ArgumentRequiredError

pentaho.lang. ArgumentRequiredError

The ArgumentRequiredError class is the class of errors for a function's argument that was required but was not specified, or was specified but with a nully or empty value.

The name of the argument can be that of a nested property. For example: "keyArgs.description".

An argument being "required" may mean that an argument must be:

• Specified: if(arguments.length&lt1) ...
• Truthy: if(!value) ...
• Not nully: if(value == null) ...
• Not nully or an empty string: if(value == null || value ==="") ...
