All Implemented Interfaces:

EnterpriseConfigurationObject

public class ScheduleConfig

extends EnterpriseConfigurationObjectImpl

implements EnterpriseConfigurationObject

A ScheduleConfig is a wrapper class that takes information stored in an OpenEAI Deployment document (Schedule Element) and stores it in a Java object. Then the configuration object is passed to the constructor of the OpenEAI Schedule objects and they are able to configure themselves with the information found in the config object.

Configuration Parameters:

These are the configuration parameters specified by the Schedule Element in the Deployment document. NOTE: Like all other OpenEAI configuration objects, there is a "container" level associated to Schedule elements. Many Elements and attributes are required at the container level and may be optionally overridden at this level. This is to avoid having to enter redundant information in the Deployment document if all (or most) Schedule objects being configured should use the same configuration information. Therefore, many of the Schedule configuration parameters are optional at this level but required at the "container" level. Where this is the case, it will be indicated by an "*".

Name	Required	Description
name	yes	Name of the Schedule being configured. This should be unique.
isImmediate (true | false)	no*	This flag indicates weather or not the ScheduledCommands associated to this Schedule should be executed immediately when the ScheduledApp awakes from its sleepInterval rather than using a "RunTime" to determine when the Schedule should be processed. If this is true, when the ScheduledApp wakes up, it will execute all ScheduledCommands associated to this Schedule. If it is false, the ScheduledApp will determine when/if the ScheduledCommands associated to this Schedule should be executed based on the Runtime associated to the Schedule.
runMechanism (Thread | SubProcess)	no*	This parameter indicates how the ScheduledCommands associated to this Schedule should be executed. If "Thread" is specified, the ScheduledCommands will be executed by adding them to the ThreadPool associated to the ScheduledApp. NOTE: Currently, only a runMechansim of "Thread" is supported. In the future, if "SubProcess" is specified a new VM will be started and the ScheduledCommand will be executed in that SubProcess.
ObjectClass	yes	Name of the Java object that will be instantiated with this Config class (currently, org.openeai.afa.Schedule)
RunTime	no	If the 'isImmediate' parameter is false, this Element specifies on what day(s) and at what time(s) the ScheduledCommands associated to this Schedule should be executed. If isImmediate is true, this information is ignored. Days are specified as follows: Daily (7 days a week) Weekdays (Monday thru Friday) Weekends (Saturday and Sunday) Sunday Monday Tuesday Wednesday Thursday Friday Saturday Times are specified as the Hour and Minute of the Day that the ScheduledCommands associated to the Schedule should be executed. It is possible to specify that a particular Schedule should be executed at multiple times within a given day.
Commands	yes	Provides configuration information for the ScheduledCommands associated to this Schedule. The ScheduledCommands use these CommandConfig objects to initialize themselves so they're ready to be executed when this Schedule is met.

Constructor Detail

ScheduleConfig

public ScheduleConfig()

This is the constructor used by AppConfig to instantiate the config object. Then, AppConfig calls this object's init(Element) method passing the configuration element it retrieved from the XML configuration document which this object uses to configure itself. After this object has initialized itself, it will be used to instantiate and initialize the framework object (MessageObject, Producers, Consumers, ThreadPools etc.) with the properties it's been initialized with.

ScheduleConfig

public ScheduleConfig(org.jdom.Element configElement)
               throws EnterpriseConfigurationObjectException

Method Detail

setDefaultParms

public void setDefaultParms(org.jdom.Element eDefaultParms)

Sets the default paramaters associated to this Schedule as specified in the "Schedules" Configuration Element (the container) in the application's config document.

These default parameters are built from the "container" level configuration component in the config document (Schedules). This is to allow "default" configuration information to be specified for all Schedules that exist within this container. If needed a particular Schedule can override these default parameters. Otherwise the default parameters are used. This way, duplicate configuration information does not have to be specified for each Schedule.

getDefaultParms

public org.jdom.Element getDefaultParms()

Returns the default paramaters associated to this Schedule as specified in the "Schedules" Configuration Element (the container) in the application's config document.

These default parameters are built from the "container" level configuration component in the config document (Schedules). This is to allow "default" configuration information to be specified for all Schedules that exist within this container. If needed a particular Schedule can override these default parameters. Otherwise the default parameters are used. This way, duplicate configuration information does not have to be specified for each Schedule.

Returns:

Element

setName

public void setName(java.lang.String name)

This method sets the name that will be associated to the Schedule as specified in the deployment document.

Overrides:

setName in class EnterpriseConfigurationObjectImpl

getName

public java.lang.String getName()

This method returns the name that will be associated to the Schedule as specified in the deployment document.

Overrides:

getName in class EnterpriseConfigurationObjectImpl

Returns:

String the Schedule's name.

setClassName

public void setClassName(java.lang.String className)

Ths method sets the class name that will be the Schedule implementation. Generally, this will be org.openeai.afa.Schedule. However, by allowing the flexibility of specifying the Schedule implementation, organizations could develop a different implementation of a Schedule that behaves differently if necessary.

getClassName

public java.lang.String getClassName()

Ths method returns the class name that will be the Schedule implementation. Generally, this will be org.openeai.afa.Schedule. However, by allowing the flexibility of specifying the Schedule implementation, organizations could develop a different implementation of a Schedule that behaves differently if necessary.

Returns:

String the class name of the Schedule implementation.

getCommandConfigs

public java.util.HashMap getCommandConfigs()

This method returns a list of all CommandConfig objects associated to this Schedule. These configuration objects will be used to initialize the actual ScheduledCommands that this Schedule must execute when the Schedule is met.

Returns:

HashMap

Schedule, ScheduledCommand

addCommandConfig

public void addCommandConfig(java.lang.String name,
                             CommandConfig cConfig)

This method adds a ScheduledCommand's configuration object to the list of CommandConfigs that this Schedule needs to initialize all the ScheduledCommands that it must execute. This method is called as the ScheduleConfig object reads through the deployment document and retrieves configuration information.

ScheduledCommand, CommandConfig, Schedule

getCommandConfig

public CommandConfig getCommandConfig(java.lang.String name)

Returns a CommandConfig object for the specified ScheduledCommand name.

Returns:

CommandConfig

getScheduleRuntimes

public java.util.ArrayList getScheduleRuntimes()

Returns the list of ScheduleRuntime objects that will be associated to the Schedule being configured with this configuration object.

Returns:

ArrayList

See Also:

Schedule, ScheduleRuntime

isImmediate

public boolean isImmediate()

Returns a flag indicating whether or not the Schedule being configured will be an "immediate" schedule.

Returns:

boolean

Schedule

init

public void init(org.jdom.Element configElement)
          throws EnterpriseConfigurationObjectException

Implements the init(Element) method that all EnterpriseConfiguration objects must implement. This init method takes the Configuration element passed in and pulls out configuration information specific to the Schedule being initialized. Then it sets various instance variables and properties on itself which will be used by the Schedule when the ScheculedApp instantiates it passing this configuration object. The Schedule will then use the configuration java object to initialize itself.

Specified by:

init in interface EnterpriseConfigurationObject

Throws:

EnterpriseConfigurationObjectException - if errors occur processing the configuration Element.
