Class SuiteStagesWrapper

      edu.sdsc.inca.util.SuiteStagesWrapper

public class SuiteStagesWrapper
extends XmlWrapper

Convenience object for accessing suite stages documents and persisting changes to them. A suite stages document stores series configs from a suite document in expanded form (i.e., macros are expanded and schedules selected). There are 3 main stages of a suite's series configs. 1) the series configs as specified by the user. These are known in the suite stages document as a "MultiResourceConfigs" meaning that each series config can potentially expand to run on multiple resources. 2) the expanded series configs per resource. These are known in the suite stages document as "PerResourceConfigs" meaning that the series config applies to a single resource.

Method Detail

chooseCronFieldValue

public static java.lang.String chooseCronFieldValue(java.lang.String field,
                                                    boolean startAtOne,
                                                    int count)
                                             throws ConfigurationException

Given a field in a cron line (e.g., hour or day), check it for instances of '?' meaning anytime. For example, '?' in the hour field would indicate to run at any hour of the day. Similarly, '?' in the minute field would indicate to run at any hour of the minute. '?-[max]/[number]' indicates to run every [number] seconds at any offset with an upper bound of max. For example, '?-23/8' in the hour field indicates to run every 8 hours beginning at any offset. In this latter example, this function could return ?=4-23/8 meaning run at hours 4,12, and 20.

Parameters:

field - The field from a cron line which may or may not contain '?'

startAtOne - True if the minimum value of the field is 1. Otherwise 0 is assumed. E.g., it would be false for minute and true for days.

count - The count for the field. E.g., 24 for hours, 60 for minutes, etc.

Returns:

A string where values are chose for the '?'. For, example '?=52' or '?=2-59/4'.

Throws:

ConfigurationException

chooseSchedule

public static edu.sdsc.inca.dataModel.util.Schedule chooseSchedule(edu.sdsc.inca.dataModel.util.Schedule schedule)
                                                            throws ConfigurationException

A schedule may contain '?' in its cron fields meaning run at any time in the field. E.g., ? ?/5 * * * means run every 5th hour at any minute in the day. The agent will resolve these '?' to concrete running times. In the example, the agent could decide to run on the 35th minute of the hour starting at hour 2 (i.e., 35 2-23/5 * * *). The agent will choose running times randomly.

Parameters:

schedule - A schedule that may or may not contain '?'

Returns:

A schedule with all instances of '?' resolved to concrete running times.

Throws:

ConfigurationException
