| Can I append additional identifier data to a Resource ? [message #62608] |

I have a data file that contains many independently
editable text items. Is there a way to append internal
identifier data to, say, an IPath?
I'm particularly interested in the case where the
Resource is obtained on opening a Marker. I need
my editor to locate the data inside the specified
resource. It seems that creating a Bookmark
(for example) fails because it checks for the
existence of the Resource.
Something like what is supported by web browsers
on URLs when additional data is needed (they
use # and ? separators depending on the situation).
Thanks in advance,
Campbell

Hi.
You might want to check out Markers. Markers are used to persist resource
metadata.
Check out extension point org.eclipse.core.resources.markers.
Markers are added to resources via IResource.createMarker(String identifier)
The identifier is the same as the identifier in the extension point.
Markers are (as far as I know) magically stored in the workspace, unless
they are declared as Transient.
Check out IMarker interface also.
Good luck, regards
