Callback
The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).
The callback for the getEntryIndex([callback]) method is defined as:
function(err, data){ }
'err' is the error that occurred. If there was no error, then 'err' is 'null'.
'data' is the value returned by the method.
The callback for the setEntryIndex([callback]) method is defined as:
function(err){ }
'err' is the error that occurred. If there was no error, then 'err' is 'null'.
'err' has 2 properties which hold detailed information:
err.code err.message
Remarks
This property is used to specify an entry within a retrieved Google Data feed. Once set, EntryETag will be set and EntryElements will be populated with each element found within the entry.
This property takes index values from 0 to EntryCount-1.
Setting EntryIndex to -1 will clear the entries contained by the component and will also reset EntryElements, EntryCount, and EntryETag.
This property is not available at design time.
