/*!
|
@abstract Represents a request to the Facebook Graph API.
|
|
@discussion `FBSDKGraphRequest` encapsulates the components of a request (the
|
Graph API path, the parameters, error recovery behavior) and should be
|
used in conjunction with `FBSDKGraphRequestConnection` to issue the request.
|
|
Nearly all Graph APIs require an access token. Unless specified, the
|
`[FBSDKAccessToken currentAccessToken]` is used. Therefore, most requests
|
will require login first (see `FBSDKLoginManager` in FBSDKLoginKit.framework).
|
|
A `- start` method is provided for convenience for single requests.
|
|
By default, FBSDKGraphRequest will attempt to recover any errors returned from
|
Facebook. You can disable this via `disableErrorRecovery:`.

@discussion By default, non-batched FBSDKGraphRequest instances will automatically try to recover
|
from errors by constructing a `FBSDKGraphErrorRecoveryProcessor` instance that
|
re-issues the request on successful recoveries. The re-issued request will call the same
|
handler as the receiver but may occur with a different `FBSDKGraphRequestConnection` instance.
|
|
This will override [FBSDKSettings setGraphErrorRecoveryDisabled:].
