Examples of vectorExpression

org.apache.hadoop.hive.ql.exec.vector.expressions.VectorExpression
Base class for expressions.
org.xvr.s3D.vectorExpression
A representation of the model object 'vector Expression'.
The following features are supported:
- {@link org.xvr.s3D.vectorExpression#getHead Head}
- {@link org.xvr.s3D.vectorExpression#getTail Tail}
@see org.xvr.s3D.S3DPackage#getvectorExpression() @model @generated
