Package dev.inmo.krontab

Types

This interface was created for abstraction of next operation. Currently, there is only dev.inmo.krontab.internal.CronDateTimeScheduler realisation of this interface inside of this library, but you it is possible to create your own realisation of this interface for scheduling, for example, depending of users activity or something like this

KronSchedulerTz

interface KronSchedulerTz : KronScheduler

This interface extending KronScheduler to use DateTimeTz with taking into account offset of incoming time for next operation.

KronSchedulerWork

abstract class KronSchedulerWork(context: Context, workerParams: WorkerParameters) : CoroutineWorker

Use this class as a super class in case you wish to implement krontab-based enqueuing of works

KrontabTemplate

typealias KrontabTemplate = String

KrontabTemplateSchedulerWork

abstract class KrontabTemplateSchedulerWork(context: Context, workerParams: WorkerParameters) : KronSchedulerWork

Extend this class in case you wish to base on KrontabTemplate. It will automatically handle request of kronScheduler and put it in setUpRequest

KrontabTemplateWrapper

data class KrontabTemplateWrapper(val template: KrontabTemplate) : KronScheduler

This class contains template and can be simply serialized/deserialized. In fact that class will work as dev.inmo.krontab.internal.CronDateTimeScheduler due to the fact that toKronScheduler will return it under the hood

LambdaKronScheduler

class LambdaKronScheduler(onNext: suspend (<ERROR CLASS>) -> <ERROR CLASS>?) : KronScheduler

LambdaKronSchedulerTz

class LambdaKronSchedulerTz(onNext: suspend (<ERROR CLASS>) -> <ERROR CLASS>?) : KronSchedulerTz

Functions

buildSchedule

fun buildSchedule(incoming: KrontabTemplate): KronScheduler

fun buildSchedule(incoming: KrontabTemplate, defaultOffset: Minutes): KronSchedulerTz

Shortcut for createSimpleScheduler

createSimpleScheduler

fun createSimpleScheduler(incoming: KrontabTemplate): KronScheduler

Parse incoming string and adapt according to next format: "* * * * *" where order of things:

fun createSimpleScheduler(incoming: KrontabTemplate, defaultOffset: Minutes): KronSchedulerTz

doInfinity

inline suspend fun KronScheduler.doInfinity(noinline block: suspend (<ERROR CLASS>) -> Unit)

Will execute block without any checking of result

inline suspend fun doInfinity(scheduleConfig: String, noinline block: suspend (<ERROR CLASS>) -> Unit)

Will buildSchedule using scheduleConfig and call doInfinity with block

doInfinityTz

inline suspend fun KronScheduler.doInfinityTz(noinline block: suspend (<ERROR CLASS>) -> Unit)

Will execute block without any checking of result

inline suspend fun doInfinityTz(scheduleConfig: String, noinline block: suspend (<ERROR CLASS>) -> Unit)

Will buildSchedule using scheduleConfig and call doInfinity with block

doOnce

inline suspend fun <T> KronScheduler.doOnce(noinline block: suspend (<ERROR CLASS>) -> T): T

Execute block once at the KronScheduler.next time and return result of block calculation.

inline suspend fun <T> doOnce(scheduleConfig: String, noinline block: suspend (<ERROR CLASS>) -> T): T

Will buildSchedule using scheduleConfig and call doOnce on it

doOnceTz

inline suspend fun <T> KronScheduler.doOnceTz(noinline block: suspend (<ERROR CLASS>) -> T): T

Execute block once at the KronScheduler.next time and return result of block calculation.

inline suspend fun <T> doOnceTz(scheduleConfig: String, noinline block: suspend (<ERROR CLASS>) -> T): T

Will buildSchedule using scheduleConfig and call doOnce on it

doWhile

inline suspend fun KronScheduler.doWhile(noinline block: suspend (<ERROR CLASS>) -> Boolean)

Will execute block while it will return true as a result of its calculation

inline suspend fun doWhile(scheduleConfig: String, noinline block: suspend (<ERROR CLASS>) -> Boolean)

Will buildSchedule using scheduleConfig and call doWhile with block

doWhileTz

inline suspend fun KronScheduler.doWhileTz(noinline block: suspend (<ERROR CLASS>) -> Boolean)

Will execute block while it will return true as a result of its calculation

inline suspend fun doWhileTz(scheduleConfig: String, noinline block: suspend (<ERROR CLASS>) -> Boolean)

Will buildSchedule using scheduleConfig and call doWhile with block

enqueueKronSchedulerWork

inline suspend fun <T : KronSchedulerWork> Context.enqueueKronSchedulerWork( workName: String, initialScheduler: KronScheduler, existingWorkPolicy: ExistingWorkPolicy = ExistingWorkPolicy.REPLACE, noinline setUpRequest: suspend OneTimeWorkRequest.Builder.() -> Unit = {}): Operation?

This method is shortcut for enqueueKronSchedulerWork with reified T

inline suspend fun <T : KronSchedulerWork> Context.enqueueKronSchedulerWork( workName: String, delayMillis: Long, existingWorkPolicy: ExistingWorkPolicy = ExistingWorkPolicy.REPLACE, noinline setUpRequest: suspend OneTimeWorkRequest.Builder.() -> Unit = {}): Operation

This method is shortcut for enqueueKronSchedulerWork with reified T parameter

suspend fun <T : KronSchedulerWork> Context.enqueueKronSchedulerWork( workName: String, initialScheduler: KronScheduler, workClass: Class<T>, existingWorkPolicy: ExistingWorkPolicy = ExistingWorkPolicy.REPLACE, setUpRequest: suspend OneTimeWorkRequest.Builder.() -> Unit = {}): Operation?

This method is shortcut for enqueueKronSchedulerWork with initialScheduler. It will try to calculate delay by itself. In case if KronScheduler.next of initialScheduler will return null, work WILL NOT be enqueued

suspend fun <T : KronSchedulerWork> Context.enqueueKronSchedulerWork( workName: String, delayMillis: Long, workClass: Class<T>, existingWorkPolicy: ExistingWorkPolicy = ExistingWorkPolicy.REPLACE, setUpRequest: suspend OneTimeWorkRequest.Builder.() -> Unit = {}): Operation

This method will enqueue OneTimeWorkRequest with workName and existingWorkPolicy. Use setUpRequest callback in case you need some additional actions to do before request will be enqueued

enqueueKrontabTemplateSchedulerWork

inline suspend fun <T : KrontabTemplateSchedulerWork> Context.enqueueKrontabTemplateSchedulerWork( workName: String, krontabTemplate: KrontabTemplate, existingWorkPolicy: ExistingWorkPolicy = ExistingWorkPolicy.REPLACE, noinline setUpRequest: suspend OneTimeWorkRequest.Builder.(data: Data) -> Unit = {}): Operation?

Will enqueueKronSchedulerWork with KronScheduler from krontabTemplate and call setUpRequest on setting up OneTimeWorkRequest.Builder with Data which will be used to OneTimeWorkRequest.Builder.setInputData after setUpRequest completed
