ActionManager

  • This extension automatically monitors the database for objects that support the YapActionable protocol.

    Objects that support the YapActionable protocol relay information about actions that need to be taken. This information includes things such as:

    • when the action needs to be taken
    • if it should be retried, and if so what delay to use
    • whether or not the action requires an Internet connection
    • the block to invoke in order to trigger the action

    This extension handles all aspects related to scheduling & executing YapActionItems.

    Examples of YapActionItems include things such as:

    • deleting items when they expire e.g.: removing cached files
    • refreshing items when they’ve become stale e.g.: periodically updating user infromation from the server

    Declaration

    Objective-C

    @interface YapDatabaseActionManager : YapDatabaseAutoView

    Swift

    class YapDatabaseActionManager : YapDatabaseAutoView

  • This class is used by the YapDatabaseActionManager, and any model object(s) that need to interact with it.

    A YapActionItem encompasses a majority of the logic required to track when a particular action should occur concerning a particular model object.
