Package jline.lang.workflow

Class WorkflowActivity

java.lang.Object

jline.lang.Element

jline.lang.workflow.WorkflowActivity

All Implemented Interfaces:

Serializable, Copyable

public class WorkflowActivity
extends Element

A computational activity in a Workflow.

Unlike Activity in LayeredNetwork, it carries no call list: an external call is represented as an activity whose host demand is the law of the call response time, so that a synchronous call and a local computation compose in the same way. An asynchronous call blocks the caller for no time and is simply left out of the workflow.

WorkflowActivity

public WorkflowActivity(Workflow workflow,
 String name,
 Distribution hostDemand)

Method Details

setHostDemand

public void setHostDemand(double meanServiceTime)

setHostDemand

public void setHostDemand(Distribution hostDemand)

setHostDemandMean

public void setHostDemandMean(double meanValue)

Change the mean, preserving the shape.

Scales the current law in time rather than refitting it, so the SCV, the skewness and the order are preserved and the cached series-parallel tree keeps its shape.

Parameters:

meanValue - new mean, positive and finite

getHostDemand

public Distribution getHostDemand()

getHostDemandMean

public double getHostDemandMean()

getHostDemandSCV

public double getHostDemandSCV()

getWorkflow

public Workflow getWorkflow()

getIndex

public int getIndex()

setIndex

public void setIndex(int index)

getPHRepresentation

public Pair<Matrix,Matrix> getPHRepresentation()

getNumberOfPhases

public int getNumberOfPhases()

getMetadata

public Map<String,Object> getMetadata()

Get optional metadata (e.g., from WfCommons).

Returns:

Metadata map or null if not set

setMetadata

public void setMetadata(Map<String,Object> metadata)

Set optional metadata.

Parameters:

metadata - Metadata map

hasMetadata

public boolean hasMetadata()

Check if metadata is present.

Returns:

true if metadata is set

getMetadataValue

public Object getMetadataValue(String key)

Get a metadata value by key.

Parameters:

key - Metadata key

Returns:

Value or null if not present

setMetadataValue

public void setMetadataValue(String key,
 Object value)

Set a metadata value.

Parameters:

key - Metadata key

value - Metadata value
