Subject determining whether a feature has been set
Date Mon, 03 May 2010 13:15:27 GMT
is there any way to determine whether a feature of a primitive
numerical type has been set in a particular feature structure? The
methods like getIntValue(feat), getFloatValue(feat), etc. all return a
zero value if the feature hasn't been set. But zero is of course a
perfectly plausible value in many domains.
