| [higgins-dev] Java classes for attribute values. |
|
Thinking how to best represent a property's value as a Java class, I started working on the table below. Initially, my idea was that each literal type would map either directly to a core Java class, or in cases where an appropriate class didn't exist, would map to something we create (i.e. for xsd:decimal, we create a Decimal class which is basically a String restricted to the range of xsd:decimal.
I'm wondering though, if we maybe want to define a super-class or interface which has methods like
String getLexical(); // returns a lexical string representation of the value
getCanonical(); // returns the canonical string representation of the value
getValue(); // returns the underlying object holding the value (i.e. an Integer for xsd:int)
I'm still thinking about compound attributes. I assume all we need is a single interface which allows one to iterate over the sub-properties of the compound value, where each sub-property is either a literal or compound itself.
Any concerns/comments so far?
