Modifier and Type	Method	Description
`boolean`	`contains(AccountGroup.UUID groupId)`	Returns `true` when the user this object was created for is a member of the specified group.
`boolean`	`containsAnyOf(Iterable<AccountGroup.UUID> groupIds)`	Returns `true` when the user this object was created for is a member of any of the specified group.
`Set<AccountGroup.UUID>`	`getKnownGroups()`	Returns the set of groups that can be determined by the implementation.

- Method Detail
  - contains
```
boolean contains(AccountGroup.UUID groupId)
```
    Returns true when the user this object was created for is a member of the specified group.
  - containsAnyOf
```
boolean containsAnyOf(Iterable<AccountGroup.UUID> groupIds)
```
    Returns true when the user this object was created for is a member of any of the specified group.
  - intersection
```
Set<AccountGroup.UUID> intersection(Iterable<AccountGroup.UUID> groupIds)
```
    Returns a set containing an input member of contains(id) is true.
    This is batch form of contains that returns specific group information. Implementors may implement the method as:
    Set<AccountGroup.UUID> r = new HashSet<>(); for (AccountGroup.UUID id : groupIds) if (contains(id)) r.add(id);
  - getKnownGroups
```
Set<AccountGroup.UUID> getKnownGroups()
```
    Returns the set of groups that can be determined by the implementation. This may not return all groups the contains(AccountGroup.UUID) would return true for, but will at least contain all top level groups. This restriction stems from the API of some group systems, which make it expensive to enumerate the members of a group.
