Class MatrixTurboEvaluator

java.lang.Object

com.github.gbenroscience.parser.turbo.tools.MatrixTurboEvaluator

All Implemented Interfaces:

TurboExpressionEvaluator

public final class MatrixTurboEvaluator
extends Object
implements TurboExpressionEvaluator

Allocation-free Turbo compiler optimized for ParserNG's flat-array Matrix implementation. Uses compile-time bound ResultCaches and Zero-Argument MethodHandle trees to maximize JIT inlining and execution speed.
