> Summary: JobContext: The context available during an IJobHandler execution.
Namespace Tracon · Assembly Tracon.Abstractions.dll
The context available during an [IJobHandler](/api/tracon.ijobhandler/) execution.
```csharp
public sealed class JobContext
```
- Inheritance
- object ← JobContext
- Inherited Members
- object.GetType(), object.ToString(), object.Equals(object?), object.Equals(object?, object?), object.ReferenceEquals(object?, object?), object.GetHashCode()
## Remarks
The handler does not access [IJobStore](/api/tracon.ijobstore/) directly; this keeps
the handler focused only on execution logic and removes the need to set
up a fake store in a unit test. It carries no service provider either:
the handler is built by the container from its own per-execution scope, so
its dependencies arrive through its constructor.
## Constructors
### JobContext\(\)
```csharp
public JobContext()
```
## Properties
### IsCancelledAsync
Checks whether the job was cancelled by an external request
(`POST .../cancel`). The handler supports cooperative
cancellation by checking this between items.
```csharp
public required Func> IsCancelledAsync { get; init; }
```
#### Property Value
[Func](https://learn.microsoft.com/dotnet/api/system.func\-2)<[CancellationToken](https://learn.microsoft.com/dotnet/api/system.threading.cancellationtoken), [ValueTask](https://learn.microsoft.com/dotnet/api/system.threading.tasks.valuetask\-1)<[bool](https://learn.microsoft.com/dotnet/api/system.boolean)\>\>
#### Remarks
The built-in worker also cancels the handler's token within one
`TraconSchedulingOptions.PollInterval` of the cancel request, so a
handler that reads its token stops without asking. This check is the
immediate answer, read from the store.
### Items
The job's items, by sequence number. Carries every item, regardless of
[JobItemRecord.Status](/api/tracon.jobitemrecord/#Tracon_JobItemRecord_Status) — not filtered down to
[JobItemStatus.Pending](/api/tracon.jobitemstatus/) ones. On a retry (see
[IJobHandler.ExecuteAsync](/api/tracon.ijobhandler/#Tracon_IJobHandler_ExecuteAsync_Tracon_JobContext_System_Threading_CancellationToken_)'s remarks), items already
[JobItemStatus.Completed](/api/tracon.jobitemstatus/) or [JobItemStatus.Failed](/api/tracon.jobitemstatus/)
from an earlier attempt are present here too; the handler is
responsible for skipping them.
```csharp
public required IReadOnlyList Items { get; init; }
```
#### Property Value
[IReadOnlyList](https://learn.microsoft.com/dotnet/api/system.collections.generic.ireadonlylist\-1)<[JobItemRecord](/api/tracon.jobitemrecord/)\>
### Job
The record of the job being executed.
```csharp
public required JobRecord Job { get; init; }
```
#### Property Value
[JobRecord](/api/tracon.jobrecord/)
### ReportItemAsync
Reports an item's processing result. The handler must call this as
each item is processed; the result is reflected into the persistent
store and the job's counters.
```csharp
public required Func ReportItemAsync { get; init; }
```
#### Property Value
[Func](https://learn.microsoft.com/dotnet/api/system.func\-3)<[JobItemResult](/api/tracon.jobitemresult/), [CancellationToken](https://learn.microsoft.com/dotnet/api/system.threading.cancellationtoken), [ValueTask](https://learn.microsoft.com/dotnet/api/system.threading.tasks.valuetask)\>
