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

Class UnivariateFunctionVectorObjectProcessor<TInput,TOutput>

java.lang.Object

org.apache.druid.math.expr.vector.UnivariateFunctionVectorObjectProcessor<TInput,TOutput>

All Implemented Interfaces:

ExprVectorProcessor<TOutput>

Direct Known Subclasses:

LongOutObjectInFunctionVectorProcessor

public abstract class UnivariateFunctionVectorObjectProcessor<TInput,TOutput>
extends Object
implements ExprVectorProcessor<TOutput>

common machinery for processing single input operators and functions, which are backed by an object value instead of a primitive value (so do not need to use the null vector, and instead can check the value vector itself for nulls)
