Method Summary

<T> void	visitClass(java.lang.Class<T> clazz, JavaImplementation type) A callback received when the component implementation class is first loaded
<T> void	visitConstructor(java.lang.reflect.Constructor<T> constructor, JavaImplementation type) A callback received as the component implementation's constructor used for instantiation by the runtime is evaluated.
void	visitConstructorParameter(JavaParameterImpl parameter, JavaImplementation type)
<T> void	visitEnd(java.lang.Class<T> clazz, JavaImplementation type) The final callback received when all other callbacks during evaluation of the component implementation have been issued
void	visitField(java.lang.reflect.Field field, JavaImplementation type) A callback received as the component implementation's public and protected fields are evaluated
void	visitMethod(java.lang.reflect.Method method, JavaImplementation type) A callback received as the component implementation's public and protected methods are evaluated
<T> void	visitSuperClass(java.lang.Class<T> clazz, JavaImplementation type) A callback received as the component implementation class hierarchy is evaluated

Method Detail

visitClass

public <T> void visitClass(java.lang.Class<T> clazz,
                           JavaImplementation type)
                throws IntrospectionException

Description copied from interface: JavaClassVisitor

A callback received when the component implementation class is first loaded

Specified by:

visitClass in interface JavaClassVisitor

Parameters:

clazz - the component implementation class

type - the incomplete component type associated with the implementation class

Throws:

IntrospectionException - if an error is encountered while processing metadata

visitSuperClass

public <T> void visitSuperClass(java.lang.Class<T> clazz,
                                JavaImplementation type)
                     throws IntrospectionException

Description copied from interface: JavaClassVisitor

A callback received as the component implementation class hierarchy is evaluated

Specified by:

visitSuperClass in interface JavaClassVisitor

Parameters:

clazz - the superclass in the component implmentation's class hierarchy

type - the incomplete component type associated with the implementation class

Throws:

IntrospectionException - if an error is encountered while processing metadata

visitMethod

public void visitMethod(java.lang.reflect.Method method,
                        JavaImplementation type)
                 throws IntrospectionException

Description copied from interface: JavaClassVisitor

A callback received as the component implementation's public and protected methods are evaluated

Specified by:

visitMethod in interface JavaClassVisitor

Parameters:

method - the current public or protected method being evaluated

type - the incomplete component type associated with the implementation class

Throws:

IntrospectionException - if an error is encountered while processing metadata

visitConstructor

public <T> void visitConstructor(java.lang.reflect.Constructor<T> constructor,
                                 JavaImplementation type)
                      throws IntrospectionException

Description copied from interface: JavaClassVisitor

A callback received as the component implementation's constructor used for instantiation by the runtime is evaluated. If an implementation contains more than one constructor, the constructor passed to the callback will be chosen according to the algorithm described in the SCA Java Client and Implementation Model Specification.

Specified by:

visitConstructor in interface JavaClassVisitor

Parameters:

constructor - the constructor used for instantiating component implementation instances

type - the incomplete component type associated with the implementation class

Throws:

IntrospectionException - if an error is encountered while processing metadata

visitField

public void visitField(java.lang.reflect.Field field,
                       JavaImplementation type)
                throws IntrospectionException

Description copied from interface: JavaClassVisitor

A callback received as the component implementation's public and protected fields are evaluated

Specified by:

visitField in interface JavaClassVisitor

Parameters:

field - the current public or protected field being evaluated

type - the incomplete component type associated with the implementation class

Throws:

IntrospectionException - if an error is encountered while processing metadata

visitEnd

public <T> void visitEnd(java.lang.Class<T> clazz,
                         JavaImplementation type)
              throws IntrospectionException

Description copied from interface: JavaClassVisitor

The final callback received when all other callbacks during evaluation of the component implementation have been issued

Specified by:

visitEnd in interface JavaClassVisitor

Parameters:

clazz - the component implementation class

type - the incomplete component type associated with the implementation class

Throws:

IntrospectionException - if an error is encountered while processing metadata

visitConstructorParameter

public void visitConstructorParameter(JavaParameterImpl parameter,
                                      JavaImplementation type)
                               throws IntrospectionException

Specified by:
