Constructor.
addOfflineItem | () | method |
override public function addOfflineItem(item:Object):void
Language Version: | ActionScript 3.0 |
Product Version: | Adobe Digital Enterprise Platform Data Services for Java EE 3.1 |
Runtime Versions: | Flash Player 9, AIR 1.1 |
Adds the specified offline item to the localStore.
Parameters

Appends to the byte array the specified data items. Use this method to aggregate multiple data service (data manager) archives together.
Parameters
archiveData:IDataOutput — - the output stream to append to.
| |
version:String — - the version number to perform format mismatch checking with.
The intention is that this should change only when the data format changes.
| |
changedItems:ChangedItems — - describes the created, updated, and deleted items to be imported
into the local cache. Note that the timestamp and fillParameters must be specified,
to allow subsequent synchronizeFill() calls to work properly to match the imported

executeOfflineQuery | () | method |
override public function executeOfflineQuery(propSpecifier:PropertySpecifier, args:Array, startIndex:int, numItems:int):mx.rpc:AsyncToken
Language Version: | ActionScript 3.0 |
Product Version: | Adobe Digital Enterprise Platform Data Services for Java EE 3.1 |
Runtime Versions: | Flash Player 9, AIR 1.1 |
Used with SQLite adapters to execute dynamic queries locally.
The default implementation of this function will build a SQL statement for the query in the following manner:
- The SELECT clause will be based on the passed-in property specifier.
-
The WHERE clause will be determined by an invocation to
getQueryCriteria()
, which custom implementations should override to return the appropriate WHERE clause for a given set of fill parameters. - The LIMIT (range of selected items) clause will be determined by the start index and number of items arguments.
Once the whole SQL statement has been constructed, it is passed to
internalExecuteOfflineQuery
for execution.
Custom implementations should only override this method if they want to perform the full SQL statement creation process on their own.
Parameters
propSpecifier:PropertySpecifier — property specifier determines the SELECT clause for the query
| |
args:Array — fill arguments used by custom implementations to determine the WHERE clause for the query
| |
startIndex:int — start index for a paged query
| |
numItems:int — number of items to retrieve for a paged query or -1 to retrieve all.
|
mx.rpc:AsyncToken — AsyncToken with the result being an array of strongly typed items
|

OfflineAdapter implementations should override this method with an implementation that returns an appropriate SQL WHERE clause for a given set of fill parameters. The WHERE clause should conform to the schema generated for the offline store for the destination in context. The convention for this schema is that item-class property names are mapped one-to-one to the column names of their storage tables.
Note that the WHERE clause may refer only to columns of the table backing items for the destination in context.
This method is called by executeOfflineQuery
in order to determine
the WHERE clause to use for the query being executed.
Parameters
args:Array — fill parameters.
|
String — SQL WHERE clause for the corresponding fill parameters. Returns null if no WHERE
clause need be used for the corresponding fill paramters. Default implementation returns
null for all fill parameters.

OfflineAdapter implementation should override this method with an implementation
that returns the values used to substitute parameters in the WHERE clause from
getQueryCriteria

This method is called by the executeOfflineQuery()
method to determine
the substitutions that are required for the query being executed.
Parameters
args:Array — fill parameters.
|
Object — Object with key-value pairs. The keys represent the names of the parameters to
replace and the values correspond to the substitution values. Positional parameters
can be substituted using integer keys. Default implementation returns null.

OfflineAdapter implementations should override this method with an implementation that returns an appropriate SQL ORDER BY clause for a given set of fill parameters. The ORDER BY clause should conform to the schema generated for the offline store for the destination in context. The convention for this schema is that item-class property names are mapped one-to-one to the column names of their storage tables. Note that the ORDER BY clause can refer only to columns of the table backing items for the destination in context.
This method is called by the executeOfflineQuery()
method to determine
the ORDER BY clause to use for the query being executed.
Parameters
args:Array — fill parameters.
