Kron

public class Kron : NSObject

Kron is a NSTimer manager offering 4 modes through a unified api. Kron takes care of the involved implementation of NSTimers while ensuring a proper memory management with no extra effort:

Kron.debounce: Calls immediatly and reject calls until time out elapses
Kron.debounceLast: As debounce but also performs the last call after time out
Kron.idle: Performs the last call after not being called during the timeout interval
Kron.watchdog: As idle but allowing to be canceled with watchDogCancel

Static Debouncer


                    
                    
                    debounceLast(timeOut:resetKey:context:action:)

Creates both a debounce and idle idle timer.

The function will debounce actions as defined in interval
Additionally will ensure to perform the last call after timeout
Timer will be reset if called again with the same KronKey

Declaration

    resetKey aKey:KronKey,
    context:Any? = nil,
    action:@escaping KronClosure)

Parameters

`interval`	the timeOut interval
`aKey`	an String or Class
`context`	any Struct or Class. (Internally wraped as a weak reference)
