Class ReflectVisitorTest

java.lang.Object

org.apache.calcite.util.ReflectVisitorTest

public class ReflectVisitorTest
extends java.lang.Object

ReflectVisitorTest tests ReflectUtil.invokeVisitor(org.apache.calcite.util.ReflectiveVisitor, java.lang.Object, java.lang.Class, java.lang.String) and ReflectiveVisitor and provides a contrived example of how to use them.

Nested Class Summary

Nested Classes

Modifier and Type	Class	Description
class	ReflectVisitorTest.AmbiguousNumber	A class inheriting two interfaces, leading to ambiguity.
class	ReflectVisitorTest.CarefulNumberNegater	CarefulNumberNegater implements NumberNegater in a careful fashion by providing overloads for each known subclass of Number and returning the same subclass for the result.
class	ReflectVisitorTest.CarelessNumberNegater	CarelessNumberNegater implements NumberNegater in a careless fashion by converting its input to a double and then negating that.
class	ReflectVisitorTest.CluelessNumberNegater	CluelessNumberNegater implements NumberNegater in a very broken fashion; does the right thing for Shorts, but attempts to override visit(Object).
static interface	ReflectVisitorTest.CrunchableNumber	An interface for introducing ambiguity into the class hierarchy.
static interface	ReflectVisitorTest.DiceyNumber	Sub-interface of ReflectVisitorTest.FudgeableNumber.
static interface	ReflectVisitorTest.FudgeableNumber	An interface for introducing ambiguity into the class hierarchy.
class	ReflectVisitorTest.IndecisiveNumberNegater	IndecisiveNumberNegater implements NumberNegater in such a way that it doesn't know what to do when presented with an AmbiguousNumber.
class	ReflectVisitorTest.NumberNegater	NumberNegater defines the abstract base for a computation object capable of negating an arbitrary number.
class	ReflectVisitorTest.SomewhatAmbiguousNumber	A class inheriting a root interface (FudgeableNumber) two different ways, which should not lead to ambiguity in some cases.
class	ReflectVisitorTest.SomewhatIndecisiveNumberNegater	SomewhatIndecisiveNumberNegater implements NumberNegater in such a way that it knows what to do when presented with a SomewhatAmbiguousNumber.
