Method Detail

getAlertRules

List<AlertRule> getAlertRules(String user)
                       throws LiveViewException

Gets all available alert rules from the server for the given user. A user name of "*" or null returns all users' alerts.

"user" is currently just an opaque string that is used as a key in setting and getting alerts. There is no validation or authentication done with or for this opaque string. Blocks until all AlertRules are returned.

Returns:

all AlertRules from the server for the given user, or all rules if user is *

Throws:

LiveViewException - if there is a problem with the request or network issue

AlertRule getAlertRule(long alertID)

Gets the alert rule specified by the id.

Returns:

the AlertRule that matches the id

Throws:

LiveViewException - if there is a problem with the request or network issue

createAlertRule

AlertRule createAlertRule()

Creates a new alert rule. The returned object must be added to the server once configured for it to take effect.

All of the properties of the returned AlertRule have initial values, but no initial value is guaranteed to be valid.

After valid property values have been assigned, the rule can be added to the server using AlertManager.setAlertRule(AlertRule)

Returns:

a new AlertRule
