public class CronJobs

extends MMObjectBuilder

implements Runnable

Builder that holds cronjobs and listens to changes. The builder also starts the CronDeamon. on startup the list of cronjobs is loaded into memory. The builder uses the bridge to get a cloud using class security.

Constructor Detail

CronJobs

public CronJobs()

Method Detail

run

public void run()

This thread wait's for MMBase to be started and then adds all the crontEntries to the CronDaemon

Specified by:

run in interface Runnable

insert

public int insert(String owner,
                  MMObjectNode objectNodenode)

Inserts a cronjob into the database, and create and adds a cronEntry to the CronDeamon

Overrides:

insert in class MMObjectBuilder

Parameters:

owner - The administrator creating the node

objectNodenode - The object to insert. The object need be of the same type as the current builder.

Returns:

An int value which is the new object's unique number, -1 if the insert failed.

commit

public boolean commit(MMObjectNode objectNodenode)

Commits a cronjob to the database. On commit of a cronjob, the job is first removed from the cronDeamon and a new cronEntry is created and added to the CronDaemon.

Overrides:

commit in class MMObjectBuilder

Parameters:

objectNodenode - The node to be committed

Returns:

true if commit successful

removeNode

public void removeNode(MMObjectNode objectNodenode)

removes the node from the database and also removes it from the CronDaemon

Overrides:

removeNode in class MMObjectBuilder

Parameters:

objectNodenode - The node to remove.

setDefaults

public void setDefaults(MMObjectNode node)

sets the default type and crontime (does not work)

Overrides:

setDefaults in class MMObjectBuilder

Parameters:

node - The node to set the defaults of.
