Is the IComponentDefinitions.java needed (in general) for a Participant?


Susan Hanson (1.6k2185193) | asked Jun 13 '14, 8:50 p.m.
I have a few different Participants that I have gotten from different individuals.   Some contain an IComponentDefinitions.java file and some do not.  This IComponentDefinitions.java file contains a static String with a COMPONENT_ID but nothing else.

I'm not clear what these are for or if I need them.  The ones without the file works just fine ... but I have been asked about the use of the file and if they can be removed or not.

Thanks
Susan

Susan, as explained in the Extensions Workshop, you need to define a component.

However, the IComponentDefinitions Java file in this workshop is just an interface, that is used to provide some constants e.g. the component ID. This is not strictly necessary, but can be used e.g. creating error messages.This is strictly optimal and the class is not needed if you code your own extensions.

said a different way, when defining an extension, you MUST have a component element in the plugin.xml

  <extension
            point="com.ibm.team.repository.common.components">
            <component id="com.sd.repository.file.parms"
                name="RTC File Synchronization Service Properties">

and its required attribute id= must contain a unique string value.

you CAN use a class in the bundle to provide that string value.
but this approach is not required.
