Documentation
Definition
Indicates whether the expression is buffered.
Use
Set this indicator if you want the system to invalidate the result of the expression after each query. This means the following:
- The system makes a new calculation of the result of the expression with each new query.
- However, the system does not make a new calculation of the subexpressions that are used.
This means that you can react to a context that might have changed.
Caution:
If you set this indicator, the expression is not buffered. This can have a negative effect on performance.
For this reason, only set this indicator if the following conditions are met:
- The system calculates the expression within an event more than once.
- The calculation of the expression is dependent on the context. This context can be changed during the call of the event (for example, through actions).
- Not all of the subexpressions used are to be calculated anew.
Dependencies
If all of the subexpressions used are to be calculated anew, then you should set Invalidate for buffering.
Example
In an expression whose expression type isRandom Generator you can therefore make a new calculation of the relevant figure. The system also uses as subexpressions constants that should not be calculated anew.
