JMeter - call __stringToFile function from Groovy/Beanshell

For example function __machineName can be called from groovy:

def machineName = new org.apache.jmeter.functions.MachineName().compute()

Can anyone advise how can I call function __stringToFile in a similar way?

This function has 4 parameters: 1 - file name 2 - content 3 - append (true/false)(optional) 4 - file encoding (optional)

I would like to pass a Groovy variable (or JMeter variable) as a "content" parametr.

I need to write to a one csv file from severals threads after end of the thread loop and __StringToFile is probably the only one safe way? (prevents "race condition" during writing).

no, it's not (unless you call it under the Critical Section Controller)

If you need to write values from multiple threads into a single file consider using either Sample Variables property or Flexible File Writer

If you're still looking for a way to write a string to file from Groovy it's as simple as:

new File('/path/to/your.file') << 'your string here'
