Examples of RelationExpression

eu.admire.dispel.expressions.RelationExpression
A representation of the model object 'Relation Expression'.
The following features are supported:
- {@link eu.admire.dispel.expressions.RelationExpression#getChildren Children}
- {@link eu.admire.dispel.expressions.RelationExpression#getRelationOperators Relation Operators}
@see eu.admire.dispel.expressions.ExpressionsPackage#getRelationExpression() @model @generated
org.eclipse.persistence.internal.expressions.RelationExpression

Purpose:Used for all relation operators except for between.
