public interface JobExecutor
agent.executor.class configuration setting.
Each agent only has one instance of a job executor, which means
that a job executor must be thread-safe and able to execute more than
one job at a time. It is not a good solution to put the
keyword on the
executeJob(SessionControl, Agent, Job, JobAgentSettings, Job.ExecutionTime)
method since it would limit the execution to one job at a time.
A job executor must provide a public no-argument constructor.

agent- The agent
executeJobvoid executeJob(SessionControl sc, Agent agent, Job job, JobAgentSettings settings, Job.ExecutionTime usedSlot)Execute the specified job. This method is called in a new thread created specifically for running that job. If the agent is shutting down it will send an interrupt signal to all job threads. It is up to the job executor to decide how to handle this. It may either decide to kill the job or let it continue as if nothing happened.
The job sent to this method has it's status set to
Job.Status.PREPARED. The implementation of this method must change the status to either
Job.Status.ERROR. If the status hasn't changed the job agent will set the status to signal an unknown error.
SessionControlwhere the owner of the job is logged in and the correct active project is set
agent- The agent that sent the request to execute the job
job- The job to execute
settings- The specific settings used for the plugin on this job agent or null if no settings has been specified
usedSlot- The slot that was used to execut the job
closevoid close()This method is called at when the agent is stopped or paused. No more execution requests will be sent to the current job executor, but running jobs should NOT be terminated due to this method beeing called.
