Viewing and Modifying Variables in the Data Viewer Window
In the Data Viewer window you can inspect and change model parameters as well as Application Builder declarations and Java method variables and Java Shell session variables (long arrays, for example).
The Data Viewer window opens when a method is paused at a breakpoint. It can also be opened from the Windows menu, from the Developer toolbar, or by using the Show in Data Viewer button () in the Java Shell window. In the Java Shell case, the Data Viewer window opens with the Java Shell branch in the tree table is expanded, if present. The Data Viewer window is available in the Application Builder, Model Builder, and Model Manager workspaces. It provides convenient access to all global parameters in a model, which is especially useful when working in the Model Builder workspace.
You find all global primitive declarations, parameters, and Java method and session variables in a table with two columns: Name and Value. They appear under Parameters, Declarations, and Java Shell. For values that are composed of other values (such as arrays and objects), a triangle symbol at the left side makes it possible to expand the variable to display the parts it consists of. This is the case for Declarations and Parameters. Right-click a parameter under Parameters and choose Edit Node to go to the definition of that variable in the model. Right-click a variable under Java Shell and choose Delete from Session to remove that variable from the current Java Shell session. Right-click any parameter or variable and choose Copy (or press Ctrl+C) to copy its name and value.
From the toolbar at the top of the Data Viewer window, you can access the following functionality:
•
If a variable is selected in the Data Viewer and it is part of the model, click the Edit Node button () to go to the definition of a variable in the model.
•
Click the Collapse All button () to collapse the tree in the Data Viewer.
•
Click the Expand Main Levels button () to expand all top nodes so that all variables are visible in the Data Viewer.
From the Collapse All () and Expand Main Levels button ()toolbar menus, you can choose Collapse Selected or Expand Selected to collapse or expand the selected tree branches to main levels (or use the divide and multiply keypad keys, respectively), Collapse Other to collapse all tree branches except the selected ones (or use the Shift key plus the divide keypad key), or Collapse All or Expand All to collapse or expand all branches in the tree.
•
Click the Full Precision button () to toggle full precision for the variables in the Data Viewer on and off.
Underneath the table is an area that displays a pretty-print representation of the selected row in the variable list. according to the following rules:
•
For strings, special characters like newline are displayed, in contrast to the Value column where backslash escape sequences are used.
•
For arrays and matrices, the whole array or matrix is displayed, which is convenient if you want to copy the data into some other program. Note, however, that no more than 100,000 characters are printed in the pretty print area.
You can modify the values in the Value column for variables and declarations such as strings, booleans, and scalar numerical values. For parameters, expand the parameter in the table using the triangle symbol to add an Expression setting where you can edit the parameter’s expression. For Java variables and for declarations in the Application Builder, you see their values underneath the table when selected. For parameters, you see their expressions, values, and descriptions underneath the table when selected. You can also right-click on a row to open a context menu. There you can copy the row data to the clipboard, and if the variable is a model entity (for example, GeomSequence geom = model.geom("geom1")), you can select Edit Node to select the corresponding node in the Model Builder tree or Application Builder tree. You can also right-click the column headers and choose Size Column to Fit or Size All Columns to Fit. One or both columns are then resized to accommodate their content if needed.
