Interface Summary

Interface	Description
ExprVectorProcessor<TOutput>	Interface describing vectorized expression processors, which can be specialized using input type information to produce optimized expression evaluators, which can operate on batches of primitive data with minimal object overhead

Class Summary

Class	Description
BivariateDoubleFunctionVectorValueProcessor<TLeftInput,TRightInput>	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 BivariateLongFunctionVectorValueProcessor for long[] primitives.
BivariateFunctionVectorObjectProcessor<TLeftInput,TRightInput,TOutput>	Base ExprVectorProcessor for expressions and functions with 2 'object' typed inputs (strings, arrays).
BivariateFunctionVectorProcessor<TLeftInput,TRightInput,TOutput>	Basic vector processor that processes 2 inputs and works for both primitive value vectors and object vectors.
BivariateLongFunctionVectorValueProcessor<TLeftInput,TRightInput>	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 long[], see BivariateDoubleFunctionVectorValueProcessor for double[] primitives.

UnivariateDoubleFunctionVectorValueProcessor<TInput>	common machinery for processing single input operators and functions, which should always treat null input as null output, and are backed by a primitive value instead of an object value (and need to use the null vector instead of checking the vector itself for nulls) this one is specialized for producing double[], see UnivariateLongFunctionVectorValueProcessor for long[] primitives.
UnivariateFunctionVectorObjectProcessor<TInput,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)
