Uses of ApplyFunction in org.apache.druid.math.expr

Classes in org.apache.druid.math.expr that implement ApplyFunction

Modifier and Type	Class	Description
static class	ApplyFunction.AllMatchFunction	Evaluates to true if all element of the array input Expr causes the LambdaExpr to evaluate to a 'truthy' value
static class	ApplyFunction.AnyMatchFunction	Evaluates to true if any element of the array input Expr causes the LambdaExpr to evaluate to a 'truthy' value
static class	ApplyFunction.BaseFoldFunction	Base class for family of ApplyFunction which aggregate a scalar or array value given one or more array input Expr arguments and an array or scalar "accumulator" argument with an initial value
static class	ApplyFunction.BaseMapFunction	Base class for "map" functions, which are a class of ApplyFunction which take a lambda function that is mapped to the values of an ApplyFunction.IndexableMapLambdaObjectBinding which is created from the outer Expr.ObjectBinding and the values of the array Expr argument(s)
static class	ApplyFunction.CartesianFoldFunction	Accumulate a value for the cartesian product of 'n' array inputs arguments with an 'n + 1' argument LambdaExpr.
static class	ApplyFunction.CartesianMapFunction	Map the cartesian product of 'n' array input arguments to an 'n' argument LambdaExpr
static class	ApplyFunction.FilterFunction	Filter an array to all elements that evaluate to a 'truthy' value for a LambdaExpr
static class	ApplyFunction.FoldFunction	Accumulate a value for a single array input with a 2 argument LambdaExpr.
static class	ApplyFunction.MapFunction	Map the scalar values of a single array input Expr to a single argument LambdaExpr
static class	ApplyFunction.MatchFunction	Base class for family of ApplyFunction which evaluate elements elements of a single array input against a LambdaExpr to evaluate to a final 'truthy' value

Methods in org.apache.druid.math.expr that return ApplyFunction

Modifier and Type	Method	Description
static ApplyFunction	Parser.getApplyFunction(String name)	Get ApplyFunction by NamedFunction.name()

Uses of ApplyFunction in org.apache.druid.math.expr.vector

Methods in org.apache.druid.math.expr.vector with parameters of type ApplyFunction

Modifier and Type	Method	Description
static <T> ExprVectorProcessor<T>	FallbackVectorProcessor.create(ApplyFunction function, LambdaExpr lambdaExpr, List<Expr> args, Expr.VectorInputBindingInspector inspector)	Create a processor for a non-vectorizable ApplyFunction.
