Detailed Description

Concrete class for AST Node representing a query part.

A query consists of different query parts For example:

        local y = { @name::(true) && @age::((val > 25) && (val < 35))};

Here, "@age::((val > 25) && (val < 35))" is a query part. The expression before the :: is a key and that after the :: is a value.
