  - getRelationship
```
UserRelationship getRelationship(BasicUser basicUser,
                                 BasicUser related)
```
    Returns the relationship level between 2 users
  - getRequiredValues
```
Collection<?> getRequiredValues(Permission permission)
```
    Returns the required values to be enforced on the given permission. Required values are obtained from permissions which are granted / denied according to a collection of related entities on products. For example, the permission to perform a payment comes from having related payment types.
  - hasValue
```
default boolean hasValue(Permission permission,
                         Object... values)
```
    Returns whether the logged user has access to ALL the given values for the given permission. If the permission is not related to values, returns false
  - isAdminOf
```
boolean isAdminOf(User admin,
                  BasicUser user)
```
    Returns whether the given user is an administrator of the given user. An administrator is never an administrator of himself.
  - isBrokerOf
```
boolean isBrokerOf(BasicUser broker,
                   BasicUser user)
```
    Returns whether the given user is a broker of the given user. A broker is never a broker of himself.
  - manages
```
boolean manages(BasicUser manager,
                BasicUser basicUser)
```
    Returns whether the first user manages the second user. A user or any of his operators (restricted or not) always manages himself (i.e operator.manages(owner) is true).
  - permission
```
UserPermissionCheck permission(BasicUser user)
```
    Returns an UserPermissionCheck for the logged user over the given user
  - permission
```
PermissionCheck permission(Permission permission)
```
    Returns a PermissionCheck for the logged user with a permission which is not related to users
  - permissionOptionalValue
```
UserPermissionCheck permissionOptionalValue(BasicUser user)
```
    Returns an UserPermissionCheck for the logged user over the given user, optionally checking related values
  - permissionOptionalValue
```
PermissionCheck permissionOptionalValue(Permission permission)
```
    Returns a PermissionCheck which can check any type of permission and, optionally, related values. Never checks users.
  - relatesTo
```
boolean relatesTo(BasicUser basicUser,
                  BasicUser related)
```
    Returns whether the first user is related to (is allowed to view) the second user
  - requiresValues
```
boolean requiresValues(Permission permission)
```
    Returns whether the given permission would require a value check for the currently logged user
