Package de.janrufmonitor.framework.configuration Description

Handling of configuration data in the framework.

This package offers the posibility to handle configuration data for several components (e.g. services, repository manager or UI components). A component can implement the IConfigurable interface to get automatically informed, when chnages or settings are applied to an configuration property or a complete set of namespaces.
The configuration is handled by a IConfigManager object which is controlled itself by an IConfigManagerFactory. The configuration data is structured in certain way:

1. the configuration object is called property
2. a property consists of a namespace, a name, a metadata and a value
3. the namespace allows to distinguish the same property name for different components
4. the name specifies a unique idetnifier within a namespace of the property
5. the metadata specifies at least one or more identifiers for a property
6. the value contains the data of the property.

Find an Example of a property definition:

     Property for storing a filename:
         

         define {
                namespace = {com.myapps.MyComponent}
                name      = {filename}
                metadata  = {value}
                value     = /etc/var/pim.log
                
                namespace = {com.myapps.MyComponent}
                name      = {filename}
                metadata  = {type}
                value     = Text
                
                namespace = {com.myapps.MyComponent}
                name      = {filename}
                metadata  = {system}
                value     = linux
     }

The definition with an module / plugin file:

com.myapps.MyComponent\:filename\:value=/etc/var/pim.log
com.myapps.MyComponent\:filename\:type=Text
