public interface IDebugModelPresentation extends ILabelProvider, ISourcePresentation
org.eclipse.debug.ui.debugModelPresentations implement
this interface. Generally, a debug model implementation will also provide a
debug model presentation extension to render and display its elements. A debug
model presentation is registered for a specific debug model, and is responsible
for the presentation elements defined/implemented by that model.
A debug model presentation extension is defined in plugin.xml.
Following is an example definition of a debug model presentation extension.
<extension point="org.eclipse.debug.ui.debugModelPresentations">
<debugModelPresentation
id="com.example.debugModelIdentifier"
class="com.example.ExamplePresentation"
detailsViewerConfiguration="com.example.ExampleSourceViewerConfiguration">
</debugModelPresentation>
</extension>
The attributes are specified as follows:
id specifies the identifier of the debug model this presentation
is responsible for. Corresponds to the model identifier returned from a debug
element - see IDebugElement.getModelIndentifierclass specifies the fully qualified name of the Java class
that implements this interface.detailsViewerConfiguration optionally specifies the fully qualified name of the Java class
that is an instance of org.eclipse.jface.text.source.SourceViewerConfiguration.
When specified, the source viewer configuration will be used in the "details" area of the
variables and expressions view when displaying the details of an element from the
debug model associated with this debug model presentation. When unspecified,
a default configuration is used.
To allow for an extensible configuration, this interface defines
a setAttribute method. The debug UI plug-in defines
one presentation attribute:
DISPLAY_VARIABLE_TYPE_NAMES - This is a boolean attribute
indicating whether variable elements should be rendered with the declared
type of a variable. For example, a Java debug model presentation would render
an integer as "int x = 3" when true, and "x = 3"
when false.
Clients may define new presentation attributes. For example, a client may wish
to define a "hexadecimal" property to display numeric values in hexadecimal. Implementations
should honor the presentation attributes defined by this interface where possible,
but do not need to honor presentation attributes defined by other clients.
To access the debug model presentation for a debug view, clients should use
IDebugView#getPresentation(String).
Since 3.1, debug model presentations may optionally implement IColorProvider
and IFontProvider to override default fonts and colors for debug elements.
Clients may implement this interface.

When DISPLAY_VARIABLE_TYPE_NAMES is set to true,
this label provider should include the reference type of a variable when rendering
variables. When set to false, this label provider
should not include the reference type of a variable when rendering
