Interface Privilege

public interface Privilege

A privilege represents the capability of performing a particular set of operations on items in the JCR repository. Each privilege is identified by a JCR name. JCR defines a set of standard privileges in the jcr namespace. Implementations may add additional privileges in namespaces other than jcr.

A privilege may be an aggregate privilege. Aggregate privileges are sets of other privileges. Granting, denying, or testing an aggregate privilege is equivalent to individually granting, denying, or testing each privilege it contains. The privileges contained by an aggregate privilege may themselves be aggregate privileges if the resulting privilege graph is acyclic.

A privilege may be an abstract privilege. Abstract privileges cannot themselves be granted or denied, but can be composed into aggregate privileges which are granted or denied.

A privilege can be both aggregate and abstract.

Since:

JCR 2.0

Method Summary

Privilege[]	getAggregatePrivileges() If this privilege is an aggregate privilege, returns the privileges it contains, the privileges contained by any aggregate privileges among those, and so on (the transitive closure of privileges contained by this privilege).
Privilege[]	getDeclaredAggregatePrivileges() If this privilege is an aggregate privilege, returns the privileges directly contained by the aggregate privilege.
String	getName() Returns the name of this privilege.
boolean	isAbstract() Returns whether this privilege is an abstract privilege.
boolean	isAggregate() Returns whether this privilege is an aggregate privilege.

Field Detail

JCR_READ

static final String JCR_READ

A constant representing jcr:read (in extended form), the privilege to retrieve a node and get its properties and their values.

JCR_MODIFY_PROPERTIES

static final String JCR_MODIFY_PROPERTIES

A constant representing jcr:modifyProperties (in extended form), the privilege to create, modify and remove the properties of a node.

JCR_ADD_CHILD_NODES

static final String JCR_ADD_CHILD_NODES

A constant representing jcr:addChildNodes (in extended form), the privilege to create child nodes of a node.

Constant Field Values

JCR_REMOVE_NODE

static final String JCR_REMOVE_NODE

A constant representing jcr:removeNode (in extended form), the privilege to remove a node.

In order to actually remove a node requires jcr:removeNode on that node and jcr:removeChildNodes on the parent node.

The distinction is provided in order to reflect implementations that internally model "remove" as a "delete" instead of a "unlink". A repository that uses the "delete" model can have jcr:removeChildNodes in every access control policy, so that removal is effectively controlled by jcr:removeNode.

JCR_REMOVE_CHILD_NODES

static final String JCR_REMOVE_CHILD_NODES

A constant representing jcr:removeChildNodes (in extended form), the privilege to remove child nodes of a node. In order to actually remove a node requires jcr:removeNode on that node and jcr:removeChildNodes on the parent node.

The distinction is provided in order to reflect implementations that internally model "remove" as a "unlink" instead of a "delete". A repository that uses the "unlink" model can have jcr:removeNode in every access control policy, so that removal is effectively controlled by jcr:removeChildNodes.
