Applications can schedule tasks to run after interactions with the following:
Compare this to other scheduling alternatives:
The touch handling system considers one or more active touches to be an
'interaction' and will delay
runAfterInteractions() callbacks until all
touches have ended or been cancelled.
InteractionManager also allows applications to register animations by creating an interaction 'handle' on animation start, and clearing it upon completion:
runAfterInteractions takes either a plain callback function, or a
PromiseTask object with a
gen method that returns a
Promise. If a
PromiseTask is supplied, then it is fully resolved (including asynchronous
dependencies that also schedule more tasks via
starting on the next task that might have been queued up synchronously
By default, queued tasks are executed together in a loop in one
setImmediate batch. If
setDeadline is called with a positive number, then
tasks will only be executed until the deadline (in terms of js event loop run
time) approaches, at which point execution will yield via setTimeout,
allowing events such as touches to start interactions and block queued tasks
from executing, making apps more responsive.
Schedule a function to run after all interactions have completed. Returns a cancellable "promise".
Notify manager that an interaction has started.
Notify manager that an interaction has completed.
A positive number will use setTimeout to schedule any tasks after the eventLoopRunningTime hits the deadline value, otherwise all tasks will be executed in one setImmediate batch (default).
