Examples of org.camunda.bpm.engine.authorization.Authorization

org.camunda.bpm.engine.authorization.Authorization
An {@link Authorization} assigns a set of {@link Permission Permissions}to an identity to interact with a given {@link Resource}.

EXAMPLES:
- User 'jonny' is authorized to start new instances of the 'invoice' process
- Group 'marketing' is not authorized to cancel process instances.
- Group 'marketing' is not allowed to use the tasklist application.
- Nobody is allowed to edit process variables in the cockpit application, except the distinct user 'admin'.
Identities

camunda BPM distinguished two types of identities: users and groups. Authorizations can either range over all users (userId = {@link #ANY}), an individual {@link User} or a {@link Group} of users.
Permissions

A {@link Permission} defines the way an identity is allowed to interactwith a certain resource. Examples of permissions are {@link Permissions#CREATE CREATE}, {@link Permissions#READ READ}, {@link Permissions#UPDATE UPDATE}, {@link Permissions#DELETE DELETE}, ... See {@link Permissions} for a set ofbuilt-in permissions.

A single authorization object may assign multiple permissions to a single user and resource:
```
 authorization.addPermission(Permissions.READ); authorization.addPermission(Permissions.WRITE); authorization.addPermission(Permissions.DELETE); 
```
On top of the built-in permissions, camunda BPM allows using custom permission types.

Resources

Resources are the entities the user interacts with. Examples of resources are {@link Resources#GROUP GROUPS}, {@link Resources#USER USERS}, process-definitions, process-instances, tasks ... See {@link Resources} for a setof built-in resource. The camunda BPM framework supports custom resources.

Authorization Type

There are three types of authorizations:
- Global Authorizations ( {@link #AUTH_TYPE_GLOBAL}) range over all users and groups (userId = {@link #ANY}) and are usually used for fixing the "base" permission for a resource.
- Grant Authorizations ( {@link #AUTH_TYPE_GRANT}) range over users and groups and grant a set of permissions. Grant authorizations are commonly used for adding permissions to a user or group that the global authorization revokes.
- Revoke Authorizations ( {@link #AUTH_TYPE_REVOKE}) range over users and groups and revoke a set of permissions. Revoke authorizations are commonly used for revoking permissions to a user or group the the global authorization grants.
Authorization Precedence

Authorizations may range over all users, an individual user or a group of users or . They may apply to an individual resource instance or all instances of the same type (resourceId = {@link #ANY}). The precedence is as follows:
1. An authorization applying to an individual resource instance preceds over an authorization applying to all instances of the same resource type.
2. An authorization for an individual user preceds over an authorization for a group.
3. A Group authorization preced over a {@link #AUTH_TYPE_GLOBAL GLOBAL} authorization.
4. A Group {@link #AUTH_TYPE_REVOKE REVOKE} authorization preced over a Group{@link #AUTH_TYPE_GRANT GRANT} authorization.
