Properties

CancellationToken

Gets the cancellation token.

Declaration

CancellationToken CancellationToken { get; }

Property Value

Type	Description
CancellationToken	The cancellation token.

Exception

Gets the exception if an exception occurred while executing the ExecutableWork.

Declaration

Exception Exception { get; }

Property Value

Type	Description
Exception	The exception.

Message

Gets the message.

Declaration

string Message { get; }

Property Value

Type	Description
System.String	The message.

Progress

Gets the progress as a fraction between 0 (no progress) and 1 (complete).

Declaration

double Progress { get; }

Property Value

Type	Description
System.Double	The progress as a fraction between 0 and 1.

Result

Gets the result.

Declaration

object Result { get; }

Property Value

Type	Description
System.Object	The result.

Status

Gets the work status.

Declaration

WorkStatus Status { get; }

Property Value

Type	Description
WorkStatus	The status.

Methods

Abort(String)

Aborts the work.

Declaration

void Abort(string message = null)

Parameters

Type	Name	Description
System.String	message	The message.

Complete(Object, String)

Completes the work.

Declaration

void Complete(object result, string message = null)

Parameters

Type	Name	Description
System.Object	result	The result.
System.String	message	The message.

Derive(IComputationalWork)

Derives a child context for a particular combination of work and input.

Declaration

IExecutionContext Derive(IComputationalWork work)

Parameters

Type	Name	Description
IComputationalWork	work	The work.

Returns

Type	Description
IExecutionContext	A child context.

Remarks

This is used when a composite IComputationalWork executes by executing each constituent part. In that case a dedicated context must be derived for each part.

Fail(String, Exception)

Report that the work failed.

Declaration

void Fail(string message, Exception e = null)

Parameters

Type	Name	Description
System.String	message	The message.
Exception	e	An optional exception, if caught.

UpdateProgress(Double, String)
