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

All Superinterfaces
  Cloneable, Comparable, Expression, Serializable

All Known Implementing Classes:
  LogicalImpl

Deprecated Use `Expression` instead.

    public interface Logical

extends Expression

An expression which does a boolean AND or OR against a list of child expression.

This represents a branch in an expression tree. Its children will be either `Criterias` or other `Logicals`.

Attribute: `children`
- Containment: By Value
- Multiplicity: 0:N
- Interface: java.util.Collection
- This is the list of children Expressions.
Attribute: `logical`

- Containment: By Value
- Multiplicity: 1:1
- The boolean operator, which should be either `TypesHelper.AND` or `TypesHelper.OR`.
