Method Detail

start

public void start(org.osgi.framework.BundleContext context)
           throws java.lang.Exception

Starts up this plugin by reading some extensions and populating the relevant registries.

The global package registry is populated by plugin registration of the form:

  <extension point="org.eclipse.emf.ecore.generated_package" >
      <package uri="http://www.example.org/abc/Abc.ecore" class="org.example.abc.AbcPackage"/>
  <extension>

The URI is arbitrary but an absolute URI is recommended. Provision for access to the serialized model via "http:" is encouraged.

The global resource factory registry's extension map is populated by plugin registration of the form:

  <extension point="org.eclipse.emf.ecore.extension_parser">
      <parser type="abc" class="org.example.abc.util.AbcResourceFactoryImpl"/>
  <extension>

The global resource factory registry's protocol map is populated by plugin registration of the form:

  <extension point="org.eclipse.emf.ecore.protocol_parser" >
      <parser protocolName="abc" class="org.example.abc.util.AbcResourceFactoryImpl"/>
  <extension>

The global URI map is populated by plugin registration of the form:

  <extension point="org.eclipse.emf.ecore.uri_mapping" >
      <mapping source="//special/" target="special/"/>
  <extension>

If the target is relative, it is resolved against the plugin's installed location, resulting in a URI of the form:

  platform:/plugin/plugin-name_1.2.3/...

The above registration would map

  //special/a/b.c

to

  platform:/plugin/plugin-name_1.2.3/special/a/b.c

Specified by:

start in interface org.osgi.framework.BundleActivator

Overrides:

start in class Plugin

Throws:

java.lang.Exception - if there is a show stopping problem.
