    apeConnect(channel, connect_function, data_function, error_function)

    Opens up an AJAX Push Engine. This is a type of http based real time communication which uses the Umajin server as the central hub. Once a named channel is opened many applications can use this to send and receive broadcast messages.
    DEPRECATED: The APE functions will be removed in a future release of Umajin. See socketIOConnect for a replacement.
    Parameters:
    Name Type Description
    channel

    string

    		 a unique name for the communication channel
    connect_function

    string

    		 the name of a JavaScript function to use as a callback upon successful connection. It takes no paramters.
    data_function

    string

    		 the name of a JavaScript function to use as a callback when data is received through the channel. It takes two string parameters; the first parameter is the channel that data was received from and the second parameter is the data packet.

function ape_on_connect() {
    apeSend("demo");
}
function ape_on_data(pubid, data_in) {
    callAction("show_popup", data_in);
}

    apeSend(data)

    apeSend sends data through an AJAX Push Engine session that has been esablished by apeConnect. See apeConnect for an example of how to use the AJAX Push Engine.
    You are sending data to the channel established in the apeConnect function - you cannot send to another channel without reconnecting.
    DEPRECATED: The APE functions will be removed in a future release of Umajin. See socketIOSend for a replacement.

    bindEvent(obj, event, callback)

    bindEvent allows one of the supported events of the obj component to be handled by a custom event handler callback.
    NOTE: For custom components, it is recommended that bindEvent() is called from the on_init function callback which is declared in registerComponent. For dynamically created components within custom components, bindEvent() should called on those components within the callback of on an "on_ready" event.
    EventString has a list of the events you can bind to and the parameters passed.
    Parameters:
    Name Type Description
    obj

    object

    		 a component object. May also be "self" to refer to the current instance of a custom object.

    on_ready - Occurs when a custom component is made visible by explicit action - set visibility or animate. Does not occur when a page is shown. This is useful to call bindEvents on dynamically created components. (Custom component)
    callback

    function

    		 Function that will be be called to handle future instances of event. The parameters passed to callback may vary based on the event being handled.
    Example

    cacheDbOpen opens a SQLite DB on the devices local storage. If the DB does not exist it will be created.
    An SQLite DB is used for local settings and won't normally be synced during an Editor project save.
    The DB file can be set to sync on Editor save with the filename suffix "_sync.db" e.g, "sharemydb_sync.db". That, now populated, file will be downloaded to during a client project update. The updated file will overwrite the project-local DB file.
    After a DB is opened, it may be accessed with cacheDbSelectRaw and cacheDbExec.
    When done with a DB, it should be closed with cacheDbClose - however Umajin does it's best to clean this up for you if you forget.
    This system uses the excellent SQlite database, find out more here https://www.sqlite.org/lang.html
    Parameters:
    Name Type Description
    filename

    string

    		 this is the name of the db it will be stored in the local project cache folder and subfolders cannot be used
    If you use the special filename ":memory:" then an in-memory database will be created or opened - this type of database will be lost when the app finishes.
    Returns:
    true if the database was opened successfully, or was already open. False if the datbase cannot be opened or created
    Example
    var success = cacheDbOpen("mydb.db");

    raiseEvent(component, eventid, mydata)

    raiseEvent fires an event of a custom component or built-in Umajin component. It passes the mydata parameter to any actions that call the event.
    For custom components: The stringified eventid param needs to match an event declared in the registerComponent function, or EventString.
    For Umajin's built-in components: the stringifed eventid needs to be the name of the event in the editor converted to lower case with spaces replaced by '_'. e.g. "On Submit" would convert to "on_submit"
    The mydata parameter can be used to marshall any values to be exposed to the user of this action by adding them as named values in a stringified JSON packet in the style of "{"value":3, "color":"red"}". These will be available to users as [value] and [color] in any actions they apply to this event.
    Parameters:
    Name Type Description
    component

    object

    		 an instance of a component object. "self" refers to the current instance of a custom component from within that component's code.
    eventid

    string

    		 the string that identifies the event. For custom component you may use a property of EventString or a custom eventid. For built-in umajin components, it needs to be the Event name in the editor converted to lower case and spaces replaced with underscores.
    mydata

    string

    		 a JSON formatted object, with properties that correspond to the parameters that the event handler for eventid are expected to receive. To pass in no parameters, pass in a blank stringified JSON object, "{}"
    Examples
    // this passes the value varaible to the Action that handles the on_press event
raiseEvent(self, 'on_press','{"value":' + value + '}');
    var value = "hello";
raiseEvent(comp, "my_custom_event", "{mykey:" + value + "}"); // The mydata parameter needs to be stringified JSON. This can be accessed in an action (such as a text field) by using the variable [mykey]
& @example
raiseEvent(umajinButtonComp, "on_press", "{}"); // For an existing built in component. Note how the editor name is "On Press", however to correctly work we must use "on_press".

    webViewRunJavascript(web_view, script)

    webViewRunJavascript runs a JavaScript function call in the context of a Web View component's current displayed page.
    This allows performing updates to the web view without reloading it completely.
    Notes:

    • There is no way to return data. A workaround for this is to change page #anchor in the URL, by setting
      window.location.hash; and handle the Web View's On URL Change (on_url_change) event.
    • Although some platforms may support more complex JS, a simple function call is the most widely supported.
      Therefore, you should wrap all the logic for the changes you wish to make into a JS function inside the
      displayed web page, and then call that using this function.
    Parameters:
    Name Type Description
    web_view

    object

    		 an instance of a Web View component
    script

    string

    		 the JavaScript function call to run.
