Method Detail

### getSharedObjectNames

    Set<String> getSharedObjectNames(IScope scope)

  Get a set of the shared object names.

  Parameters:
    `scope` - the scope to return the shared object names from
  Returns:
    set containing the shared object names

### createSharedObject

    boolean createSharedObject(IScope scope,
                               String name,
                               boolean persistent)

  Create a new shared object.

  Parameters:
    `scope` - the scope to create the shared object in
    `name` - the name of the shared object
    `persistent` - will the shared object be persistent
  Returns:
    `true` if the shared object was created, otherwise `false`

### getSharedObject

    ISharedObject getSharedObject(IScope scope,
                                  String name)

  Get a shared object by name.

  Parameters:
    `scope` - the scope to get the shared object from
    `name` - the name of the shared object
  Returns:
    shared object, or `null` if not found

### getSharedObject

    ISharedObject getSharedObject(IScope scope,
                                  String name,
                                  boolean persistent)

  Get a shared object by name and create it if it doesn't exist.

  Parameters:
    `scope` - the scope to get the shared object from
    `name` - the name of the shared object
    `persistent` - should the shared object be created persistent
  Returns:
    the shared object

### hasSharedObject

    boolean hasSharedObject(IScope scope,
                            String name)

  Check if a shared object exists.

  Parameters:
    `scope` - the scope to check for the shared object
    `name` - the name of the shared object
  Returns:
    `true` if the shared object exists, otherwise `false`

### clearSharedObjects

    boolean clearSharedObjects(IScope scope,
                               String name)

  Deletes persistent shared objects specified by name and clears all properties from active shared objects (persistent and nonpersistent). The name parameter specifies the name of a shared object, which can include a slash (/) as a delimiter between directories in the path. The last element in the path can contain wildcard patterns (for example, a question mark [?] and an asterisk [*]) or a shared object name. The clearSharedObjects() method traverses the shared object hierarchy along the specified path and clears all the shared objects. Specifying a slash (/) clears all the shared objects associated with an application instance.

  The following values are possible for the soPath parameter:
  / clears all local and persistent shared objects associated with the instance.
  /foo/bar clears the shared object /foo/bar; if bar is a directory name, no shared objects are deleted.
  /foo/bar/* clears all shared objects stored under the instance directory /foo/bar. The bar directory is also deleted if no persistent shared objects are in use within this namespace.
  /foo/bar/XX?? clears all shared objects that begin with XX, followed by any two characters. If a directory name matches this specification, all the shared objects within this directory are cleared.

  If you call the clearSharedObjects() method and the specified path matches a shared object that is currently active, all its properties are deleted, and a "clear" event is sent to all subscribers of the shared object. If it is a persistent shared object, the persistent store is also cleared.

  Parameters:
    `scope` - the scope to check for the shared object
    `name` - the name of the shared object
  Returns:
    true if the shared object at the specified path was deleted; otherwise, false. If using wildcard characters to delete multiple files, the method returns true only if all the shared objects matching the wildcard pattern were successfully deleted; otherwise, it will return false.
