All Implemented Interfaces:
I_CmsConstants, com.opencms.boot.I_CmsLogChannels
public class OpenCms
extends A_OpenCms
implements I_CmsConstants, com.opencms.boot.I_CmsLogChannels

This class is the main class of the OpenCms system, think of it as the "operating system" of OpenCms.

Any request to an OpenCms resource will be processed by this class first. The class will try to map the request to a VFS (Virtual File System) resource, i.e. an URI. If the resource is found, it will be read anf forwarded to to a launcher, which is performs the output of the requested resource.

The OpenCms class is independent of access module to the OpenCms (e.g. Servlet, Command Shell), therefore this class is not responsible for user authentification. This is done by the access module to the OpenCms.

There will be only one instance of the OpenCms object created for any accessing class. This means that in the default configuration, where OpenCms is accessed through a servlet, there will be only one instance of this class running at a time.

Constructor Detail

OpenCms

public OpenCms(source.org.apache.java.util.Configurations conf)
        throws java.lang.Exception
Constructor to create a new OpenCms object.

It reads the configurations from the opencms.properties file in the config/ subdirectory. With the information from this file is inits a ResourceBroker (Database access module), various caching systems and other options.

This will only be done once per accessing class.

Method Detail

createDynamicLinkRules

private void createDynamicLinkRules()
Creates the dynamic linkrules. The CmsStaticExport class needs a CmsObject to create them.

                  throws CmsException
Initialize the startup classes of this OpenCms object.

A startup class has to be configured in the registry.xml file of OpenCms. Startup classes are a way to create plug-in functions that required to be initialized once at OpenCms load time without the need to add initializing code to the constructor of this class.

This must be done only once per running OpenCms object instance. Usually this will be done by the OpenCms servlet.

destroy

public void destroy()
             throws CmsException
Destructor, called when the the servlet is shut down.

Specified by:
destroy in class A_OpenCms

Returns the Class that is used for the password validation.

getStaticExportProperties

public static CmsStaticExportProperties getStaticExportProperties()
Returns the properties for the static export.

getVariantDependencies

public static java.util.Hashtable getVariantDependencies()
Returns the hashtable with the variant dependencies used for the elementcache.
