Do you mean that you simply want to ensure that the value of a given
attribute in the entity lies between max and min? Or should "match"
be calculated from max and min?
Match is calculated from min and max for each entity: each entity
has a spectrum (an NSArray of NSPoint's) and the two values "min" and
"max" represent a step function.
The "match" value comes from a normalized overlap integral. Hence, if
I sort by "match", that means the filter is the one that matches my
request the best.
I see that my understanding of Bindings and MVC is pretty shallow.
How do I get each entity to use (and know about) the value of min and
max? What is the right approach?
