Interface ClassVisitor

All Known Implementing Classes:

CheckRepExtractor, ClassLiteralExtractor, DeclarationExtractor, DefaultClassVisitor, OperationExtractor, TestValueExtractor, TypeExtractor

public interface ClassVisitor

ClassVisitor defines the interface for a visitor class that uses reflection to collect information about a class and its members.

Note: if the visitor maintains state relative to visitBefore(Class) and other methods that could be disrupted by visiting member classes (currently just enums), then a stack should be used to maintain whatever state needs to be remembered. For instance, OperationExtractor maintains the declaring class type for visited members, and when inner enums are visited the declaring class needs to be remembered and restored by visitAfter(Class).

Method Detail

visit

void visit(java.lang.Class<?> c,
           ReflectionManager reflectionManager)

Perform action on member class.

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

Parameters:

c - the member class

reflectionManager - the ReflectionManager that called this visitor

visit

void visit(java.lang.reflect.Constructor<?> c)

Perform action on a constructor.

Parameters:

c - the constructor

visit

void visit(java.lang.reflect.Method m)

Perform an action on a method.

Parameters:

m - the method

visit

void visit(java.lang.reflect.Field f)

Perform an action on a field.

Parameters:

f - the field

visit

void visit(java.lang.Enum<?> e)

Perform an action on an enum value.

Parameters:

e - the enum value

visitBefore

void visitBefore(java.lang.Class<?> c)

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

Parameters:

c - the class to visit

visitAfter

void visitAfter(java.lang.Class<?> c)

Perform an action on a class. Called after other visit methods are called.

Parameters:

c - the class to visit
