Class BivariateObjectsFunctionVectorProcessor<TLeftInput,TRightInput,TOutput>

java.lang.Object

org.apache.druid.math.expr.vector.BivariateObjectsFunctionVectorProcessor<TLeftInput,TRightInput,TOutput>

All Implemented Interfaces:

ExprVectorProcessor<TOutput>

Direct Known Subclasses:

LongBivariateObjectsFunctionVectorProcessor, ObjectBivariateObjectsFunctionVectorProcessor

public abstract class BivariateObjectsFunctionVectorProcessor<TLeftInput,TRightInput,TOutput>
extends Object
implements ExprVectorProcessor<TOutput>

Base ExprVectorProcessor for expressions and functions with 2 'object' typed inputs (strings, arrays). In SQL compatible null handling mode, for a row with either left or right input as a null value, it will be handled by processNull(int) instead of processIndex(Object, Object, int).
