making empty string to Integer null

[Doug Horn]

I am parsing a file where there are Integer fields that are sometimes
empty strings (blank). These are be converted to zeros.

Is there any easy way for empty string to be a null on the Integer
object? I need to know if these fields are blanks or really zeros.

@Field(offset = 4, length = 2, align = Align.RIGHT)
public Integer getAmount() {
return amount;
}

I don't remember off-hand if the converter was for Integer or int (&
your instance is being promoted.) But either way it looks like you'll
need to do custom formatter.

Or you could take the lazy way out: do fixed-format parsing for a
string & then do your own 0/null conversion.
