### ScopeUtils

    public ScopeUtils()

Method Detail

### resolveScope

    public static IScope resolveScope(IScope from,
                                      String path)

  Resolves scope for specified scope and path.

  Parameters:
    `from` - Scope to use as context (to start from)
    `path` - Path to resolve
  Returns:
    Resolved scope

### findRoot

    public static IScope findRoot(IScope from)

  Finds root scope for specified scope object. Root scope is the top level scope among scope's parents.

  Parameters:
    `from` - Scope to find root for
  Returns:
    Root scope object

### findApplication

    public static IScope findApplication(IScope from)

  Returns the application scope for specified scope. Application scope has depth of 1 and has no parent. See `isApp` method for details.

  Parameters:
    `from` - Scope to find application for
  Returns:
    Application scope.

### isAncestor

    public static boolean isAncestor(IBasicScope from,
                                     IBasicScope ancestor)

  Check whether one scope is an ancestor of another

  Parameters:
    `from` - Scope
    `ancestor` - Scope to check
  Returns:
    `true` if ancestor scope is really an ancestor of scope passed as from parameter, `false` otherwise.

### isRoot

    public static boolean isRoot(IBasicScope scope)

  Checks whether scope is root or not

  Parameters:
    `scope` - Scope to check
  Returns:
    `true` if scope is root scope (top level scope), `false` otherwise.

### isGlobal

    public static boolean isGlobal(IBasicScope scope)

  Check whether scope is the global scope (level 0 leaf in scope tree) or not When user connects the following URL: rtmp://localhost/myapp/foo/bar then / is the global level scope, myapp is app level, foo is room level and bar is room level as well (but with higher depth level)

  Parameters:
    `scope` - Scope to check
  Returns:
    `true` if scope is the global scope, `false` otherwise.

### isApp

    public static boolean isApp(IBasicScope scope)

  Check whether scope is an application scope (level 1 leaf in scope tree) or not

  Parameters:
    `scope` - Scope to check
  Returns:
    `true` if scope is an application scope, `false` otherwise.

### isRoom

    public static boolean isRoom(IBasicScope scope)

  Check whether scope is a room scope (level 2 leaf in scope tree or lower, e.g. 3, 4, ...) or not

  Parameters:
    `scope` - Scope to check
  Returns:
    `true` if scope is a room scope, `false` otherwise.

### getScopeService

    protected static Object getScopeService(IScope scope,
                                            String name)

  Returns scope service by bean name. See overloaded method for details.

  Parameters:
    `scope` - scope
    `name` - name
  Returns:
    object

### getScopeService

    protected static Object getScopeService(IScope scope,
                                            String name,
                                            Class<?> defaultClass)

  Returns scope services (e.g. SharedObject, etc) for the scope. Method uses either bean name passes as a string or class object.

  Parameters:
    `scope` - The scope service belongs to
    `name` - Bean name
    `defaultClass` - Class of service
  Returns:
    Service object

### getScopeService

### getScopeService

    public static Object getScopeService(IScope scope,

### getScopeService

    public static Object getScopeService(IScope scope,

                                         Class<?> defaultClass)

  Returns scope service that implements a given interface.

  Parameters:
    `scope` - The scope service belongs to
    `intf` - The interface the service must implement
    `defaultClass` - Class that should be used to create a new service if no service was found.
  Returns:
    Service object
