/**
|
||
|
|
* This module manages the bookkeeping when a component is in the process
|
||
|
|
* of being mounted or being unmounted. This is used as a way to enforce
|
||
|
|
* invariants (or warnings) when it is not recommended to call
|
||
|
|
* setState/forceUpdate.
|
||
|
|
*
|
||
|
|
* currentlyMountingInstance: During the construction phase, it is not possible
|
||
|
|
* to trigger an update since the instance is not fully mounted yet. However, we
|
||
|
|
* currently allow this as a convenience for mutating the initial state.
|
||
|
|
*
|
||
|
|
* currentlyUnmountingInstance: During the unmounting phase, the instance is
|
||
|
|
* still mounted and can therefore schedule an update. However, this is not
|
||
|
|
* recommended and probably an error since it's about to be unmounted.
|
||
|
|
* Therefore we still want to trigger in an error for that case.
