the Highlight options Hide node/object > Use this to hide selected nodes. To unhide, either use the "Undo" option or refresh the page. It is not possible to hide a concept node or a group node, in which case the option will not be available. Remove object > Use this option to remove the object from the current view. When you reload the view the object will be re-displayed. Annotations/Documents > See User Guide - Using the Annotate / Sticky notes feature Properties > Displays information about the object in the right hand slide in panel (see User Guide - Properties panel): If the object properties cannot be retrieved in a timely manner, a retry button will be displayed:
Single click on edge	Levels 1 - 5	N/A
Single click on edge	Objects and Vignette mode	Displays all the methods that are linked between classes and provides additional actions such as: view source code method information add caller/callees See User Guide - Using the Method view for more information.
Double click on edge	Levels 1 - 4	Drill-down to the next level will occur and the node/links involved in the clicked edge will be highlighted. All other nodes will be masked (reduced opacity): Example of double clicking an edge/link in Level 3 - click to enlarge
	Level 5	View will open showing the contents (child objects and caller/callees on child objects - child objects are grouped by object type) of the edge/link that was double clicked. A "vignette" is displayed in the upper left (can be moved as required) to indicate original location of the selected edge/link. Click to enlarge
	Objects and Vignette mode	N/A
