1. A method of processing a multi-state attribute field query, comprising:

  • instantiating a plurality of live objects;

    performing, by each live object, an attribute operation, wherein at least one attribute operation is a comparison operation associated with attributes of the query;

    performing the comparison operation by de-referencing associated attribute operands and loading the attribute operands into registers without an intermediate step of placing the operands into a structure for further manipulation;

    accessing, by any of the plurality of live objects, a global status storage area only when an operand of the comparison operation is null or error; and

    passing, from each live object, execution control of the respective attribute operation to an adjacent live object.
