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

Class DoubleBivariateFunctionVectorProcessor<TLeftInput,TRightInput>

java.lang.Object

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

All Implemented Interfaces:

ExprVectorProcessor<double[]>

Direct Known Subclasses:

DoubleBivariateDoubleLongFunctionVectorProcessor, DoubleBivariateDoublesFunctionVectorProcessor, DoubleBivariateLongDoubleFunctionVectorProcessor, DoubleBivariateLongsFunctionVectorProcessor

public abstract class DoubleBivariateFunctionVectorProcessor<TLeftInput,TRightInput>
extends Object
implements ExprVectorProcessor<double[]>

common machinery for processing two input operators and functions, which should always treat null inputs as null output, and are backed by a primitive values instead of an object values (and need to use the null vectors instead of checking the vector themselves for nulls) this one is specialized for producing double[], see LongBivariateFunctionVectorProcessor for long[] primitives.
