Attribute service provides a generic service used to store and retrieve security attributes.

Attribute keys will be used to perform operations to attributes, and will be unique within a JVM in attribute service.

Each key can be associated with at most one attribute.

If the attribute passed in is null, the effect is the same as calling AttributeService.removeAttribute(String key).

If the attribute doesn't exists, it is added. Otherwise, the old attribute is updated.

oracle.security.jps.service.attribute.AttributeAccessPermission is required.

Parameters:

key - the key whose associated attribute is to be added or updated

attribute - the attribute to be associated with the specified key

Throws:

AttributeServiceException

java.security.AccessControlException - thrown if a requested access to attribute was denied

getAttribute

java.lang.Object getAttribute(java.lang.String key)
                              throws AttributeServiceException,

attribute the attribute to which the specified key is associating, or null if the attribute doesn't exists
