DaemonPermission

final public class DaemonPermission extends Permission (Code)

This class represents the permissions to control and query the status of a Daemon. A DaemonPermission consists of a target name and a list of actions associated with it.

In this specification version the only available target name for this permission is "control", but further releases may add more target names to fine-tune the access that needs to be granted to the caller.

Actions are defined by a string of comma-separated values, as shown in the table below. The empty string implies no permission at all, while the special "*" value implies all permissions for the given name:

Target"Name Action Description

"control" "start" The permission to call the start() method in an instance of a DaemonController interface.

"stop" The permission to call the stop() method in an instance of a DaemonController interface.

"shutdown" The permission to call the shutdown() method in an instance of a DaemonController interface.

"reload" The permission to call the reload() method in an instance of a DaemonController interface.

"*" The special wildcard action implies all above-mentioned action. This is equal to construct a permission with the "start, stop, shutdown, reload" list of actions.

	Return the hash code for this `DaemonPermission` instance. An hash code value.

implies
public boolean implies(Permission permission)(Code)
	Check if this `DaemonPermission` implies another `Permission`. true or false wether the specified permissionis implied by this `DaemonPermission` instance ornot.
