Constructor to create new special comparison Criteria objects.

Parameters:

field - Is the field the criteria is made for.

value - Is the value of this criteria.

operator - Is the compare operator.

typeSuffix - is the type suffix of this criteria. (we use the unqualified class name of the basic Java types ( Boolean,Integer, ...))
