Constructor Details

ServicePermission

public ServicePermission(String name,
                         String action)
Create a new service permission with the indicated name and actions. The name is the name of the kerberos principal for the service. The actions are a comma-separated list of strings. The recognized actions are "initiate" and "accept". The "initiate" action means that the holder of the permission can access the service. The "accept" action means that the holder of the permission can operate as this service.
Parameters:
name - the prinicpal's name
action - the allowed actions

Method Details

equals

public boolean equals(Object obj)
Check to see if this object equals obj. Use implies, rather than equals, when making access control decisions.
Overrides:
equals in interface Permission
Parameters:
obj - the object to compare to

getActions

public String getActions()
Return a string representing the actions.
Overrides:
getActions in interface Permission

hashCode

public int hashCode()
This method returns a hash code for this Permission. It must satisfy the contract of Object.hashCode: it must be the same for all objects that equals considers to be the same.
Overrides:
hashCode in interface Permission
Returns:
a hash value

implies

public boolean implies(Permission perm)
This method tests whether this Permission implies that the specified Permission is also granted.
Overrides:
implies in interface Permission
Parameters:
perm - the Permission to test against
Returns:
true if perm is implied by this

newPermissionCollection

public PermissionCollection newPermissionCollection()
This method returns an empty PermissionCollection object that can store permissions of this type, or null if no such collection is defined. Subclasses must override this to provide an appropriate collection when one is needed to accurately calculate implies.
Overrides:
newPermissionCollection in interface Permission
Returns:
a new PermissionCollection
