Functions Detail

ClearBoundDataStores Source code

native function ClearBoundDataStores ( )
Notifies this subscriber to unbind itself from all bound data stores

GetBoundDataStores Source code

native function GetBoundDataStores ( out array<UIDataStore> out_BoundDataStores )
Retrieves the list of data stores bound by this subscriber.
@param out_BoundDataStores receives the array of data stores that subscriber is bound to.

GetDataStoreBinding Source code

native const function string GetDataStoreBinding ( optional int BindingIndex=INDEX_NONE ) con )
Retrieves the markup string corresponding to the data store that this object is bound to.
@param BindingIndex optional parameter for indicating which data store binding is being requested for those objects which have multiple data store bindings. How this parameter is used is up to the class which implements this interface, but typically the "primary" data store will be index 0.
@return a datastore markup string which resolves to the datastore field that this object is bound to, in the format:

NotifyDataStoreValueUpdated Source code

native function NotifyDataStoreValueUpdated ( UIDataStore SourceDataStore, bool bValuesInvalidated, name PropertyTag, UIDataProvider SourceProvider, int ArrayIndex )
Handler for the UIDataStore.OnDataStoreValueUpdated delegate. Used by data stores to indicate that some data provided by the data has changed. Subscribers should use this function to refresh any data store values being displayed with the updated value. notify subscribers when they should refresh their values from this data store.
@param SourceDataStore the data store that generated the refresh notification; useful for subscribers with multiple data store bindings, to tell which data store sent the notification.
@param bValuesInvalidated TRUE if the data values were completely invalidated; suggest a full refresh rather than an update (i.e. in lists)
@param PropertyTag the tag associated with the data field that was updated; Subscribers can use this tag to determine whether there is any need to refresh their data values.
@param SourceProvider for data stores which contain nested providers, the provider that contains the data which changed.
@param ArrayIndex for collection fields, indicates which element was changed. value of INDEX_NONE indicates not an array or that the entire array was updated.

RefreshSubscriberValue Source code

native function bool RefreshSubscriberValue ( optional int BindingIndex=INDEX_NONE )
Resolves this subscriber's data store binding and updates the subscriber with the current value from the data store.
@param BindingIndex optional parameter for indicating which data store binding is being requested for those objects which have multiple data store bindings. How this parameter is used is up to the class which implements this interface, but typically the "primary" data store will be index 0.
@return TRUE if this subscriber successfully resolved and applied the updated value.

SetDataStoreBinding Source code

native function SetDataStoreBinding ( string MarkupText, optional int BindingIndex=INDEX_NONE )
Sets the data store binding for this object to the text specified.
@param MarkupText a markup string which resolves to data exposed by a data store. The expected format is:
@param BindingIndex optional parameter for indicating which data store binding is being requested for those objects which have multiple data store bindings. How this parameter is used is up to the class which implements this interface, but typically the "primary" data store will be index 0.
