Package org.apache.druid.math.expr.vector

Class ExprEvalVector<T>

java.lang.Object

org.apache.druid.math.expr.vector.ExprEvalVector<T>

Direct Known Subclasses:

ExprEvalDoubleVector, ExprEvalLongVector, ExprEvalObjectVector

public abstract class ExprEvalVector<T>
extends Object

Result of ExprVectorProcessor.evalVector(org.apache.druid.math.expr.Expr.VectorInputBinding) which wraps the actual evaluated results of the operation over the input vector(s). Methods to get actual results mirror vectorized value and object selectors. The generic parameter T should be the native java array type of the vector result (long[], Object[], etc.)
