DeferredLevelDOWN |
|
================= |
|
|
|
**A mock LevelDOWN implementation that queues operations while a real LevelDOWN instance is being opened.** |
|

|
|
|
**DeferredLevelDOWN** implements the basic [AbstractLevelDOWN](https://github.com/rvagg/node-abstract-leveldown) API so it can be used as a drop-in replacement where LevelDOWN is needed. |
|
|
|
`put()`, `get()`, `del()` and `batch()` operations are all queued and kept in memory until a new LevelDOWN-compatible object can be supplied. |
|
|
|
The `setDb(db)` method is used to supply a new LevelDOWN object. Once received, all queued operations are replayed against that object, in order. |
|
|
|
`batch()` operations will all be replayed as the array form. Chained-batch operations are converted before being stored. |
