Property :: instanceLocked - Check whether instance is locked
The function checks, whether the instance has been locked by calling lockInstance() . When the instance is locked, the function returns true. Instances are also locked implicitly, when being read in write mode or stored in a transaction.
When no instance is selected or when the property handle is not valid, the function throws an exception.
Return value: Success ( bool )
The value is true when the function was executed successfully. Otherwise the value is set to false .
