Rogue Wave JViews TGO glossary

A

adapter

An adapter converts business objects into representation objects and pushes these objects into the corresponding representation model. There is a specific adapter for each representation model (that is, table, tree, equipment, and network). An adapter is generally connected to a data source.

B

Bellcore state dictionary

A dictionary of telecommunication object states based on the Bellcore (Bell Communications Research) standard specified in GR-1093 — Generic State Requirements for Network Elements.

blinking manager

A context service that manages the blinking of colors.

BTS

A predefined business object. A BTS (Base Transceiver Station) is a base station composed of antennas that relay (receive and transmit) radio messages within cells of a cellular phone system.

business model

The business model describes the attributes and inheritance of business object classes. It serves as a common vocabulary between Rogue Wave JViews TGO and the back-end application. It does not address relationships between these classes.

business object

An instance of a business class. A business object typically corresponds to a “real” business object somewhere in the back-end application. Business objects represent a subset of the back-end data manipulated by Rogue Wave JViews TGO. They can be shared across multiple graphic components. Rogue Wave JViews TGO furnishes a number of predefined business objects.

See business model. See also the predefined business objects: BTS, card, group, link, network element, off-page connector.

C

card

A predefined business object. An item of equipment that is inserted in a shelf.

card carrier

A predefined business object. A card carrier is a container for shelf item objects. Card carriers allow you to associate more than one card with a single slot.

class manager

A context service that handles a business model. The class manager makes business object classes available to the whole application and allows them to be used by all of the components.

computed attribute

A computed attribute is an attribute of which the value is derived from the value of other attributes. For example, given a start and a finish date, it is possible to calculate a duration.

context

The application context provides access to common contextual data (such as the locale or the current user) and services (such as the URL access service or the class manager).

controller

The controller translates interactions with the view, such as mouse clicks and keystrokes, into updates to be performed on the representation model, instructing the model and/or the view to change as appropriate.

CSS

Cascading Style Sheets. A language that provides rich stylistic control of content to be published on browsers.

CSS2

Cascading Style Sheets, level 2. A style sheet language that allows authors to attach style to structured documents, such as HTML documents or XML applications. CSS2 separates the presentation style from the content and thus simplifies Web authoring and site maintenance.

D

data source

A data source retrieves business objects from a back-end application and transforms them into IlpObject instances. A data source is back-end specific, which means that there is a data source for each type of back end to be addressed.

data source manager

A context service that provides access to the data sources that it handles.

declaration

(CSS.) A property and a corresponding value.

deployment descriptor

A file that defines the application behavior. It is used to initialize an application context.

dictionary visuals

A predefined business object. An empty portion of a shelf that can represent alarms and states graphically.

equipment component

The equipment component is one of the four graphic components provided in Rogue Wave JViews TGO. It is designed to display and interact over telecommunication equipment such as shelves, cards, ports, links and LEDs. The equipment component encapsulates the MVC architecture.

equipment editor

The equipment editor is a graphical user interface which allows you to design and edit equipment elements such as shelves, cards, ports and LEDs.

expansion strategy

A strategy used at the adapter level to identify whether objects should be loaded or not in the representation model. The expansion strategy defines how an object is going to behave when it is expanded. It also indicates whether load on demand is implemented.

G

graphic component

Rogue Wave JViews TGO graphic components encapsulate the MVC triad that clearly separates data from its graphic representation. Rogue Wave JViews TGO provides four main components: the table component, the tree component, the network component, and the equipment component.

See also controller, representation model, view.

graphic holder

A graphic holder is responsible for storing the graphic objects created for a given graphic view. In simple cases, where graphic objects can be recreated when needed, it may not be necessary to store them in a graphic holder.

graphic object

Graphic objects are the graphic representation of their associated representation objects in a graphic view. Graphic objects are optional. They are generally used to draw complex composite objects. Graphic objects are specific to a graphic view, but certain graphic object classes can be shared across graphic components.

graphic view

A graphic view delimits a portion of the screen where the representation objects held by the model are drawn.

See graphic object, view.

group

A predefined business object. A group is a container that holds a set of network elements or links. Groups are used to present a set of network resources grouped logically or geographically.

H

handler

The handler is an optional way of controlling the data source and adapters. When used, the handler is responsible for handling requests coming from its associated graphic component that affect back-end data.

See equipment component, network component.

I

image repository service

A context service used to load all Rogue Wave JViews TGO images.

impact alarm

Impact alarms are used in combination with alarm propagation. An impact alarm corresponds to a propagated alarm, reported by a network element, but carried by another element.

interactor

Interactors translate user gestures and keystrokes into actions to be performed, and more specifically into Swing action invocations. Rogue Wave JViews TGO provides two types of interactor: view interactors that operate on the view as a whole and object interactors that apply to each object contained in the view individually.

J

link

A predefined business object. A link represents a physical connection between two network elements. Links are used to display the transmission elements making up the network lines.

link bundle

A predefined business object. The link bundle object is a link container that you can collapse or expand.

A set of multiple physical point-to-point links between a given pair of systems, combined together into a single logical link with greater bandwidth than any of the constituent component links. The technique of link bundling can be used to increase bidirectional bandwidth, and for redundancy and load balancing.

link factory

The link factory transforms business objects that are links into representation objects that are instances of IlpNetworkLink.

See node factory.

link set

A predefined business object. A link set is used to represent a collection of links between network resources, laid out in a specific order with a specific distance.

load on demand

A feature supported by the network, the equipment and the tree components. It is implemented according to the expansion strategy. It means that the graphic representation of a business object is only created when the parent object is expanded.

M

Misc state dictionary

A dictionary of secondary states that can be used to complement OSI, Bellcore or SNMP standards.

See Bellcore state dictionary, OSI state dictionary SNMP state dictionary, SONET state dictionary.

model

Stores the application objects to be represented in the view. In Rogue Wave JViews TGO, this role is carried out by the representation model.

See MVC.

MVC

The MVC (Model View Controller) architecture is an object-oriented pattern used in user interface design to separate the application object (model) from the way it is represented to the user (view) and from the way in which the user controls it (controller).

See controller, representation model, view.

N

network component

The network component is one of the four graphic components supplied with Rogue Wave JViews TGO. It can display all kinds of Rogue Wave JViews TGO objects: network elements, links, groups, polylines, off-page connectors, cards, card carriers, shelves, ports, LEDs. The network component encapsulates the MVC architecture.

network element

A predefined business object. A network element is any kind of shelf-based telecom or data-communication equipment (such as a switch, a multiplexer, a cross connect system), outside plant equipment (such as a coax nodes), or peripheral equipment (terminal or printer).

node factory

The node factory transforms business objects other than links into representation objects that are instances of IlpNetworkNode .

See link factory.

O

object interactor

An object interactor listens to all user events occurring on a graphic object and sets off the corresponding Swing actions.

See interactor.

pseudoclass

Used in CSS selectors to allow information external to the source, such as whether an anchor has been visited or not, to classify elements.

pseudoelement

Used in CSS selectors to handle typographical items rather than structural items.

R

raw alarm

An alarm reported by a network element and carried by this element.

renderer

A renderer draws a graphic object based on the information retrieved from its associated representation object and business object, if any, using graphic specifications from styles and visual dictionaries. There are two types of renderer: those that implement the default Swing renderer interfaces (only for table and tree) and those that build a graphic object.

representation model

A representation model is a container for representation objects. It is used to produce the graphic objects in the view. The representation model manages the behavior and data of the application domain, responds to requests for information about its state (coming usually from the view), and responds to instructions to change its state (usually issued by the controller).

representation object

A representation object provides the minimal data and structure information required for generating graphic objects, but is totally independent of a particular graphic rendering. More specifically, it does not contain graphic-related information. A representation object is specifically designed to work with a particular graphic component (table, tree, network, and so on) for which it provides a default implementation. A representation object can be linked to a business object, if any, but not necessarily.

See representation model.

rule

(CSS.) A selector and its declarations.

S

SAN state dictionary
