## com.beasys.commerce.foundation.expression
Interface Criteria

All Superinterfaces
  Cloneable, Comparable, Expression, Serializable

All Known Implementing Classes:
  CriteriaImpl

Deprecated Use `Expression` instead.

    public interface Criteria

extends Expression

The simple expression container in an expression string.

This will model a property name, an comparision operator, and a value to match against the name. In this fashion simple boolean logic can be utilized.

For use in the personalization and commerce servers, the comparision operator values must be the constants specified in TypesHelper (e.g. EQUALS, NOT_EQUALS, LIKE, etc.). This is because the logic which handles the Criteria objects will compare the operator against those constants.

To create Criteria objects, either use `CriteriaHome.create()` and set property, criteria, and comparator, or use `ExpressionHelper` to parse a query string into an Expression.

Attribute: `criteria`

- Containment: By Value
- Multiplicity: 1:1
- This is the literal value to compare the value of the property against. To operate with a Search object for Content, this should be a java.lang.String, a java.lang.Number, a java.lang.Boolean, a java.sql.Timestamp, or a java.util.Collection of those four. Anything else is considered a USER_DEFINED object and may not work.

Attribute: `property`

- Containment: By Value
- Multiplicity: 1:1
- The name of the property to compare.

Attribute: `scope`

- Containment: By Value
- Multiplicity: 1:1
- The scope of the property to compare.

Attribute: `comparator`

- Containment: By Value
- Multiplicity: 1:1
- The value should one of the nine constants from `TypesHelper` (EQUALS, NOT_EQUALS, GREATER_THAN, LESS_THAN, GREATER_THAN_EQUALS, LESS_THAN_EQUALS, LIKE, CONTAINS, CONTAINS_ALL)
