# Class BulkTaskFinalizedEventArgs<TId, TResult>

OptimaJet.Workflow.Core.Runtime.Bulk.BulkTaskFinalizedEventArgs<TId, TResult>

Provides event data for the BulkAggregateTask<TId, TResult>.OnTaskFinalized event.

Namespace: [OptimaJet.Workflow.Core.Runtime.Bulk](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Runtime.Bulk/)

```csharp
public class BulkTaskFinalizedEventArgs<TId, TResult> : EventArgs
```

## Type Hierarchy

-   [EventArgs](https://learn.microsoft.com/dotnet/api/system.eventargs)
    -   BulkTaskFinalizedEventArgs<TId, TResult> Current type

## Constructors

`public BulkTaskFinalizedEventArgs(Dictionary<TId, BulkTaskResult<TResult>> results, TId lastFinalizedTaskId)` 

Initializes a new instance of [BulkTaskFinalizedEventArgs<TId, TResult>](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Runtime.Bulk/BulkTaskFinalizedEventArgs-TId-TResult/).

### Parameters

| Name | Type | Description |
| --- | --- | --- |
| `results` | `Dictionary<TId, BulkTaskResult<TResult>>` | A dictionary containing intermediate results for all tasks being tracked. |
| `lastFinalizedTaskId` | `{TId}` | The identifier of the last completed task. |

## Properties

`public Dictionary<TId, BulkTaskResult<TResult>> Results { get; }` 

Gets the dictionary of task identifiers and their current [BulkTaskResult<TResult>](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Runtime.Bulk/BulkTaskResult-TResult/) values.

### Remarks

Values are initially [BulkTaskResult<TResult>.Empty](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Runtime.Bulk/BulkTaskResult-TResult/) for each task; as processing continues, results and states are updated. When a task transitions from [BulkTaskState.Created](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Runtime.Bulk/BulkTaskState/) to [BulkTaskState.Running](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Runtime.Bulk/BulkTaskState/), the result value is not replaced, by design, for performance reasons.

`public TId LastFinalizedTaskId { get; }` 

The identifier of the last finalized task.

`public BulkTaskResult<TResult> LastFinalizedTaskResult { get; }` 

Gets the [BulkTaskResult<TResult>](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Runtime.Bulk/BulkTaskResult-TResult/) of the task identified by [BulkTaskFinalizedEventArgs<TId, TResult>.LastFinalizedTaskId](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Runtime.Bulk/BulkTaskFinalizedEventArgs-TId-TResult/).

### Exceptions

| Type | Description |
| --- | --- |
| `KeyNotFoundException` | The [BulkTaskFinalizedEventArgs<TId, TResult>.LastFinalizedTaskId](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Runtime.Bulk/BulkTaskFinalizedEventArgs-TId-TResult/) key is missing from [BulkTaskFinalizedEventArgs<TId, TResult>.Results](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Runtime.Bulk/BulkTaskFinalizedEventArgs-TId-TResult/). |

`public int Count { get; }` 

Gets the total number of tracked tasks.

`public int NotRanCount { get; }` 

Gets the number of tasks currently in the [BulkTaskState.Created](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Runtime.Bulk/BulkTaskState/) state.

`public int CompletedCount { get; }` 

Gets the number of tasks currently in the [BulkTaskState.Completed](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Runtime.Bulk/BulkTaskState/) state.

`public int FailedCount { get; }` 

Gets the number of tasks currently in the [BulkTaskState.Failed](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Runtime.Bulk/BulkTaskState/) state.

`public int FinalizedCount { get; }` 

Gets the number of tasks in the finalized states: [BulkTaskState.Completed](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Runtime.Bulk/BulkTaskState/) or [BulkTaskState.Failed](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Runtime.Bulk/BulkTaskState/).

`public decimal Progress { get; }` 

Gets the proportion of tasks with finalized results ([BulkTaskFinalizedEventArgs<TId, TResult>.FinalizedCount](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Runtime.Bulk/BulkTaskFinalizedEventArgs-TId-TResult/)) out of all tasks ([BulkTaskFinalizedEventArgs<TId, TResult>.Count](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Runtime.Bulk/BulkTaskFinalizedEventArgs-TId-TResult/)).

### Exceptions

| Type | Description |
| --- | --- |
| `DivideByZeroException` | No tasks are present, so [BulkTaskFinalizedEventArgs<TId, TResult>.Count](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Runtime.Bulk/BulkTaskFinalizedEventArgs-TId-TResult/) is zero. |
