## Interface Criterion

- All Known Implementing Classes:
    AndCriterion, CustomCriterion, DateRangeCriterion, DoubleRangeCriterion, FloatRangeCriterion, IntegerRangeCriterion, IsBlankCriterion, IsNullCriterion, LogicalCriterion, LongRangeCriterion, NotBlankCriterion, NotCriterion, NotNullCriterion, OrCriterion, OtherFieldCriterion, RangeCriterion, RelativeDateRangeCriterion, SetCriterion, SimpleCriterion

      public interface Criterion

  An object representing a criterion to apply to a record.

  A criterion is part of the definition of an `AdvancedCriteria` object, which is used to filter records according to search criteria.

  A criterion consists of an operator and typically a fieldName from a Record and a value to compare to. However some operators either don't require a value (eg, isNull) or act on other criteria rather than directly on a Record's fields (eg, the "and" and "or" logical operators).

  See com.isomorphic.criteria.criterion package for Criterion implementations.
