org.openstreetmap.josm.data.osm.DataSet
o something with dataset } finally { ds.getReadLock().unlock(); } Write lock should be used in case of bulk operations. In addition to ensuring that other threads can't use dataset in the middle of modifications it also stops sending of dataset events. That's good for performance reasons - GUI can be updated after all changes are done. Sample usage: ds.beginUpdate() try { // .. do modifications } finally { ds.endUpdate(); } Note that it is not necessary to call beginUpdate/endUpdate for every dataset modification - dataset will get locked automatically. Note that locks cannot be upgraded - if one threads use read lock and and then write lock, dead lock will occur - see #5814 for sample ticket @author imi
