Method Detail

registered

protected void registered(RequestServer.API_VERSION ver)

Description copied from class: Request2

Iterates over fields and their annotations, and creates argument handlers.

Overrides:

registered in class Job.ModelJob

queryArgumentValueSet

protected void queryArgumentValueSet(RequestArguments.Argument arg,
                         java.util.Properties inputArgs)

Description copied from class: RequestQueries

                    java.lang.String content)

Return the query link to this page

progress

public float progress()

Overrides:

progress in class Job

exec

public Job.JobState exec()

Description copied from class: Job

Actual job code.

Overrides:

exec in class Job

Returns:

true if job is done, false if it will still be running after the method returns.

redirect

protected RequestBuilders.Response redirect()

Overrides:

redirect in class Job
