# Invoker

`POST /predict/invoker`

Judge the type of referenceable information of next edit.

For previous edits, this model takes the latest one and then compares
it with earlier ones to determine the behavior (called an edit composition type) of the last edit, among
`rename`, `def&ref`, `clone` and `normal`.

If the last edit is a normal edit, this function will pass it to the locator and return predicted edit labels.
Otherwise, it will send the edit composition type to the front end.
