ScriptForge.Services service

The main purpose of the Services module is to provide access to the CreateScriptService method, which can be called in user scripts to instantiate services that are implemented using the ScriptForge framework.

A ScriptForge terminológiájában a szolgáltatás olyan metódusok és tulajdonságok gyűjteménye, amelyek közös célra használhatók. Például a String szolgáltatás a karakterláncok manipulálására szolgáló módszereket biztosít, míg a FileSystem szolgáltatás a fájlok és mappák manipulálását teszi lehetővé.

tip

A ScriptForge programkönyvtár Services modulja további metódusokat biztosít, amelyeket vagy belsőleg használnak a rendelkezésre álló szolgáltatások regisztrálására, vagy olyan fejlesztők használják, akik új szolgáltatások létrehozásával szeretnék bővíteni a ScriptForge-ot. A felhasználói parancsfájlok számára az egyetlen releváns metódus a CreateScriptService.


CreateScriptService

This method is used to instantiate a ScriptForge service so it can be called in user scripts.

The returned value is a Basic object or Nothing if an error occurred.

Szintaxis:

svc.CreateScriptService(service: str, [arg0: any] ...): svc

Paraméterek:

service: The name of the service identified as a string in the format "library.service":

arg0, ...: A list of arguments required by the invoked service.

If the first argument refers to an event manager, then arg0 is mandatory and must be the UNO object representing the event provided as argument to the user macro.

Példa:

In Basic

    GlobalScope.BasicLibraries.loadLibrary("ScriptForge")
    ' To be done once
    Dim svc As Object
    Set svc = CreateScriptService("Array")
    ' Refers to the "ScriptForge.Array" service or SF_Array
    Set svc = CreateScriptService("ScriptForge.Dictionary")
    ' Returns a new empty dictionary class instance; "ScriptForge." is optional
    Set svc = CreateScriptService("SFDocuments.Calc")
    ' Refers to the Calc service, implemented in the associated SFDocuments library
    Set svc = CreateScriptService("Timer", True)
    ' Returns a Timer class instance starting immediately
    Set svc = CreateScriptService("SFDocuments.DocumentEvent", oEvent)
    ' Refers to the DocumentEvent service implemented in the associated SFDocuments library
    ' Returns the instance of the Document class that fired the event
  
In Python

    from scriptforge import CreateScriptService
    svc = CreateScriptService("Array")
    svc = CreateScriptService("ScriptForge.Dictionary")
    svc = CreateScriptService("SFDocuments.Calc")
    svc = CreateScriptService("Timer", True)
    svc = CreateScriptService("SFDocuments.DocumentEvent", oEvent)
  

Python scripts support keyword arguments when calling CreateScriptService. The following example illustrates this concept by instantiating the Timer and Document services using keyword arguments.


    from scriptforge import CreateScriptService
    # Timer
    my_timer = CreateScriptService("Timer", start = True)
    # Document
    my_doc = CreateScriptService("Document", windowname = "some_file.ods")
  
tip

To make writing Python scripts more fluid, ScriptForge provides the Basic service which allows Python scripts to call a collection of methods with the same syntax and meaning as their homonymous native Basic functions.


The following example instantiates the Basic service and calls the MsgBox method, which is equivalent to the MsgBox function available in Basic:


    from scriptforge import CreateScriptService
    bas = CreateScriptService("Basic")
    bas.MsgBox("Hello World!")
  
note

Beware that the Basic service has to be instantiated in Python scripts using the CreateScriptService method.

All ScriptForge Basic routines or identifiers that are prefixed with an underscore character "_" are reserved for internal use. They are not meant be used in Basic macros or Python scripts.
