|
||
77 | * Web connections are inherently stateless. As a consequence
|
||
78 | * of this, the semantics of serializable transactions are not
|
||
79 | * preserved. To understand the issue, consider an update operation.
|
||
80 | * The client fetches a feature instance. The feature is then
|
||
81 | * modified on the client side, and submitted back to the database
|
||
82 | * via a Transaction request for update. Serializability is lost
|
||
83 | * since there is nothing to guarantee that while the feature was
|
||
84 | * being modified on the client side, another client did not come
|
||
85 | * along and update that same feature in the database.
|
||
86 | * One way to ensure serializability is to require that access to
|
||
87 | * data be done in a mutually exclusive manner; that is while one
|
||
88 | * transaction accesses a data item, no other transaction can modify
|
||
89 | * the same data item. This can be accomplished by using locks that
|
||
90 | * control access to the data.
|
||
91 | * The purpose of the LockFeature operation is to expose a long
|
||
92 | * term feature locking mechanism to ensure consistency. The lock
|
||
93 | * is considered long term because network latency would make
|
||
94 | * feature locks last relatively longer than native commercial
|
||
95 | * database locks.
|
||
96 | * The LockFeature operation is optional and does not need to be
|
||
97 | * implemented for a WFS implementation to conform to this
|
||
98 | * specification. If a WFS implements the LockFeature operation,
|
||
99 | * this fact must be advertised in the capabilities document
