StoExCache

java.lang.Object
- de.uka.ipd.sdq.simucomframework.variables.cache.StoExCache

```
public class StoExCache
extends Object
```
A cache for Stoex. This saves the time to parse the stoex again. Caches also the IRandomGenerator which may contain a fixed seed.

Modifier	Constructor	Description
`protected`	`StoExCache(de.uka.ipd.sdq.probfunction.math.IProbabilityFunctionFactory probFunctionFactory)`	Only protected because the cost model should have its own instance of the StoExCache so that it can be resetted independently of the main singleton instance.

    Get a cached stoex parse tree and visitors. If entry is not in the cache it is created and added automatically.
    
    Parameters:
    
    spec - The stoex to search for in the cache
    
    Returns:
    
    The StoExCacheEntry containing the static information on the stoex
