preInstall

public void preInstall()

Specified by:

preInstall in interface PluginContext

Overrides:

preInstall in class PluginActivator

shutdown

public void shutdown()

Specified by:

shutdown in interface PluginContext

Overrides:

shutdown in class PluginActivator

introduceTopicType

public void introduceTopicType(TopicType topicType)

Takes care the DeepaMehta standard types (and their parts) get an assignment to the DeepaMehta workspace. This is important in conjunction with access control. Note: type introduction is aborted if at least one of these conditions apply: - A workspace cookie is present. In this case the type gets its workspace assignment the regular way (this plugin's post-create listeners). This happens e.g. when a type is created interactively in the Webclient. - The type is not a DeepaMehta standard type. In this case the 3rd-party plugin developer is responsible for doing the workspace assignment (in case the type is created programmatically while a migration). DM can't know to which workspace a 3rd-party type belongs to. A type is regarded a DeepaMehta standard type if its URI begins with "dm4."

Specified by:

introduceTopicType in interface IntroduceTopicTypeListener
