protected void	configureParameterBeanReferences(PointcutConfig pointcutConfig) Given a pointcut configuration, for all properties configure, fix up and verify any associated bean references.
protected void	createBeanBuilder() Creates the bean builder for the application assembler.
IAOPWeaverProxyBeanBuilder	getAopWeaver() Gets the AOP weaver proxy bean builder DESIGN NOTE: In theory, we could have a AOP proxy bean builder that is different object from the basic proxy bean builder, but I have not coded proxy builders this way, because the reponsibility of creating proxies and instrumenting them usual lies within one module.
void	setAopWeaver(IAOPWeaverProxyBeanBuilder aopWeaver) Sets the AOP weaver proxy bean builder This method calls the superclass method setProxyBeanBuilder
void	start() Start the services registered with the assembly and additionally weaves behaviours into matching service beans and point cuts

Method Detail

createBeanBuilder

protected void createBeanBuilder()

Creates the bean builder for the application assembler. Overrides the superclass method to create or retrieve an IAOPWeaverProxyBeanBuilder

Overrides:

createBeanBuilder in class AbstractServiceAssembler

See Also:

IAOPWeaverProxyBeanBuilder

getAopWeaver

public IAOPWeaverProxyBeanBuilder getAopWeaver()

Gets the AOP weaver proxy bean builder

DESIGN NOTE: In theory, we could have a AOP proxy bean builder that is different object from the basic proxy bean builder, but I have not coded proxy builders this way, because the reponsibility of creating proxies and instrumenting them usual lies within one module. In any case IAOPWeaverProxyBeanBuilder is a sub interface to IProxyBeanBuilder.
Peter Pilgrim

This method calls the superclass method getProxyBeanBuilder

Returns:

Returns the aopWeaver.

See Also:

IProxyBeanBuilder, AbstractServiceAssembler.getProxyBeanBuilder(), setAopWeaver(IAOPWeaverProxyBeanBuilder)

setAopWeaver

public void setAopWeaver(IAOPWeaverProxyBeanBuilder aopWeaver)

Sets the AOP weaver proxy bean builder

This method calls the superclass method setProxyBeanBuilder

Parameters:

aopWeaver - The aopWeaver to set.

See Also:

AbstractServiceAssembler.setProxyBeanBuilder(IProxyBeanBuilder), getAopWeaver()

start

public void start()

Start the services registered with the assembly and additionally weaves behaviours into matching service beans and point cuts

Specified by:

start in interface IStartable

Overrides:

start in class AbstractServiceAssembler

See Also:

AbstractServiceAssembler.start()

weavePointcut

protected void weavePointcut(ContextConfig contextConfig,
                             PointcutConfig pointcutConfig)

Weave a local context pointcut definition that registered an assembler factory.

Add a proxy weaving to the assembler start method.

1. Create a method pointcut
2. Set up the class finder expression
1. If a service-finder tag was specifoed set up the class finder from the service bean's implementation class
3. Set up the method finder expression
4. Retrieve the method interceptor bean. check that it is not a lazy loaded bean and it must be a singleton.

Register the method pointcut with the IAOPWeaverProxyBeanBuilder implementation.

Parameters:

contextConfig - the context configuration

pointcutConfig - the pointcut configuration

configureParameterBeanReferences

protected void configureParameterBeanReferences(PointcutConfig pointcutConfig)

Given a pointcut configuration, for all properties configure, fix up and verify any associated bean references.

Throws:

AssemblyFactoryException - - if the parameters of the pointcut cannot be configured correctly
