Represents a lock set on a Packflow object by a user.
This lock prevents other users to modify the concerned object at the same time, avoiding conflicts.
Note: this does NOT prevent object modification using the API.

The PFObjectLock type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | PFObjectLock |
Properties| Name | Description | |
|---|---|---|
 | BeforeSaveValues |
Gets the previous values of modified fields before the latest Save.
(Inherited from PFBaseObject.)Note: this feature is NOT persisted in the database and therefore only concerns this instance. |
| CanDelete |
Checks if the current permission context allows current user to delete this object.
(Inherited from PFBaseObject.) |
| CanRead |
Checks if the current permission context allows current user to access this object.
(Inherited from PFBaseObject.) |
| CanUpdate |
Checks if the current permission context allows current user to update this object.
(Inherited from PFBaseObject.) |
| Created |
Indicates if this object has been created and is still in database (positive Id).
(Inherited from PFBaseObject.) |
| CreatedAt |
Gets the date of creation of this object in the database.
(Inherited from PFBaseObject.) |
| CreatedBy |
Gets the user who created this object in the database.
(Inherited from PFBaseObject.) |
| Data |
Gets the data collection of this object.
(Inherited from PFBaseObject.) |
| DateObjectCreation |
Gets the date of the creation of this object in memory.
(Inherited from PFManagedObject.) |
| Deleted |
True if this object is flagged as deleted.
(Inherited from PFBaseObject.) |
| DeletedAt |
Date of the suppression of this object.
(Inherited from PFBaseObject.) |
| DeletedBy |
The user who deleted this object.
(Inherited from PFBaseObject.) |
| DisplayText |
Gets or sets the display text representing the locked object.
|
| EnableVersionMergeToResolveSaveConflicts |
Gets a value indicating whether versions can be merged to resolve save conflicts.
If an object is saved with an older version than the last persisted (in database),
the system will try to merge the versions values (if no conflicts between values)
and will then save the merged item to database.
Note : this setting is NOT persisted and will affect this object instance only.
(Inherited from PFBaseObject.) |
| Exists |
Indicates if this object has been created, still exists in database and is not flagged for suppression.
(Inherited from PFBaseObject.) |
| ExpirationDate |
Gets the expiration date. By default,
the date is set to the object creation time + DefaultValidity (900 seconds).
You can reset this date using the ResetValidity method. |
| Expired |
Gets a value indicating whether the expiration date is passed.
|
| Guid |
Gets the GUID identifying this object.
Must be used if Id is no more viable, example if content were merged.
(Inherited from PFBaseObject.) |
| HasPendingModifications |
Checks if there is pending changes.
Will check if the values are different from the currently persisted values.
(Inherited from PFBaseObject.) |
| HasPendingPermissionsModifications |
Checks if there is pending modifications in permissions.
Will compute permissions (RUD) and check if there is differences with current persisted permissions.
(Inherited from PFBaseObject.) |
| Id |
Gets the id identifying this object.
Must be used to find or identify an object because faster than Guid.
(Inherited from PFBaseObject.) |
| KeepBeforeSaveValues |
Gets or sets a value indicating whether
the Save should keep a collection of the modified fields previous values.
(Inherited from PFBaseObject.)Note: this feature is NOT persisted in the database and therefore only concerns this instance. |
| Logger |
Gets the logger, used to log any useful warning, error or information in the database.
(Inherited from PFManagedObject.) |

If the object has not been previously loaded, it is loaded from the object reference. |
| ObjectGuid |
Gets the locked object GUID.
|
| ObjectReference |
Gets the locked object reference.

Gets the root of the persisted objects tree.

Gets or sets a value indicating whether the lock also provides unlimited modification to the user.
E.g. in this mode the user can modify all fields, ignoring the current state rules. |
| UpdatedAt |
Gets the date of the last update of this object.
(Inherited from PFBaseObject.) |
| UpdatedBy |
Gets the user who last updated this object in the database.

|
| UserGuid |
Gets the GUID of the user owning this lock.
|
| UserId |
Gets the id of the user owning this lock.
|
| VersionNumber |
