Syntax

public abstract class PerfTask : IDisposable

Remarks

Every performance task extends this class, and provides its own DoLogic() method, which performs the actual task.

Tasks performing some work that should be measured for the task, can override Setup() and/or TearDown() and place that work there.

Relevant properties:

• task.max.depth.log

Also supports the following logging attributes:

• log.step specifies how often to log messages about the current running task. Default is 1000 DoLogic() invocations. Set to -1 to disable logging.
• log.step.[class Task Name] specifies the same as 'log.step', only for a particular task name. For example, log.step.AddDoc will be applied only for AddDocTask. It's a way to control per task logging settings. If you want to omit logging for any other task, include log.step=-1. The syntax is "log.step." together with the Task's 'short' name (i.e., without the 'Task' part).

Parameters

Type	Name	Description

Returns

Type	Description

Parameters

Type	Name	Description
System.String	name	The name to set.

SetParams(String)

Set the params of this task.

Declaration

public virtual void SetParams(string params)

Parameters

Type	Name	Description
System.String	params

SetRunInBackground(Int32)

Declaration

public virtual void SetRunInBackground(int deltaPri)

Parameters

Type	Name	Description

Setup()

Task setup work that should not be measured for that specific task. By default it does nothing, but tasks can implement this, moving work from DoLogic() to this method. Only the work done in DoLogic() is measured for this task. Notice that higher level (sequence) tasks containing this task would then measure larger time than the sum of their contained tasks.

Declaration

public virtual void Setup()

StopNow()

Declaration

public virtual void StopNow()

TearDown()

Task teardown work that should not be measured for that specific task. By default it does nothing, but tasks can implement this, moving work from DoLogic() to this method. Only the work done in DoLogic() is measured for this task. Notice that higher level (sequence) tasks containing this task would then measure larger time than the sum of their
contained tasks.

Declaration

public virtual void TearDown()

ToString()

Declaration

public override string ToString()

Returns

Type	Description
System.String
