- - org.eclipse.persistence.jpa.jpql.tools.model.query.CompoundExpressionStateObject
  - - org.eclipse.persistence.jpa.jpql.tools.model.query.LogicalExpressionStateObject

All Implemented Interfaces:

StateObject

Direct Known Subclasses:

AndExpressionStateObject, OrExpressionStateObject
```
public abstract class LogicalExpressionStateObject
extends CompoundExpressionStateObject
```
This expression represents a logical expression, which means the first and second expressions are aggregated with either the AND or the OR operator.
