Interface Logical

All Known Implementing Classes:

LogicalImpl

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.
