I have a QueryBuilder that currently builds a query string. Andy had asked if I could make it build the query object so that we didn't have to parse the string. One of the features of the current method is that it allows you to use the String.format() parameters and replace them before calling the parser. I am looking for a way to do that while building the query objects. I had thought about allowing replacement of the variables with concrete values similar to what the parameterized-sparql-strings does.
