Plugins dependencies

The Plugin.getProperty(Object) is called by the PluginsManager to retrieve a Plugin characteristics.

The PluginElementTypes.PROPERTY_DEPEND property allows to specify other plugins (by their name) on which the Plugin depend on. It can contain a single String or a List of Strings.

If one of the Plugins on which a Plugins depends on is not present or is disabled, the dependent Plugin will be disabled.

Result on the Plugins initialization order

If a plugin depends on another plugin, it will be put after the plugin on which it depend on in the initialization order.

Examples

Example with one dependency

In the following example, the "MyPlugin" Plugin depend on the "masterPlugin" Plugin:

      public String getPluginName() {
        return "MyPlugin";
      }

      public Object getPluginProperty(String prop) {
        if (prop.equals(PluginElementTypes.PROPERTY_DATE)) {
          return "26/07/2016";
        } else if (prop.equals(PluginElementTypes.PROPERTY_DESC)) {
          return "My Plugin description";
        } else if (prop.equals(PluginElementTypes.PROPERTY_VERSION)) {
          return "1.0";
        } else if (prop.equals(PluginElementTypes.PROPERTY_DEPEND)) {
          return "masterPlugin";
        }
      }      

Example with several dependencies

In the following example, the "MyPlugin" Plugin depend on the "masterPlugin" and "masterPlugin2" Plugins:

      public String getPluginName() {
        return "MyPlugin";
      }

      public Object getPluginProperty(String prop) {
        if (prop.equals(PluginElementTypes.PROPERTY_DATE)) {
          return "26/07/2016";
        } else if (prop.equals(PluginElementTypes.PROPERTY_DESC)) {
          return "My Plugin description";
        } else if (prop.equals(PluginElementTypes.PROPERTY_VERSION)) {
          return "1.0";
        } else if (prop.equals(PluginElementTypes.PROPERTY_DEPEND)) {
          List list = Arrays.asList(new String[]{"masterPlugin", "masterPlugin2"});
          return list;
        }
      }
