Method Detail

isReadOnly

boolean isReadOnly()

Allows to inquire whether this identity service implementation provides read-only access to the user repository, false otherwise.

Read only identity service implementations do not support the following methods:

• newUser(String)
• saveUser(User)
• deleteUser(String)
• newGroup(String)
• saveGroup(Group)
• deleteGroup(String)
• newTenant(String)
• saveTenant(Tenant)
• deleteTenant(String)
• createMembership(String, String)
• deleteMembership(String, String)
• createTenantUserMembership(String, String)
• createTenantGroupMembership(String, String)
• deleteTenantUserMembership(String, String)
• deleteTenantGroupMembership(String, String)

If these methods are invoked on a read-only identity service implementation, the invocation will throw an UnsupportedOperationException.

Returns:

true if this identity service implementation provides read-only access to the user repository, false otherwise.
