Overview (Oracle Fusion Middleware Java API Reference for Oracle Extension SDK)

java.lang.Object
- oracle.javatools.ui.overview.Overview<T,M>

Type Parameters:

T - The type of the scale used by the overview (e.g. Float, Integer).

M - The type of OverviewMark that can be added to the Overview

Direct Known Subclasses:

BasicEditorOverview
```
public class Overview<T extends java.lang.Number,M extends OverviewMark<T>>
extends java.lang.Object
```
A class to create and manage an Overview component. An Overview component is a strip down the edge of an editor, or other partially visible component, and containing marks to indicate points of interest over the whole component. e.g. Errors in a source code editor.
The overview has an arbitrary start and end; and marks are placed at locations along this scale. Marks are rendered in a linear scale along the overview.

Marks have a priority, and when marks overlap: marks with lower priorities appear below marks with higher priorities.

Marks can be placed into groups which can all be removed at once.

The overview can optionally display a status indicator to display information about the overview: e.g. "Compiling", "4 Errors, 3 Warnings".

The class is not a component itself, the overview UI component can be obtained via Overview.getGUI() and added to a component hierarchy.
