Mandatory value operation makes nexl throw error if the current value in operations
chain equals to
undefined value.
For example:
${someData*}
If
someData variable is not defined or not provided ( i.e. it equals to
undefined
value ), nexl will throw a "mandatory value" error.
Additionally you can provide your custom error message in the following way:
${someData*Please provide an appropriate arg}
nexl will throw a "Please provide an appropriate arg" error message if
someData
equals
undefined value.
You can also provide an error message dynamically as nexl expression followind by
the
* character:
${someData*${myErrorMsgVar}}
