randoop.reflection.DefaultClassVisitor

randoop.reflection.TypeExtractor

All Implemented Interfaces:

ClassVisitor

class TypeExtractor
extends DefaultClassVisitor

TypeExtractor is a ClassVisitor that extracts both the class type, and concrete types that are used in a class as either a parameter, a return type, or a field type.

Field Summary

Fields

Modifier and Type	Field	Description
private Set<Type>	inputTypes	The set of concrete types.
private AccessibilityPredicate	predicate	The accessibility predicate for checking whether a type is accessible in generated tests.

Constructor Summary

Constructors

Constructor	Description
TypeExtractor(Set<Type> inputTypes, AccessibilityPredicate predicate)	Creates a visitor that adds discovered concrete types to the given set if they satisfy the accessibility predicate.

Method Summary

Modifier and Type	Method	Description
private void	addIfConcrete(Type type)	Determines whether the given general type is not generic, and, if so, adds the concrete type to the input types of this object.
void	visit(Class<?> c, ReflectionManager reflectionManager)	Perform action on member class.
void	visit(Constructor<?> c)	Perform action on a constructor.
void	visit(Field f)	Perform an action on a field.
void	visit(Method m)	Perform an action on a method.
void	visitBefore(Class<?> c)	Perform an action on a class.

Constructor Detail

TypeExtractor

TypeExtractor(Set<Type> inputTypes,
              AccessibilityPredicate predicate)

Creates a visitor that adds discovered concrete types to the given set if they satisfy the accessibility predicate.

Parameters:

inputTypes - the set of concrete types

predicate - the accessibility predicate

Method Detail

visit

public void visit(Class<?> c,
                  ReflectionManager reflectionManager)

Description copied from interface: ClassVisitor

Perform action on member class.

The ReflectionManager is needed to allow visitors to initiate recursive visits if needed.

Specified by:

visit in interface ClassVisitor

Overrides:

visit in class DefaultClassVisitor

Parameters:

c - the member class

reflectionManager - the ReflectionManager that called this visitor

visit

public void visit(Constructor<?> c)

Perform action on a constructor.

Adds all concrete parameter types from the constructor to the input types set of this object.

Specified by:

visit in interface ClassVisitor

Overrides:

visit in class DefaultClassVisitor

Parameters:

c - the constructor

visit

public void visit(Method m)

Perform an action on a method.

Adds any concrete type among parameter and return types to the input types set of this object. Avoids bridge methods, because may have rawtypes not useful in building tests.

Specified by:

visit in interface ClassVisitor

Overrides:

visit in class DefaultClassVisitor

Parameters:

m - the method

visit

public void visit(Field f)

Perform an action on a field.

Adds a concrete field type to the input types set of this object.

Specified by:

visit in interface ClassVisitor

Overrides:

visit in class DefaultClassVisitor

Parameters:

f - the field

addIfConcrete

private void addIfConcrete(Type type)

Determines whether the given general type is not generic, and, if so, adds the concrete type to the input types of this object.

Parameters:

type - the general type

visitBefore

public void visitBefore(Class<?> c)

Perform an action on a class. Occurs before other visit methods are called.

Adds the class if it is concrete.

Specified by:

visitBefore in interface ClassVisitor

Overrides:

visitBefore in class DefaultClassVisitor

Parameters:

c - the class to visit
