java.lang.Object

org.mule.runtime.config.spring.dsl.spring.ObjectFactoryClassRepository

public class ObjectFactoryClassRepository
extends Object

Repository for storing the dynamic class generated to mimic FactoryBean from an ObjectFactory. This is done because we need dependency injection and instrospection done over the ObjectFactory without the user knowing about it.

The created FactoryBean is the one that receives the injection of fields declared by the ObjectFactory. It also provides information about the instance type that is creating since it's used to know the order in which beans must be initialised based on the dependencies between them.

The repository has a cache of the created classes based on the configuration of the ComponentBuildingDefinition and the component configuration.

Since:

4.0

getObjectFactoryClass

public Class<ObjectFactory> getObjectFactoryClass(ComponentBuildingDefinition componentBuildingDefinition,
                                                  Class objectFactoryType,
                                                  Class createdObjectType,
                                                  Supplier<Boolean> isLazyInitFunction,
                                                  Consumer<Object> instancePostCreationFunction)

Retrieves a Class for the ObjectFactory defined by the objectFactoryType parameter. Once acquired the Class instance should not be reused for another ComponentBuildingDefinition.

Parameters:

componentBuildingDefinition - the definition on how to build the component

objectFactoryType - the ObjectFactory of the component

createdObjectType - the type of object created by the ObjectFactory

isLazyInitFunction - function that defines if the object created by the component can be created lazily

instancePostCreationFunction - function to do custom processing of the created instance by the ObjectFactory. When there's no need for post processing this value must be Optional.empty()

Returns:

the FactoryBean class to be used by spring for the provided configuration.

destroy

public void destroy()

Removes all registered callbacks create for each created FactoryBean class. This is a must since it prevents a memory leak in CGLIB
