public abstract class AbstractBusinessContextFactory
extends java.lang.Object
implements BusinessContextFactory

This class provides an abstract implementation of the business context factory. This factory class is used to create service provider interface objects for a specified business context. It also provides some helper methods that concrete business context factory class can use.

Constructor Detail

AbstractBusinessContextFactory

public AbstractBusinessContextFactory()

The do-nothing zero-argument constructor.

AbstractBusinessContextFactory

public AbstractBusinessContextFactory(java.util.List paramList)

This method constructs an AbstractBusinessContextFactory object with the given parameters.

Parameters:

paramList - the list of parameters for this factory

Method Detail

createContextSPI

public ContextSPI createContextSPI(ActivityToken token,
                                   com.ibm.commerce.component.contextservice.ActivityData initData)

This method creates a service provider interface object for the context associated with a given activity and initialization data. As there could be more than one context implementation, this method first calls the getContextSPIImplClassname(ActivityToken, ActivityData) method. The getContextSPIImplClassname(ActivityToken, ActivityData) method uses the initialization data to determine which implementation class to use. Once the appropriate implementation class is known, this method calls the createContextSPIClass(String) method to retrieve its instance.

Specified by:

createContextSPI in interface BusinessContextFactory

Parameters:

token - the token of the activity that the context is to be associated with

initData - the data that will determine which implementation class to use. If the factory class is not attribute-based, this parameter is ignored.

Returns:

The service provider interface object.

destroyContextSPI

public void destroyContextSPI(ContextSPI ctxSPI)

This method returns a given context service provider interface object to the pool.

Specified by:

destroyContextSPI in interface BusinessContextFactory

Parameters:

ctxSPI - the service provider interface object to be returned
