/**
|
|
* FileSystem
|
|
*
|
|
* A FileSystem takes an `options` object, which can specify a number of,
|
|
* options. All options are optional, and include:
|
|
*
|
|
* name: the name of the file system, defaults to "local"
|
|
*
|
|
* flags: one or more flags to use when creating/opening the file system.
|
|
* For example: "FORMAT" will cause the file system to be formatted.
|
|
* No explicit flags are set by default.
|
|
*
|
|
* provider: an explicit storage provider to use for the file
|
|
* system's database context provider. A number of context
|
|
* providers are included (see /src/providers), and users
|
|
* can write one of their own and pass it in to be used.
|
|
* By default an IndexedDB provider is used.
|
|
*
|
|
* callback: a callback function to be executed when the file system becomes
|
|
* ready for use. Depending on the context provider used, this might
|
|
* be right away, or could take some time. The callback should expect
|
|
* an `error` argument, which will be null if everything worked. Also
|
|
* users should check the file system's `readyState` and `error`
|
|
* properties to make sure it is usable.
