A source is type of event change that can occur within the workbench. For example, the active workbench window can change, so it is considered a source. Workbench services can track changes to these sources, and thereby try to resolve conflicts between a variety of possible options. This is most commonly used for things like handlers and contexts.
This interface defines the source that are known to the workbench at
compile-time. These sources can be combined in a bit-wise fashion. So, for
example, a ACTIVE_PART | ACTIVE_CONTEXT
source includes change
to both the active context and the active part.
The values assigned to each source indicates its relative priority. The
higher the value, the more priority the source is given in resolving
conflicts. Another way to look at this is that the higher the value, the more
"local" the source is to what the user is currently doing. This is similar
to, but distinct from the concept of components. The nesting support provided
by components represent only one source (ACTIVE_SITE
) that
the workbench understands.
Note that for backward compatibility, we must reserve the lowest three bits
for Priority
instances using the old
HandlerSubmission
mechanism. This mechanism was used in
Eclipse 3.0.
There are unused bits. This is intentional, and is intended to allow clients
space to define their own priorities. The workbench will not add further
priorities in the future without declaring it as a breaking change. If you
want to define your own sources, then you must create a
ISourceProvider
and register it with a workbench service.
This interface is not intended to be implemented or extended by clients.
