Package org.apache.druid.math.expr

Class Function.StringLongFunction

java.lang.Object

org.apache.druid.math.expr.Function.BivariateFunction

org.apache.druid.math.expr.Function.StringLongFunction

All Implemented Interfaces:

Function, NamedFunction

Direct Known Subclasses:

Function.LeftFunc, Function.RepeatFunc, Function.RightFunc

Enclosing interface:

Function

public abstract static class Function.StringLongFunction
extends Function.BivariateFunction

Base class for a 2 variable input Function whose first argument is a ExprType.STRING and second argument is ExprType.LONG. These functions return null if either argument is null.
