/**
* A debug model presentation is responsible for providing labels, images, and
* editors associated with debug elements in a specific debug model. Extensions
* of type 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.
*
