Interface Capability

All Known Implementing Classes:

CapabilityImpl

public interface Capability

The basic interface to queries on security and privacy of a Node.

The static values represent the right to access the various restricted interfaces of a Node.

The READ permission represents access to the Content of a Node. Without this, a User may only access a Node's NID and Type.

The EDIT permission represents access to an Editor for a Node. Without this permission, a User may not modify the contents of a Node. When the owner of a Node removes his/her own EDIT permission, then the Node is read-only. An EDIT permission cannot be granted to anyone without READ permission.

The HISTORY permission allows a User access to the NodeHistory for a Node. This allows one to examine the audit trail or provenance of a Node.The DELEGATE_ permissions allows a User to delegate a subset of his own permissions to another User or revoke permissions previously delegated. If this permission is revoked, then all such delegated permissions are automatically revoked.

On creation, the owner of a Node is granted all of these permissions.
