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

public static Object getScopeService(IScope scope,
                                     Class<?> intf)

Returns scope service that implements a given interface.

Parameters:

scope - The scope service belongs to

intf - The interface the service must implement

Returns:

Service object

getScopeService

public static Object getScopeService(IScope scope,
                                     Class<?> intf,
                                     boolean checkHandler)

getScopeService

public static Object getScopeService(IScope scope,
                                     Class<?> intf,

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

getScopeService
