\brief Interface to the global state of the QmlJS code model.
|
|
\sa QmlJS::Document QmlJS::Snapshot QmlJSTools::Internal::ModelManager
|
|
|
|
The ModelManagerInterface is an interface for global state and actions in
|
|
the QmlJS code model. It is implemented by \l{QmlJSTools::Internal::ModelManager}
|
|
and the instance can be accessed through ModelManagerInterface::instance().
|
|
|
|
One of its primary concerns is to keep the Snapshots it
|
|
maintains up to date by parsing documents and finding QML modules.
|
|
|
|
It has a Snapshot that contains only valid Documents,
|
|
accessible through ModelManagerInterface::snapshot() and a Snapshot with
|
|
potentially more recent, but invalid documents that is exposed through
|
|
ModelManagerInterface::newestSnapshot().
