|

64 | * DataSet is the data behind the application. It can consists of only a few points up to the whole
|
---|
65 | * osm database. DataSet's can be merged together, saved, (up/down/disk)loaded etc.
|
---|
66 | *
|
---|
67 | * Note that DataSet is not an osm-primitive and so has no key association but a few members to
|
---|
68 | * store some information.
|
---|
69 | *
|
---|
70 | * Dataset is threadsafe - accessing Dataset simultaneously from different threads should never
|
---|
71 | * lead to data corruption or ConcurrentModificationException. However when for example one thread
|
---|
72 | * removes primitive and other thread try to add another primitive referring to the removed primitive,
|
---|
73 | * DataIntegrityException will occur.
|
---|
74 | *
|
---|
75 | * To prevent such situations, read/write lock is provided. While read lock is used, it's guaranteed that
|
---|
76 | * Dataset will not change. Sample usage:
|
---|
77 | * <code>
|
---|
78 | * ds.getReadLock().lock();
|
---|
79 | * try {
|
---|
80 | * // .. do something with dataset
|
---|
81 | * } finally {
|
---|
82 | * ds.getReadLock().unlock();
|
---|
83 | * }
|
---|
84 | * </code>
|
---|
85 | *
|
---|
86 | * Write lock should be used in case of bulk operations. In addition to ensuring that other threads can't
|
---|
87 | * use dataset in the middle of modifications it also stops sending of dataset events. That's good for performance
|
---|
88 | * reasons - GUI can be updated after all changes are done.
|
---|
89 | * Sample usage:
|
---|
90 | * <code>
|
---|
91 | * ds.beginUpdate()
|
---|
92 | * try {
|
---|
93 | * // .. do modifications
|
---|
94 | * } finally {
|
---|
95 | * ds.endUpdate();
|
---|
96 | * }
|
---|
97 | * </code>
|
---|
98 | *
|
---|
99 | * Note that it is not necessary to call beginUpdate/endUpdate for every dataset modification - dataset will get locked
|
---|
100 | * automatically.
|
---|
101 | *
|
---|
102 | * Note that locks cannot be upgraded - if one threads use read lock and and then write lock, dead lock will occur - see #5814 for
|
---|
103 | * sample ticket
|
---|
