- Method Detail
  - getShouldSuppressWarningForThread
```
public static Boolean getShouldSuppressWarningForThread()
```
    Returns whether to suppress the warnings for any expressions evaluated in the current thread
    
    Returns:
    
    true/false or null
  - setShouldSuppressWarningForThread
```
public static void setShouldSuppressWarningForThread(Boolean shouldSuppressWarning)
```
    Sets whether to suppress the warnings for any expressions evaluated in the current thread. NOTE: if calling this, make sure to restore the original value when you are done.
    
    Parameters:
    
    shouldSuppressWarning - true/false or null
  - getShouldSuppressWarning
