The scope object. A stateful object shared between a group of clients connected to the same `context path`. Scopes are arranged in hierarchical way, so its possible for a scope to have a parent and children scopes. If a client connects to a scope then they are also connected to its parent scope. The scope object is used to access resources, shared object, streams, etc. That is, scope are general option for grouping things in application. The following are all names for scopes: application, room, place, lobby.

Method Detail

### hasChildScope

    boolean hasChildScope(String name)

  Check to see if this scope has a child scope matching a given name.

  Parameters:
    `name` - the name of the child scope
  Returns:
    `true` if a child scope exists, otherwise `false`

### hasChildScope

    boolean hasChildScope(String type,
                          String name)

  Checks whether scope has a child scope with given name and type

  Parameters:

    `name` - Child scope name
  Returns:
    `true` if a child scope exists, otherwise `false`

### createChildScope

    boolean createChildScope(String name)

  Creates child scope with name given and returns success value. Returns `true` on success, `false` if given scope already exists among children.

  Parameters:
    `name` - New child scope name
  Returns:
    `true` if child scope was successfully creates, `false` otherwise

### addChildScope

    boolean addChildScope(IBasicScope scope)

  Adds scope as a child scope. Returns `true` on success, `false` if given scope is already a child of current.

  Parameters:
    `scope` - Scope given
  Returns:
    `true` if child scope was successfully added, `false` otherwise

### removeChildScope

    void removeChildScope(IBasicScope scope)

  Removes scope from the children scope list. Returns `false` if given scope isn't a child of the current scope.

  Parameters:
    `scope` - Scope given

### getScopeNames

    Iterator<String> getScopeNames()

  Get a set of the child scope names.

  Returns:
    set containing child scope names

### getBasicScopeNames

    Iterator<String> getBasicScopeNames(String type)

### getBasicScope

    `true` on success, `false` if given connection already belongs to this scope

### disconnect

    void disconnect(IConnection conn)

  Removes given connection from list of scope connections. This disconnects all clients of given connection from the scope.
