Examples:
Following is an example of a preference scope declaration. This example declares that this plug-in will provide a preference implementation for the scope "foo". It also declares that when the default values are loaded for this plug-in, the class "MyPreferenceInitializer" contains code to be run to initialize preference default values at runtime.
<extension point=
"org.eclipse.core.runtime.preferences"
>
<scope name=
"foo"
class=
"com.example.FooPrefs"
/>
<initializer class=
"com.example.MyPreferenceInitializer"
/>
<modifier class=
"com.example.MyModifyListener"
/>
</extension>
Supplied Implementation:
The org.eclipse.core.runtime plug-in provides preference implementations for the "configuration", "instance", and "default" scopes. The org.eclipse.core.resources plug-in provides an implementation for "project" preferences.
