protected void |
cacheInit()
Only used by cache implementations |
void |
destroy()
Invoked for each parent-row after the last row for this entity is processed. |
protected void |
firstInit(Context context)
first time init call. |
protected List<Map<String,Object>> |
getAllNonCachedRows()
Get all the rows from the the datasource for the given query. |
protected Map<String,Object> |
getFromRowCacheTransformed()
|
protected Map<String,Object> |
getIdCacheData(String query)
If the where clause is present the cache is sql Vs Map of key Vs List of Rows. |
protected Map<String,Object> |
getNext()
|
protected Map<String,Object> |
getSimpleCacheData(String query)
If where clause is not present the cache is a Map of query vs List of Rows. |
void |
init(Context context)
This method is called when it starts processing an entity. |
Map<String,Object> |
nextDeletedRowKey()
This is used during delta-import. |
Map<String,Object> |
nextModifiedParentRowKey()
This is used during delta-import. |
Map<String,Object> |
nextModifiedRowKey()
This is used for delta-import. |
Map<String,Object> |
nextRow()
For a simple implementation, this is the only method that the sub-class should implement. |
