getOutputType

@Nullable
public ExpressionType getOutputType(Expr.InputBindingInspector inspector,
                                              List<Expr> args)

Description copied from interface: Function

Compute the output type of this function for a given set of argument expression inputs.

Expr.getOutputType(org.apache.druid.math.expr.Expr.InputBindingInspector)

canVectorize

public boolean canVectorize(Expr.InputBindingInspector inspector,
                            List<Expr> args)

Description copied from interface: Function

Check if a function can be 'vectorized', for a given set of Expr inputs. If this method returns true, Function.asVectorProcessor(org.apache.druid.math.expr.Expr.VectorInputBindingInspector, java.util.List<org.apache.druid.math.expr.Expr>) is expected to produce a ExprVectorProcessor which can evaluate values in batches to use with vectorized query engines.
