  edu.utep.cs.et.rat.gen.InterfaceValueGenerator

All Implemented Interfaces:

ValueGenerator

 class InterfaceValueGenerator
extends Object
implements ValueGenerator

A class to generate interface values. The approach is to choose randomly a concrete implementation class or subclass from a user-specified list, and to create its instance.

Method Detail

generate

public Denotable generate(Class type,
                          Context ctx,
                          int maxHeight)

Generates a value of the given interface or abstract class type in the given testing context. A concrete implementation class or subclass is chosen randomly from a user-specified list, and its instance created. If no such a concrete class is found, a null value is returned.

Specified by:

generate in interface ValueGenerator

Parameters:

maxHeight - Maximum height of the generated object (viewed as a tree)

getImplClass

private String getImplClass(Class type,
                            Context ctx)

Returns an implementation class of the given type, if any; otherwise, return null.
