For the given hook event, fetch the array of hook events and process them. Determine the proper callback for each hook and then call the actual hook using the appropriate arguments. Finally, process the return value and return/throw accordingly.

For hook event that are not abortable through a handler's return value, use runWithoutAbort() instead.

runner()

static Hooks::runner ( )

static

Since

1.35
