Returns the value of a given fieldName.
Returns the value of a given fieldName. For primitive types if value is null it returns 'zero value' specific for primitive ie. 0 for Int - use isNullAt to ensure that value is not null
when data type does not match.
IllegalArgumentExceptionwhen fieldName do not exist.
UnsupportedOperationExceptionwhen schema is not defined.
