Method Summary

Modifier and Type	Method	Description
void	addPlasticClassListener(PlasticClassListener listener)
void	clearCache()	Clears any cached information stored by the proxy factory; this is useful in Tapestry development mode when a class loader may have been discarded (because the proxy factory may indirectly keep references to classes loaded by the old class loader).
<T> T	createProxy(Class<T> interfaceType, Class<? extends T> implementationType, ObjectCreator<T> creator, String description)	Creates a proxy instance that delegates all methods through a corresponding ObjectCreator.
<T> ClassInstantiator<T>	createProxy(Class<T> interfaceType, Class<? extends T> implementationType, PlasticClassTransformer callback)	Same as createProxy(interfacetype, implementationType, callback, true)
<T> ClassInstantiator<T>	createProxy(Class<T> interfaceType, Class<? extends T> implementationType, PlasticClassTransformer callback, boolean introduceInterface)	Creates a proxy object that implements the indicated interface and indicated service implementation type, then invokes the callback to further configure the proxy.
<T> T	createProxy(Class<T> interfaceType, ObjectCreator<T> creator, String description)	Creates a proxy instance that delegates all methods through a corresponding ObjectCreator.
<T> ClassInstantiator<T>	createProxy(Class<T> interfaceType, PlasticClassTransformer callback)	Creates a proxy object that implements the indicated interface, then invokes the callback to further configure the proxy.
<T> PlasticClassTransformation<T>	createProxyTransformation(Class<T> interfaceType)	Creates the underlying PlasticClassTransformation for an interface proxy.
<T> PlasticClassTransformation<T>	createProxyTransformation(Class<T> interfaceType, Class<? extends T> implementationType)	Creates the underlying PlasticClassTransformation for an interface proxy with a given implementation class.
ClassLoader	getClassLoader()	Returns the class loader used when creating new classes, this is a child class loader of another class loader (usually, the thread's context class loader).
Location	getConstructorLocation(Constructor constructor)	Return a string representation for the constructor (including class and parameters) and (if available) file name and line number.
Location	getMemberLocation(Member member, String methodName, String memberTypeDesc, ObjectCreator<String> textDescriptionCreator)
Location	getMethodLocation(Method method)	Converts a method to a Location, which includes information about the source file name and line number.

Method Detail

getClassLoader

public ClassLoader getClassLoader()

Description copied from interface: PlasticProxyFactory

Returns the class loader used when creating new classes, this is a child class loader of another class loader (usually, the thread's context class loader).

Specified by:

getClassLoader in interface PlasticProxyFactory

createProxy

public <T> ClassInstantiator<T> createProxy(Class<T> interfaceType,
                                            Class<? extends T> implementationType,
                                            PlasticClassTransformer callback)

Description copied from interface: PlasticProxyFactory

Same as createProxy(interfacetype, implementationType, callback, true)

Specified by:

createProxy in interface PlasticProxyFactory

Parameters:

interfaceType - interface implemented by proxy

implementationType - a class that implements the interfaceType. It can be null.

callback - configures the proxy

Returns:

instantiator that can be used to create an instance of the proxy class

createProxy

public <T> ClassInstantiator<T> createProxy(Class<T> interfaceType,
                                            Class<? extends T> implementationType,
                                            PlasticClassTransformer callback,
                                            boolean introduceInterface)

Description copied from interface: PlasticProxyFactory

Creates a proxy object that implements the indicated interface and indicated service implementation type, then invokes the callback to further configure the proxy.

Specified by:

createProxy in interface PlasticProxyFactory

Parameters:

interfaceType - interface implemented by proxy

implementationType - a class that implements the interfaceType. It can be null.

callback - configures the proxy

Returns:

instantiator that can be used to create an instance of the proxy class

createProxy

public <T> ClassInstantiator<T> createProxy(Class<T> interfaceType,
                                            PlasticClassTransformer callback)

Description copied from interface: PlasticProxyFactory

Creates a proxy object that implements the indicated interface, then invokes the callback to further configure the proxy.

Specified by:

createProxy in interface PlasticProxyFactory

Parameters:

interfaceType - interface implemented by proxy

callback - configures the proxy

Returns:

instantiator that can be used to create an instance of the proxy class

createProxyTransformation

public <T> PlasticClassTransformation<T> createProxyTransformation(Class<T> interfaceType,
                                                                   Class<? extends T> implementationType)

Description copied from interface: PlasticProxyFactory

Creates the underlying PlasticClassTransformation for an interface proxy with a given implementation class. This should only be used in the cases where encapsulating the PlasticClass construction into a callback is not feasible (which is the case for some of the older APIs inside Tapestry IoC).

Specified by:

createProxyTransformation in interface PlasticProxyFactory

Parameters:

interfaceType - class proxy will extend from

implementationType - a class that implements the interfaceType. It can be null.

Returns:

transformation from which an instantiator may be created

createProxyTransformation

public <T> PlasticClassTransformation<T> createProxyTransformation(Class<T> interfaceType)

Description copied from interface: PlasticProxyFactory

Creates the underlying PlasticClassTransformation for an interface proxy. This should only be used in the cases where encapsulating the PlasticClass construction into a callback is not feasible (which is the case for some of the older APIs inside Tapestry IoC).

Specified by:

createProxyTransformation in interface PlasticProxyFactory

Parameters:

Returns:

transformation from which an instantiator may be created

createProxy

                         String description)

Description copied from interface: PlasticProxyFactory

interfaceType - interface class for proxy

creator - object responsible for creating the real object

description - the toString() of the proxy

Returns:
