| // to take this approach was because it does not include code from the 'common' directory, |
| // which is required in LmJavaSignature class. Hence the helper files were created to |
| // implement the below methods without having to include 'common' code. |
| // So, any change to the signatures in this file will impact the 'sqlutils' code. |
