### <a name="getReadyQuery"></a>getReadyQuery(storeName)&nbsp;&nbsp;<sub><i>undefined</i></sub> ###

*This method is private*

__Arguments__

* __storeName__ *{string}*  

 The name of the store to observe



Returns a selector that will be used to identify files that
have been uploaded but have not yet been stored to the
specified store.

{
$where: "this.chunkSum === this.chunkCount",
'copies.storeName`: null,
'failures.copies.storeName.doneTrying': {$ne: true}
}

> ```function getReadyQuery(storeName) { ...``` [fileWorker.js:83](fileWorker.js#L83)


-

### <a name="getDoneQuery"></a>getDoneQuery(stores)&nbsp;&nbsp;<sub><i>undefined</i></sub> ###

*This method is private*

__Arguments__

* __stores__ *{Object}*  

 The stores object from the FS.Collection options



Returns a selector that will be used to identify files where all
stores have successfully save or have failed the
max number of times but still have chunks. The resulting selector
should be something like this:

{
$and: [
{chunks: {$exists: true}},
{
$or: [
{
$and: [
{
'copies.storeName': {$ne: null}
},
{
'copies.storeName': {$ne: false}
}
]
},
{
'failures.copies.storeName.doneTrying': true
}
]
},
REPEATED FOR EACH STORE
]

### <a name="saveCopy"></a>saveCopy(fsFile, storeName, options)&nbsp;&nbsp;<sub><i>Server</i></sub> ###

*This method is private*

     Force save to the specified store?


__Returns__  *{undefined}*


Saves to the specified store. If the
`overwrite` option is `true`, will save to the store even if we already
have, potentially overwriting any previously saved data. Synchronous.
