Package org.silverpeas.kernel

package org.silverpeas.kernel

The technical foundation of all of the Silverpeas projects. It provides all the technical bricks upon which a more functional foundation or solution can be built for Silverpeas. All the interfaces and abstract classes have to be implemented by choosing the more appropriate software solution and the implementations should be available through the Java Service Provider Interface (SPI). Utility classes are also provided for common tasks or needs.

The base key of Silverpeas Kernel is its API abstracting an IoC (Inversion of Control) by IoD (Injection of Dependencies) solution. The idea here is to grant the control flow to frameworks which then delegate functional details to the implementations of some of theirs APIs. These implementations are custom codes provided by the Silverpeas projects. The IoC mechanism allows then the Silverpeas projects to expose their own business or functional interfaces to others projects, to propose one or more implementations of them, and to get transparently an instance of an implementation of a given interface. All the details are taken in charge under the hood by the IoC/IoD solution. Because the code of Silverpeas Kernel must be agnostic to all technical implementation choices, and because there are several and incompatible solutions of an IoC by IoD mechanism, the API is built only upon the JSR-330 and provides a simple way to get programmatically an object satisfying a given type and some qualifiers. The IoC/IoD solution has to be provided through the Java SPI by implementing the BeanContainer interface.
