Examples of com.bradmcevoy.http.values.ValueAndType

com.bradmcevoy.http.values.ValueAndType
This class exists to convey type information even when a value is null. This is important because we will often want to select parses and formatters based on knowledge of the type of the value, even when that value is null. @author brad
