Method Detail

getId

public String getId()

Specified by:

getId in interface LockedExternalTask

Returns:

the id of the task

getTopicName

public String getTopicName()

Specified by:

getTopicName in interface LockedExternalTask

Returns:

the name of the topic the task belongs to

getWorkerId

public String getWorkerId()

Specified by:

getWorkerId in interface LockedExternalTask

Returns:

the id of the worker that has locked the task

getLockExpirationTime

public Date getLockExpirationTime()

Specified by:

getLockExpirationTime in interface LockedExternalTask

Returns:

the absolute time at which the lock expires

getRetries

public Integer getRetries()

Specified by:

getRetries in interface LockedExternalTask

Returns:

the number of retries left. The number of retries is provided by a task client, therefore the initial value is null.

getErrorMessage

public String getErrorMessage()

Specified by:

getErrorMessage in interface LockedExternalTask

Returns:

the full error message submitted with the latest reported failure executing this task; null if no failure was reported previously or if no error message was submitted

getProcessInstanceId

public String getProcessInstanceId()

Specified by:

getProcessInstanceId in interface LockedExternalTask

Returns:

the id of the process instance the task exists in

getExecutionId

public String getExecutionId()

Specified by:

getExecutionId in interface LockedExternalTask

Returns:

the id of the execution that the task is assigned to

getActivityId

public String getActivityId()

Specified by:

getActivityId in interface LockedExternalTask

Returns:

the id of the activity for which the task is created

getActivityInstanceId

public String getActivityInstanceId()

Specified by:

getActivityInstanceId in interface LockedExternalTask

Returns:

the id of the activity instance in which context the task exists

getProcessDefinitionId

public String getProcessDefinitionId()

Specified by:

getProcessDefinitionId in interface LockedExternalTask

Returns:

the id of the process definition the task's activity belongs to

getProcessDefinitionKey

public String getProcessDefinitionKey()

Specified by:

getProcessDefinitionKey in interface LockedExternalTask

Returns:

the key of the process definition the task's activity belongs to

getTenantId

public String getTenantId()

Specified by:

getTenantId in interface LockedExternalTask

Returns:

the id of the tenant the task belongs to. Can be null if the task belongs to no single tenant.

getVariables

public org.camunda.bpm.engine.variable.VariableMap getVariables()

Specified by:

getVariables in interface LockedExternalTask

Returns:

a map of variables that contains an entry for every variable that was specified at fetching time, if such a variable exists in the task's ancestor execution hierarchy.

getErrorDetails

public String getErrorDetails()

Specified by:

getErrorDetails in interface LockedExternalTask

Returns:

error details submitted with the latest reported failure executing this task; null if no failure was reported previously or if no error details was submitted

getPriority

public long getPriority()

Description copied from interface: LockedExternalTask

Returns the priority of the locked external task. The default priority is 0.

Specified by:

getPriority in interface LockedExternalTask

Returns:

the priority of the external task

getBusinessKey

public String getBusinessKey()

Description copied from interface: LockedExternalTask

Returns the business key of the process instance the external task belongs to

the business key

fromEntity

public static LockedExternalTaskImpl fromEntity(ExternalTaskEntity externalTaskEntity,
                                List<String> variablesToFetch,

                                boolean deserializeVariables)

Construct representation of locked ExternalTask from corresponding entity. During mapping variables will be collected,during collection variables will not be deserialized and scope will not be set to local.

Parameters:

externalTaskEntity - - source persistent entity to use for fields

variablesToFetch - - list of variable names to fetch, if null then all variables will be fetched

isLocal - - if true only local variables will be collected

Returns:

object with all fields copied from the ExternalTaskEntity, error details fetched from the database and variables attached
