Method Detail

getTableCount

Map<String,Long> getTableCount()

Get the mapping containing {table name, row count} entries of the Activiti database schema.

getTableName

String getTableName(Class<?> activitiEntityClass)

Gets the table name (including any configured prefix) for an Activiti entity like Task, Execution or the like.

getTableMetaData

TableMetaData getTableMetaData(String tableName)

Gets the metadata (column names, column types, etc.) of a certain table. Returns null when no table exists with the given name.

createTablePageQuery

TablePageQuery createTablePageQuery()

Creates a TablePageQuery that can be used to fetch TablePage containing specific sections of table row data.

createJobQuery

JobQuery createJobQuery()

Returns a new JobQuery implementation, that can be used to dynamically query the jobs.

executeJob

void executeJob(String jobId)

Forced synchronous execution of a job (eg. for administation or testing) The job will be executed, even if the process definition and/or the process instance is in suspended state.

Parameters:

jobId - id of the job to execute, cannot be null.

Throws:

ActivitiObjectNotFoundException - when there is no job with the given id.

deleteJob

void deleteJob(String jobId)

Delete the job with the provided id.

Parameters:

jobId - id of the job to execute, cannot be null.

Throws:

ActivitiObjectNotFoundException - when there is no job with the given id.

setJobRetries

void setJobRetries(String jobId,
                 int retries)

Sets the number of retries that a job has left. Whenever the JobExecutor fails to execute a job, this value is decremented. When it hits zero, the job is supposed to be dead and not retried again. In that case, this method can be used to increase the number of retries.

Parameters:

jobId - id of the job to modify, cannot be null.

retries - number of retries.

getJobExceptionStacktrace

String getJobExceptionStacktrace(String jobId)

Returns the full stacktrace of the exception that occurs when the job with the given id was last executed. Returns null when the job has no exception stacktrace.

Parameters:

jobId - id of the job, cannot be null.

Throws:

ActivitiObjectNotFoundException - when no job exists with the given id.

getProperties

Map<String,String> getProperties()

get the list of properties.

databaseSchemaUpgrade

String databaseSchemaUpgrade(Connection connection,
                           String catalog,
                           String schema)

programmatic schema update on a given connection returning feedback about what happened

executeCommand

<T> T executeCommand(Command<T> command)

Executes a given command with the default CommandConfig.

Parameters:

command - the command, cannot be null.

Returns:

the result of command execution

executeCommand

<T> T executeCommand(CommandConfig config,
                   Command<T> command)

Executes a given command with the specified CommandConfig.

Parameters:

config - the command execution configuration, cannot be null.

command - the command, cannot be null.

Returns:

the result of command execution

executeCustomSql

<MapperType,ResultType> ResultType executeCustomSql(CustomSqlExecution<MapperType,ResultType> customSqlExecution)

[EXPERIMENTAL] Executes the sql contained in the CustomSqlExecution parameter.

getEventLogEntries

List<EventLogEntry> getEventLogEntries(Long startLogNr,
                                     Long pageSize)

[EXPERIMENTAL] Returns a list of event log entries, describing everything the engine has processed. Note that the event logging must specifically must be enabled in the process engine configuration. Passing null as arguments will effectively fetch ALL event log entries. Be careful, as this list might be huge!

getEventLogEntriesByProcessInstanceId

List<EventLogEntry> getEventLogEntriesByProcessInstanceId(String processInstanceId)

[EXPERIMENTAL] Returns a list of event log entries for a specific process instance id. Note that the event logging must specifically must be enabled in the process engine configuration. Passing null as arguments will effectively fetch ALL event log entries. Be careful, as this list might be huge!

deleteEventLogEntry

void deleteEventLogEntry(long logNr)

Delete a EventLogEntry. Typically only used in testing, as deleting log entries defeats the whole purpose of keeping a log.
