CacheDataDescriptor  - AS3 ADEP Data Services

The time in UTC that this cached data was first created in the local store. This value is set when autoSave is true is called and a fill(), getItem(), or createItem() request for data that is not already in the local store is completed; or saveCache() is called. Invocations of these methods when the data is already cached will change the last accessed time. The last updated time will also be updated if the cached data is updated as a result of the request.

The unique ID of the data cached. This is the value that the service uses to uniquely identify this data. For collections of items this is the value defined by the remote destination when a fill request is made. For single managed objects (SMOs) this is a map of name value pairs for the item as defined by the <identity> tag in the services-config.xml file.

The time in UTC that this cached data was last accessed from the local store. This value is set when a fill(), getItem(), or createItem() request for data that is not already in the local store is completed.

The time in UTC that this cached data was last filled from a remote server. Used to restore the fillTimestamp field of a dataList, which allows subsequent synchronizeFill() calls to know which changed data to retrieve from the server.

The time in UTC that this cached data was last written to the local store. This value is set when autoSave is true is called and a fill(), getItem(), or createItem() request for data that is not already in the local store is completed; or saveCache() is called. The last write time will be updated if the cached data is updated as a result of the request or a pushed update occurs when autoSave is true.

Provides access to custom information stored along with this data in the local store. Values assigned to this property must be serializable, that is, implement flash.util.IExternalizable or descend from no UI based objects. Typically this value is a string description of the data's relevance within the system. For example "All gold customers" or "All orders over $10K".

Verwante API-elementen

Contains true if this query was synced when it was requested from the server. A synced query is one for which the server pushes change notifications to the client. Therefore, a true value indicates an up to date, with respect to the server, query at the time of its persistence to the local store.

The type of data this cache descriptor is associated with. Valid values are:

• CacheDataDescriptor.FILL - descriptor is for a filled collection.
• CacheDataDescriptor.ITEM - descriptor is for a managed item.

Initializes this descriptor with the specified cache item and associated id.

Returns a String representation of the CacheDataDescriptor object.

Option for use with the getCacheDescriptors() method to indicate the type of descriptors to return. This constant indicates that descriptors for both filled collections and single managed objects should be returned.

Option for use with the getCacheDescriptors() method to indicate the type of descriptors to return. This constant indicates that only descriptors for filled collections should be returned. This constant is also used to indicate the value of a descriptor's type.
