Evaluating expressions

When the VM suspends a thread, the debugger supports expression evaluation in the context of a stack frame in that thread.
Note: Evaluations cannot be performed in threads that have been manually suspended.

1. Select the stack frame in which an evaluation is to be performed. For the detail panes of the Variables and Expressions views, the evaluation context will be a selected variable. If no variable is selected, the selected stack frame will be the context.

2. Expressions can be entered and evaluated in the following areas:

   • Display view
   • Detail pane of the Expressions view
   • Detail pane of the Variables view
   • Java editor when it is displaying source and it is not read-only

3. Select the expression to be evaluated and select Display or Inspect from the context pop-up menu. The result of evaluating the expression is shown in the Display view (if Display was chosen), or in the Expressions view (if Inspect was chosen).
