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

Interface ExprEvalVector<T>

All Known Implementing Classes:
BaseExprEvalVector, ExprEvalBindingVector, ExprEvalDoubleVector, ExprEvalLongVector, ExprEvalObjectVector
public interface ExprEvalVector<T>
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.)
