Constructor Detail

ConnectorExecutorImpl

public ConnectorExecutorImpl(int queueCapacity,
                     int corePoolSize,
                     org.bonitasoft.engine.log.technical.TechnicalLoggerService loggerService,
                     int maximumPoolSize,
                     long keepAliveTimeSeconds,
                     org.bonitasoft.engine.sessionaccessor.SessionAccessor sessionAccessor,
                     SessionService sessionService,
                     TimeTracker timeTracker)

The handling of threads relies on the JVM The rules to create new thread are: - If the number of threads is less than the corePoolSize, create a new Thread to run a new task. - If the number of threads is equal (or greater than) the corePoolSize, put the task into the queue. - If the queue is full, and the number of threads is less than the maxPoolSize, create a new thread to run tasks in. - If the queue is full, and the number of threads is greater than or equal to maxPoolSize, reject the task.

Parameters:

queueCapacity - The maximum number of execution of connector to queue for each thread

corePoolSize - the number of threads to keep in the pool, even if they are idle, unless allowCoreThreadTimeOut is set

loggerService -

timeout - if the execution of the connector is above this time in milliseconds the execution will fail

maximumPoolSize - the maximum number of threads to allow in the pool

keepAliveTime - when the number of threads is greater than the core, this is the maximum time that excess idle threads will wait for new tasks before terminating. (in seconds)
