Constructor Detail

OrJoinManager

public OrJoinManager()

Method Detail

setProcessHelper

public void setProcessHelper(IProcessModelParser helper)

Defines process model helper

Parameters:

helper - model helper to provide process graph

addOrJoin

public void addOrJoin(Integer orJoinIndex)

Register an OR-join

Parameters:

orJoinIndex - index of the OR-join to register

setEdgeIndexes

public void setEdgeIndexes(Map<Graph.Edge,Integer> indexes)

Defines indexes for Edges (from process graph)

Parameters:

indexes - map of Edge to its index

setSimulator

public void setSimulator(BPSimulator bpSimulator)

init

public void init()

Initializes the component. Builds BitSets for all incoming flows for all OR-joins.

getWaitingActivityForOr

public Integer getWaitingActivityForOr(Integer orIndex,
                                       BitSet processState)

Returns the index of the activity for which an OR-join in waiting for.

Parameters:

orIndex - index of an OR-join

processState - current process state

Returns:

null if all good, do not wait for anything. Otherwise index of activity being waited for.

registerWaitingOrJoin

public void registerWaitingOrJoin(String activityInstanceId,
                                  Integer orIndex)

Registers an OR join to be waiting for some activity to be completed in the process state

Parameters:

activityInstanceId - in format ProcessActivity.getInstanceId()

orIndex - activity index of an OR join

updateWaitingOrJoins

public Integer[] updateWaitingOrJoins(int activityIndex,
                                      ProcessInstance processInstance)

Update global cache of activities that OR joins are waiting for

Parameters:

activityIndex - activity index

processInstance - process instance

Returns:

array of enabled OR join indexes

isOrJoinWaitingForActivity

public boolean isOrJoinWaitingForActivity(int activityIndex,
                                          String activityId)

Returns if OR-join is waiting for an activity to be completed.

Parameters:

activityIndex - index of an element to check if OR join is waiting for it.

activityId - unique index of an OR-join

Returns:

true if OR join is waiting for activityIndex, false otherwise
