Class AbstractNumberParameterHandler

java.lang.Object
  net.sf.twip.parameterhandler.ParameterHandler
      net.sf.twip.parameterhandler.AbstractNumberParameterHandler

Direct Known Subclasses:

AbstractFloatingPointNumberParameterHandler, ByteParameterHandler, EnumParameterHandler, IntegerParameterHandler, LongParameterHandler, ShortParameterHandler

public abstract class AbstractNumberParameterHandler
extends ParameterHandler

You can assume number parameters to be >, >=, !=, <=, or < to a numeric constant. You can assume float and double parameters additionally to be != NaN, != INF, and != -INF. Note that null "slips through" these tests, i.e. if you assume that an Integer argument is >= 0, then null is still passed in.
