JViews Diagrammer consists of several layers, each
providing a specific set of services for developers during the development
cycle.
JViews Diagrammer implements a Swing-like model-view
architecture, which provides a clear separation between data and its
presentation. The JViews Diagrammer data model is part of the Styling
and Data Mapping (SDM) engine, and it forms the connection between
your application’s data and the views on display. The two principal
responsibilities of the SDM module are notification and styling. When
it receives new data from its back-end data source, the SDM module
automatically notifies all views registered for an update. Likewise,
when the user interacts with views, the model may change.
SDM relies on the services of two underlying layers,
also included in JViews Diagrammer—the Framework SDK and
the Graph Layout SDK.
The Framework SDK sits atop Java 2D™
and
Swing, and provides a comprehensive structured 2D graphics API that
includes graphic objects, interactors, views, transformations, graphs
and subgraphs, editing commands, printing, and thin client support
The Graph Layout SDK provides a set of sophisticated
algorithms to automatically rearrange the graph elements for optimal
readability. Graph layout brings order and clarity to complex diagrams,
moving the nodes and routing to create a more usable picture with
domain-specific aesthetic conventions.
