DbProcessState

public DbProcessState(ZeebeDb<ZbColumnFamilies> zeebeDb,
 TransactionContext transactionContext,
 EngineConfiguration config)

Method Details

putDeployment

public void putDeployment(DeploymentRecord deploymentRecord)

Specified by:

putDeployment in interface MutableProcessState

putLatestVersionDigest

public void putLatestVersionDigest(ProcessRecord processRecord)

Specified by:

putLatestVersionDigest in interface MutableProcessState

putProcess

public void putProcess(long key,
 ProcessRecord processRecord)

Specified by:

putProcess in interface MutableProcessState

updateProcessState

public void updateProcessState(ProcessRecord processRecord,
 PersistedProcess.PersistedProcessState state)

Description copied from interface: MutableProcessState

Updates the state of a process. This method updates both the ColumnFamily and the in memory cache.

Specified by:

updateProcessState in interface MutableProcessState

Parameters:

processRecord - the record of the process that is updated

state - the new state

deleteProcess

public void deleteProcess(ProcessRecord processRecord)

Description copied from interface: MutableProcessState

Deletes a process fromm the state and cache

Specified by:

deleteProcess in interface MutableProcessState

Parameters:

processRecord - the record of the process that is deleted

getLatestProcessVersionByProcessId

public DeployedProcess getLatestProcessVersionByProcessId(org.agrona.DirectBuffer processIdBuffer,
 String tenantId)

Specified by:

getLatestProcessVersionByProcessId in interface ProcessState

getProcessByProcessIdAndVersion

public DeployedProcess getProcessByProcessIdAndVersion(org.agrona.DirectBuffer processId,
 int version,
 String tenantId)

Specified by:

getProcessByProcessIdAndVersion in interface ProcessState

getProcessByKeyAndTenant

public DeployedProcess getProcessByKeyAndTenant(long key,
 String tenantId)

Specified by:

getProcessByKeyAndTenant in interface ProcessState

getLatestVersionDigest

public org.agrona.DirectBuffer getLatestVersionDigest(org.agrona.DirectBuffer processIdBuffer,
 String tenantId)

Specified by:

getLatestVersionDigest in interface ProcessState

getLatestProcessVersion

public int getLatestProcessVersion(String bpmnProcessId,
 String tenantId)

Description copied from interface: ProcessState

Gets the latest process version. This is the latest version for which we have a process in the state. It is not necessarily the latest version we've ever known for this process id, as process could be deleted.

Specified by:

getLatestProcessVersion in interface ProcessState

Parameters:

bpmnProcessId - the id of the process

getNextProcessVersion

public int getNextProcessVersion(String bpmnProcessId,
 String tenantId)

Description copied from interface: ProcessState

Gets the next version a process of a given id will receive. This is used, for example, when a new deployment is done. Using this method we decide the version the newly deployed process receives.

Specified by:

getNextProcessVersion in interface ProcessState

Parameters:

bpmnProcessId - the id of the process

findProcessVersionBefore

public Optional<Integer> findProcessVersionBefore(String bpmnProcessId,
 long version,
 String tenantId)

Description copied from interface: ProcessState

Finds the previous known version a process. This is used, for example, when a process is deleted and the timers of the previous process need to be activated.

If not previous version is found, an empty optional is returned.

Specified by:

findProcessVersionBefore in interface ProcessState

Parameters:

bpmnProcessId - the id of the process

version - the version for which we want to find the previous version

getFlowElement

public <T extends ExecutableFlowElement> T getFlowElement(long processDefinitionKey,
 String tenantId,
 org.agrona.DirectBuffer elementId,
 Class<T> elementType)

Specified by:

getFlowElement in interface ProcessState

clearCache

public void clearCache()

Description copied from interface: ProcessState

TODO: Remove the cache entirely from the immutable state

Specified by:

clearCache in interface ProcessState
