Method Detail

newInstance

ElementInstance newInstance(long key,
                            ProcessInstanceRecord value,
                            ProcessInstanceIntent state)

newInstance

ElementInstance newInstance(ElementInstance parent,
                            long key,
                            ProcessInstanceRecord value,
                            ProcessInstanceIntent state)

removeInstance

void removeInstance(long key)

updateInstance

void updateInstance(ElementInstance scopeInstance)

updateInstance

void updateInstance(long key,
                    Consumer<ElementInstance> modifier)

setAwaitResultRequestMetadata

void setAwaitResultRequestMetadata(long processInstanceKey,
                                   AwaitProcessInstanceResultMetadata metadata)

incrementNumberOfTakenSequenceFlows

void incrementNumberOfTakenSequenceFlows(long flowScopeKey,
                                         org.agrona.DirectBuffer gatewayElementId,
                                         org.agrona.DirectBuffer sequenceFlowElementId)

Increments the number that counts how often the given sequence flow has been taken.

The number helps to determine if a parallel gateway can be activated or not. It should be incremented when one of the incoming sequence flows is taken.

Parameters:

flowScopeKey - the key of the flow scope that contains the gateway

gatewayElementId - the element id of the gateway that is the target of the sequence flow

sequenceFlowElementId - the element id of the sequence flow that is taken

decrementNumberOfTakenSequenceFlows

void decrementNumberOfTakenSequenceFlows(long flowScopeKey,
                                         org.agrona.DirectBuffer gatewayElementId)

Decrements the numbers that counts how often a sequence flow of the given gateway has been taken.

The number helps to determine if a parallel gateway can be activated or not. It should be decremented when the gateway is activated.

Parameters:

flowScopeKey - the key of the flow scope that contains the gateway

gatewayElementId - the element id of the gateway
