How can i restrict code on prepareForDML method

Question

Hi All,
In my use-case i have created one IMPL class for entity where i override prepareForDML() method and write some code.
this code executed when i change on approveStatus attribute on adf table and press commit button(from DC).
This is fine but problem is that now i change on other attribute of same vo claimed_by and press commit so prepareForDML() method call and same code executed again i don't want this want to bypass prepareForDML() method. or part of code not execute.
Regards

you can check if the desired attribute has been changed or not before executing your method
  protected void prepareForDML(int i, TransactionEvent transactionEvent)
    if(this.isAttributeChanged(YourAttributeIndex))
      //execute your code
    super.prepareForDML(i, transactionEvent);
  }
