    Generates code for comparing two expressions.

    Generates code for comparing two expressions.

    dataType

    Holding expressions' mutable states like MonotonicallyIncreasingID.count as a 3-tuple: java type, variable name, code to init it. As an example, ("int", "count", "count = 0;") will produce code:

    private int count;

    as a member variable, and add

    count = 0;

    to the constructor.

    They will be kept as member variables in generated classes like SpecificProjection.
