Class ParametricImplementationsGroup<T extends ParametricImplementation>

java.lang.Object

io.trino.operator.ParametricImplementationsGroup<T>

Type Parameters:

T - type of implementation details

public class ParametricImplementationsGroup<T extends ParametricImplementation>
extends Object

This class represents set of three collections representing implementations of operators similar to partial template specialization from C++ allowing more optimized implementations to be provided for specific types.
