activator.java

此源码程序实现的是eclipse开发工具中插件的开发实现参考程序

package cn.com.chengang.myplugin;

import org.eclipse.jface.resource.ImageDescriptor;
import org.eclipse.ui.plugin.AbstractUIPlugin;
import org.osgi.framework.BundleContext;

public class Activator extends AbstractUIPlugin {
	public static final String PLUGIN_ID = "cn.com.chengang.myplugin";
	private static Activator plugin;

	public Activator() {
		plugin = this;
	}

	public static Activator getDefault() {
		return plugin;
	}

	@Override
	public void start(BundleContext context) throws Exception {
		super.start(context);
	}

	@Override
	public void stop(BundleContext context) throws Exception {
		plugin = null;
		super.stop(context);
	}

	public static ImageDescriptor getImageDescriptor(String path) {
		return imageDescriptorFromPlugin(PLUGIN_ID, path);
	}
}
