A Builder for a Constraints object.

Summary

Public constructors
`<init>()` A Builder for a `Constraints` object.

Public methods
Constraints.Builder	`addContentUriTrigger(@NonNull uri: Uri, triggerForDescendants: Boolean)` Sets whether the `WorkRequest` should run when a local `content:` `Uri` is updated.
Constraints	`build()` Generates the `Constraints` from this Builder.
Constraints.Builder	`setRequiredNetworkType(@NonNull networkType: NetworkType)` Sets whether device should have a particular `NetworkType` for the `WorkRequest` to run.
Constraints.Builder	`setRequiresBatteryNotLow(requiresBatteryNotLow: Boolean)` Sets whether device battery should be at an acceptable level for the `WorkRequest` to run.
Constraints.Builder	`setRequiresCharging(requiresCharging: Boolean)` Sets whether device should be charging for the `WorkRequest` to run.
Constraints.Builder	`setRequiresDeviceIdle(requiresDeviceIdle: Boolean)` Sets whether device should be idle for the `WorkRequest` to run.
Constraints.Builder	`setRequiresStorageNotLow(requiresStorageNotLow: Boolean)` Sets whether the device's available storage should be at an acceptable level for the `WorkRequest` to run.
Constraints.Builder	`setTriggerContentMaxDelay(duration: Long, @NonNull timeUnit: TimeUnit)` Sets the maximum delay that is allowed from the first time a `content:` `Uri` change is detected to the time when the `WorkRequest` is scheduled.
Constraints.Builder	`setTriggerContentMaxDelay(duration: Duration!)` Sets the maximum delay that is allowed from the first time a `content:` `Uri` change is detected to the time when the `WorkRequest` is scheduled.
Constraints.Builder	`setTriggerContentUpdateDelay(duration: Long, @NonNull timeUnit: TimeUnit)` Sets the delay that is allowed from the time a `content:` `Uri` change is detected to the time when the `WorkRequest` is scheduled.
Constraints.Builder	`setTriggerContentUpdateDelay(duration: Duration!)` Sets the delay that is allowed from the time a `content:` `Uri` change is detected to the time when the `WorkRequest` is scheduled.

Builder()

A Builder for a Constraints object.

Public methods

addContentUriTrigger

@NonNull fun addContentUriTrigger(
    @NonNull uri: Uri, 
    triggerForDescendants: Boolean
): Constraints.Builder

Sets whether the WorkRequest should run when a local content: Uri is updated. This functionality is identical to the one found in JobScheduler and is described in JobInfo.Builder#addTriggerContentUri(android.app.job.JobInfo.TriggerContentUri).

Parameters
`uri`	Uri: The local `content:` Uri to observe
`triggerForDescendants`	Boolean: `true` if any changes in descendants cause this `WorkRequest` to run

Return
`Constraints.Builder`	The current `Builder`

build

@NonNull fun build(): Constraints

Generates the Constraints from this Builder.

Return
`Constraints`	The `Constraints` specified by this Builder

setRequiredNetworkType

@NonNull fun setRequiredNetworkType(@NonNull networkType: NetworkType): Constraints.Builder

Sets whether device should have a particular NetworkType for the WorkRequest to run. The default value is NetworkType#NOT_REQUIRED.

Parameters
`networkType`	NetworkType: The type of network required for the work to run

Return
`Constraints.Builder`	The current `Builder`

setRequiresBatteryNotLow

@NonNull fun setRequiresBatteryNotLow(requiresBatteryNotLow: Boolean): Constraints.Builder

Sets whether device battery should be at an acceptable level for the WorkRequest to run. The default value is false.

Parameters
`requiresBatteryNotLow`	Boolean: `true` if the battery should be at an acceptable level for the work to run

Return
`Constraints.Builder`	The current `Builder`

setRequiresCharging

@NonNull fun setRequiresCharging(requiresCharging: Boolean): Constraints.Builder

Sets whether device should be charging for the WorkRequest to run. The default value is false.

Parameters
`requiresCharging`	Boolean: `true` if device must be charging for the work to run

Return
`Constraints.Builder`	The current `Builder`

setRequiresDeviceIdle

@NonNull fun setRequiresDeviceIdle(requiresDeviceIdle: Boolean): Constraints.Builder

Sets whether device should be idle for the WorkRequest to run. The default value is false.

Parameters
`requiresDeviceIdle`	Boolean: `true` if device must be idle for the work to run

Return
`Constraints.Builder`	The current `Builder`

setRequiresStorageNotLow

@NonNull fun setRequiresStorageNotLow(requiresStorageNotLow: Boolean): Constraints.Builder

Sets whether the device's available storage should be at an acceptable level for the WorkRequest to run. The default value is false.

Parameters
`requiresStorageNotLow`	Boolean: `true` if the available storage should not be below a a critical threshold for the work to run

Return
`Constraints.Builder`	The current `Builder`

setTriggerContentMaxDelay

@NonNull fun setTriggerContentMaxDelay(
    duration: Long, 
    @NonNull timeUnit: TimeUnit
): Constraints.Builder

Sets the maximum delay that is allowed from the first time a content: Uri change is detected to the time when the WorkRequest is scheduled. This functionality is identical to the one found in JobScheduler and is described in JobInfo.Builder#setTriggerContentMaxDelay(long).

Parameters
`duration`	Long: The length of the delay in `timeUnit` units
`timeUnit`	TimeUnit: The units of time for `duration`

Return
`Constraints.Builder`	The current `Builder`

setTriggerContentMaxDelay

@NonNull fun setTriggerContentMaxDelay(duration: Duration!): Constraints.Builder

Parameters
`duration`	Duration!: The length of the delay

Return
`Constraints.Builder`	The current `Builder`

setTriggerContentUpdateDelay

@NonNull fun setTriggerContentUpdateDelay(
    duration: Long, 
    @NonNull timeUnit: TimeUnit
): Constraints.Builder

Sets the delay that is allowed from the time a content: Uri change is detected to the time when the WorkRequest is scheduled. If there are more changes during this time, the delay will be reset to the start of the most recent change. This functionality is identical to the one found in JobScheduler and is described in JobInfo.Builder#setTriggerContentUpdateDelay(long).

Parameters
`duration`	Long: The length of the delay in `timeUnit` units
`timeUnit`	TimeUnit: The units of time for `duration`

Return
`Constraints.Builder`	The current `Builder`

setTriggerContentUpdateDelay

@NonNull fun setTriggerContentUpdateDelay(duration: Duration!): Constraints.Builder

Parameters
`duration`	Duration!: The length of the delay

Return
`Constraints.Builder`	The current `Builder`
