Class GeneratorMapping

java.lang.Object

org.apache.drill.exec.compile.sig.GeneratorMapping

public class GeneratorMapping
extends Object

The code generator works with four conceptual methods which can have any actual names. This class identify which conceptual methods are in use and their actual names. Callers obtain the method names generically using the ClassGenerator.BlockType enum. There is, however, no way to check which methods are in use; the user of this method must already know this information from another source.

Conceptual Method	BlockType	Typical Drill Name
setup	SETUP	doSetup
eval	EVAL	doEval
reset	RESET	?
cleanup	CLEANUP	?
