Description

Interface Summary

ComponentContainer	ContainerImpl is the equivelant of a Service Provider Interface (SPI) for the Expresso component containers.
ComponentLifecycle	Lifecycle interface of an Expresso component.
Configuration	This interface is a read-only interface into a dyna-bean.
Containable	Containable is partially 'marker interface' much like java.lang.Serialiable.
ContainerListener	This class is to provide for event notifications whenever a parent container changes.
Describable	This interface represents an object that can have it's metadata described by an XML file.
ExpressoComponent	Base interface for an Expresso component.
Installable	This interface represents a component that needs to perform install/uninstall work other than recieve straight configuration values.
InstallLog	This class provides an interface wrapper to allow component installation procedures to log their progress.
RootContainerInterface	This interface represents the special container case of the Root container where we need to store specific runtime information.
Startable	This Interface is implemented by any component that has services that 'start' and 'stop'.

Class Summary

ComponentBase	This class provides a convienience base class for the majority of the ExpressoComponent interfaces.
ConsoleInstallLog	This is a default implementation of InstallLog that sends all output to the System console.
ContainerComponentBase	This class provides basic implementations of the Containable Interface to save the typical programmer lots of typing.
DataContext	This class is the code equivilant of the original <context> tag in the older expresso-config files.
DefaultContainerImpl	This class is the default Container Implementation used by the Expresso Framework.
EmbeddedComponent	An Embedded Component is a component that is (1) Not a container and (2) it's metadata is embedded within the metadata of its parent.
InstallationOptions	Installation is a combination metadata and installation flags for a particular component.
InstallParameters	This bean takes the parameters from the Setup screen and passed onto the component manager
LogManager	New LogManager implementation.
RootContainer	This is the default root container interface.
RuntimeInitServlet	This is an initialization servlet that provides a running example on how to load an Expresso runtime system
SystemFactory	This class is the focalpoint class that constructs the Expresso Runtime system.

Package com.jcorporate.expresso.kernel Description

The Expresso Kernel package forms the core interface and basic implementations of the future ECCR or Expresso Component and Configuration Runtime. ECCR will consist of a series of component trees, each tree forms its own configuration interface.

Since:

Expresso 5.3
