    Method Detail

    clearDictionaries

    public any clearDictionaries()

    Clear the internal cache dictionaries

    Returns:
    HandlerService

    defaultActionCheck

    public any defaultActionCheck(any event)

    Do a default action checks on the incoming event string. This method matches it against the internal handlers list. If found, then we append the default action to the event.

    Parameters:
    event - The request context
    Returns:
    HandlerService

    getEventCacheDictionary

    public string getEventCacheDictionary()

    getEventCaching

    public string getEventCaching()

    getEventCachingMetadata

    private struct getEventCachingMetadata(any ehBean, any oEventHandler)

    Return the event caching metadata for an action execution context.

    Parameters:
    ehBean - The event handler bean
    oEventHandler - The event handler to execute
    Returns:
    strc

    getEventMetadataEntry

    public struct getEventMetadataEntry(any targetEvent)

    Get an event string's metdata entry. If not found, then you will get a new metadata entry using the `getNewMDEntry()` method.

    Parameters:
    targetEvent - The event to match for metadata.

    getHandler

    public any getHandler(any ehBean, any requestContext)

    Get a validated handler instance using an event handler bean and context. This is called once event execution is in progress. Before returning this method verifies method of execution, event caching, invalid events and stores metadata

    Parameters:
    ehBean - The event handler bean representation
    requestContext - The request context object

    getHandlerBean

    public any getHandlerBean(string event)

    Parse the incoming event string into an event handler bean that is used for the current execution context

    Parameters:
    event - The full event string
    Returns:
    coldbox.system.web.context.EventHandlerBean

    getHandlerBeanCacheDictionary

    public string getHandlerBeanCacheDictionary()

    getHandlerCacheDictionary

    public string getHandlerCacheDictionary()

    getHandlerCaching

    public string getHandlerCaching()

    getHandlerListing

    public array getHandlerListing(any directory)

    Retrieve handler listings from disk

    Parameters:
    directory - The path to retrieve

    getNewMDEntry

    private struct getNewMDEntry()

    Return a new metadata struct object

    Returns:
    { cacheable:boolean, timeout, lastAccessTimeout, cacheKey, suffix }

    invalidEvent

    public any invalidEvent(string event, any ehBean)

    Invalid Event procedures

    Parameters:
    event - The event that was found to be invalid

    HandlerService
    Throws:
    EventHandlerNotRegisteredException,InvalidEventHandlerException

    isViewDispatch

    public boolean isViewDispatch(string event, any ehBean)

    Check if the incoming event has a matching implicit view to dispatch. This is usually called when there is no existing handler found.

    Parameters:
    event - The event string
    ehBean - The event handler bean

    newHandler

    public any newHandler(any invocationPath)

    Asks wirebox for an instance of a handler. It verifies that there is a mapping in Wirebox for the handler if it does not exist, it maps it first and then retrieves it.

    Parameters:
    invocationPath - The handler invocation path
    Returns:
    Handler Instance

    onConfigurationLoad

    public any onConfigurationLoad()

    Once configuration file loads setup the services with app specific variables
