Extension Points

I18N for Layouts

Usage	Use this when the layout of a plug-in needs to be localized.
Attributes	point="com.softwareag.cis.plugin.i18n" id class project (name of the plug-in directory) prefix (as used by messages) file (name of the property file to be used)
Interface	I18NHandler
Standard class	Common18NHandler
Processing	Class I18NManager inside PluggableUI handles this extension point. If an I18Message or a text ID in a layout definition (as created using the Application Designer) refers to a source ID that starts with the given prefix, the I18Manager attempts to resolve this reference using the given property file. In the case of a text ID, the corresponding layout must be part of the plug-in whose directory is indicated by the project attribute.

Example	<extension point= "com.softwareag.cis.plugin.connectionHandler" id="login" class="com.centrasite.control.ext. CentraSiteConnectionHandler"> </extension>

Perspectives

Perspectives allow certain predefined screen layouts to be stored. When several perspectives are defined, it is possible to switch from one to the other easily. The Perspective button is visible if more than one perspective is available. When you click the button, a popup dialog appears, which allows you to select the required perspective. The perspective can be switched either by selecting one or more rows (perspectives) and clicking OK or by double-clicking on a single row.

Multiple perspectives will be represented in a way that the union of the corresponding topics is displayed on the right-hand side. The header changes depending on the perspective to which the currently selected topic belongs.

The following features are provided for perspectives:

A fixed set of perspectives as configured through extensions. You can switch a perspective using the Select Perspective dialog.

A fixed set of topics per perspective. The association between topics and the corresponding perspective is established through the plug-in configuration file. Each declaration of a topic extension must contain a reference to the ID of the associated perspective extension.

A perspective may contribute the following components:

A name and an icon being used to represent the perspective in the Select Perspective dialog.

An ICONLISTInfo object used to create a toolbar in the header frame. This can be suppressed if the perspective's supportsViews() method returns false.

The label and valid values for the View list box. This can be suppressed.

A tailored layout to be used as the workplace background. This is only used if the perspective is used as the initial perspective. For more information, see Setting Preferred Plug-in and Order of Plug-ins.

Usage	Each plug-in may contribute a perspective to contain its own topics or the topics of other plug-ins
Attributes	point="com.softwareag.cis.plugin.perspective" id class
Interface	Perspective String getTitle() (used in dynamically generated Select Perspective dialog) String getImageURL() (used to represent a perspective by an icon in the Select Perspective dialog) Toolbar: ICONLISTInfo getToolbar() Logo String getLogoImageURL () (used for header frame) Handling of the View listbox: String getViewLabel() String[] getViewValues() String getView() (returns the currently selected view) void setView(String view) (called when the user changes the view selection) Default layout used for perspective background String getWorkplaceDefaultLayout(); (used for background of workplace if no activity is opened)

If a perspective is selected for display, all topics belonging to that perspective become visible. If one of these perspectives is selected in the navigation pane, the content of the header frame is adjusted with respect to the toolbar, the View listbox, and the visible logo.

Topic

Usage	Add a topic in the navigation view.
Attributes	point="com.softwareag.cis.plugin.topic" id perspective class
Interface	Topic String getImageURL() boolean isVisible() (used when switching views)
Abstract base class	AbstractTopic

Provided by	CentraSite Control
Example	<extension point="com.centrasite.control.registryObjectProperty" id="test" class="com.centrasite.control.extpt.junit. LastModifiedPropertyAccessor"> </extension>

Note:
Additional columns may also show up in upper table of the General tab.

Tab in Detail View

Usage	Add a tab in the detail view of an object.
Attributes	point="com.centrasite.control.detailViewTab" id class
Interface	DetailViewTab String getTitle() String getImageURL() String getLayout() void initAdapterFor (Item, DetailViewTabAdapter) protected String getAdapterClass(); boolean appliesTo (Item) (If this is returned, the tab will be displayed for the corresponding Item if isVisible() returns true as well, otherwise the tab will not be displayed) void setDetailsTabContext (DetailTabContext) boolean isVisible(Item)
Abstract base class	AbstractDetailViewTab
Processing	If the detail view for an Item is opened, it is checked for each known extension. Create an instance of class and invoke appliesTo(Item). If true is returned, getLayout() is invoked and the layout is added as a tab. The respective adapter is created implicitly by the Application Designer when processing the layout. The title of the tab is set with the result from calling getTitle(). Currently, items on tabs are not supported. Hence, the result from getImageURL() is ignored.

Usage	Change the visual representation of registry objects
Attributes	point="com.centrasite.control.assocNavigatorNodeDecorator" id (default: name of implementing class) class
Interface	NodeDecorator String getImageURL(Item)
Abstract base class	(none)
Processing	If the item is to be rendered in Impact Analysis, check all known extensions to determine whether they contribute to the item's visualization. If getImageURL(item) returns null: check for the next extension. Else, use the URL being returned for secondary icon within visualization of node in graphical impact analysis.
Provided by	CentraSite Control
Example	<extension point="com.centrasite.control.assocNavigatorNodeDecorator" id="ExternalLinkNodeDecorator" class="com.centrasite.control.ext.ExternalLinkNodeDecorator"> </extension>

Usage	Append a root node to an existing topic.
Attributes	point="com.centrasite.control.topicItems" id class
Interface	TopicItems boolean appliesTo (Topic) Collection getItems()
Abstract base class	AbstractTopicItems
Processing	For each topic whose implementation class is derived from a class named BaseTopic (true for all topics contributed by CentraSite Control) it is checked whether there are any extension for the topicItems extension point. Each extension whose appliesTo() method returns true, the collection of Item objects returned by getItems() is appended to the set of root nodes for the corresponding topic.
Provided by	CentraSite Control
Example	<extension point="com.centrasite.control.topicItems" id="filesystem" topic="com.centrasite.control.administration" class="com.centrasite.control.ext.junit.

Interface	ItemEditor public boolean appliesTo (Item item, Connector connector); public String getLayout(); public String getTitle(Item item); public String getAdapterClass(); (must return a class implementing the ItemEditorAdapter interface)
Abstract base class	AbstractItemEditor
Processing	If appliesTo() returns true, the editor is used when opening the detail for the item being passed: The given adapter class will be instantiated and initialized. The given layout (=pageURL) is opened in the CONTENT frame on the right-hand side. The title returned by getTitle() is used as the label for the activity.
Provided by	CentraSite Control
Example	<extension point="com.centrasite.control.itemEditor" id="DataType" class="com.softwareag.centrasite.ext.DataTypeEditor"> </extension>

Extend Search Dialog by Additional Conditions

Usage	Extend the search dialog by additional conditions, for example, you can add specific search predicates for your own object types.
Attributes	point="com.centrasite.control.searchPredicate" id class
Interface	PredicateEditor Predicate getPredicate() (Get predicate to be added by this editor) String getLayout() (Get URL of layout to be rendered) String getAdapterClass() (Get name of adapter class to be used for rendering, must be a subclass of AbstractPredicateAdapter) String getPredicateClass() (Get name of predicate class to be used for rendering, must be a subclass of AbstractPredicate)
	The interface Predicate (many implementing classes are already available in CentraSiteUtils.jar) with its abstract subclass AbstractPredicate has the following methods: boolean appliesTo(String objectTypeValue, CentraSiteQueryManager qm) (Check whether this predicate applies to objects of given object type) String getInternalType () (Get unique internal string representation of type of predicate; not to be localized. You may use a namespace-like notation for your own.) String getDisplayType () (Get human readable localized representation of type of predicate; CentraSite Control will display it on the left hand side in the Add Condition dialog) void validate() throws InvalidPredicateException (Validate parameters set for this predicate. The InvalidPredicateException should contain a localized message text) String getDisplayString () throws Exception (Get human readable localized string representation of predicate including values predicate; CentraSite Control displays it in the condition table in the header section of the Search Registry dialog) boolean requiresEnterpriseLicense() (Check whether this predicate requires an Enterprise license) void addTo (BusinessQuery bq) throws JAXRException (Add contribution of predicate to given BusinessQuery. This is the worker method applying the predicate to the search result.)
	AbstractPredicate also provides implementations for the following methods: Used for I18N support Locale getLocale() Void setLocale(Locale) used for persisting predicates as part of queries. String toXML (); void setFromDom(Element predicateEement, Connection connection) used to initialize the search dialog with read only predicates or conditions, which can not be modified or removed: void setReadOnly(boolean readOnly); boolean isReadOnly();
Abstract base class	AbstractPredicateEditor

Example	<extension point="com.centrasite.control.searchPredicate" id="ObjectTypePredicateEditor" class="com.centrasite.control...ObjectTypePredicateEditor"> </extension>

Download Documents

There is a menu entry in each asset's context menu that allows you to create a zipped archive of the asset and optionally any attached documents, and to download the zipped archive to the file system. You can customize the way in which the download feature behaves:

You can make the download entry in the context menu visible or invisible for users with the Guest role.

You can change the text string displayed in the context menu.

You can change the format of the zipped archive.

If a user with the Guest role can access an asset and view its context menu, the context menu entry Download Document is visible by default. You can specify whether this entry is visible or invisible for such users as follows:

To make the download menu entry visible or invisible for guest users

1. Locate the configuration file plugin.xml in the <RuntimeDir>\workspace\webapps\PluggableUI\CentraSiteControl directory.

2. Open the file and locate the following entry:

3. To make the context menu entry invisible for guest users, change true to false and restart Software AG Runtime. Similarly, if the context menu entry is already invisible and you want to make it visible for guest users, set the value to true and restart Software AG Runtime.

Changing the text string displayed in the Context menu

The text string displayed in the context menu is by default Download Document. You can change this by extending the CentraSite Control functionality through the extension point downloadDocumentCommand. This extension point has the following definition:

Usage	Change the text string displayed in the context menu for downloading an asset.
Attributes	com.centrasite.control.downloadDocumentCommand id (default: name of implementing class) class
Interface	See the sample code.
Abstract base class	AbstractExtensionCommand
Provided by	CentraSite Control
Example	See the sample code.

To change the text displayed for the context menu, the implementation of the extension point must define a method getName() of type String. The return value of this method is the text that will be displayed in the context menu.

You can find sample code for defining the extension point in the file DownloadDocumentCustomCommand.java that is provided in the demo folder under the CentraSite installation folder.

Changing the format of the zipped archive

By default, the zipped archive contains the folder structure of the asset and its attached documents. You can change this by extending the CentraSite Control functionality through the extension point downloadDocumentCommand.

To change the format of the zipped archive, your implementation of the extension point must define a method that extends the base class DownloadOperation.

You can find sample code for defining the extension point in the files DownloadDocumentCustomCommand.java and DownloadCustomOperation.java that are provided in the demo folder under the CentraSite installation folder.

Attach Documents

Some assets include file-related attributes that allow you to attach supporting document(s) such as programming guides, sample code, and script files with the asset. While trying to attach a supporting document with an asset, CentraSite Control displays the available documents underneath their respective organization directory by default. You can change this (that is, simply display the documents by the side of its organization directory) by extending the CentraSite Control functionality through the extension point attachDocumentCommand.

To customize the document layout

1. Locate the configuration file plugin.xml in the <RuntimeDir>\workspace\webapps\PluggableUI\CentraSiteControl directory.

2. Open the file and locate the following entry:

Where com.centrasite.control.extpt.AttachDocumentCustomCommand is the name of the abstract base class that implements the interface.

3. To define your custom document layout, change false to true and restart Software AG Runtime. Similarly, if the document layout is already customized and you want to revert to the standard layout, set the value to false and restart Software AG Runtime.

Usage	Use this to define a custom layout of the documents while attaching to an asset through the Attach Document dialog.
Attributes	com.centrasite.control.attachDocumentCommand id (default: name of implementing class) class
Interface	See the sample code.
Abstract base class	AbstractExtensionCommand
Processing	When you click the appropriate button, this invokes the user-defined Adapter (layout) screen displaying all documents that are available for attaching to an asset. Create an instance of the class Execute
Provided by	CentraSite Control
Example	<extension point="com.centrasite.control.attachDocumentCommand" id="AttachDocumentCustomCommand" class="com.centrasite.control. extpt.AttachDocumentCustomCommand" />

You can find sample code for defining the extension point in the files AttachDocumentCustomCommand.java, AttachFile.xml, and AttachFileAdapter.java that are provided in the demos folder under the CentraSite installation folder.
