- For use-cases where the value is required once and then thrown away, applications can read the 'value' property of the ComputedExpression instance obtained from the Expression Manager and use it. Note that this approach will not work for expressions containing remote function calls which are asynchronous by nature (since the 'value' property will not immediately reflect the actual result of evaluation).
- For longer-running use-cases (e.g. a UX field is bound to the result of expression evaluation), applications must bind to the 'value' property of the ComputedExpression instance obtained from the Expression Manager. This property is a bindable property which auto-updates whenever an event occurs which affects the result of evaluation (e.g. a variable value changes, a remote function call returns, etc.). Binding is the only approach which works for expressions containing remote function calls.
