- Title: Base class for objects used in script applications
- Parent: CObj, Derived classes: XPlot, XGraph, XWave
The class CObjEx is an enhanced base class designed for objects which are used in STx scripts. Objects based on this class are deleted automatically before the script application is finished. By convention a class based on CObjEx implements the following simple instantiation method:
cobjExInstance := cobjExClassName constructionArguments
- Constructor
- The default constructor calls the CObj constructor and writes a construct-message in the console window. The function takes no arguments and returns always 0 (success). It must be called by derived classes.
- Destructor
- The default constructor stops and deletes the internal timer (&logTimerItem), calls the CObj constructor and writes a destruct-message in the console window. It must be called by derived classes.
Cleanup
static
CObjEx Cleanup- Result
- none:
- Description
- Delete all instances of classes based on
CObjEx. This function is called automatically by the script processor (BScript) before the script application exits.
Log
public
cobjex log text-
- text
- The text to write to the log window.
- Result
- none
- Description
- Write the message
class-instance: textto the script console.
LogExit
cobjex logError result; text-
- result
- The result to assign after returning.
- text
- The text to write to the console window.
- Result
- The value of argument result
- Description
- Writes the message
class-instance: textto the script console and exits from 2 macros (= return from caller) with the return value result.
Usage:
LogExt
Write text to the CON log window with the option of overwriting the last line. This is useful for progress reports.
Usage:
inst LogExt mode ; text
Parameters:
- mode
- If
0, the text overwrites the last log window line. If1, the text is appended to the last log window line.
- text
- The text to write to the log window.
LogTimer
Start or stop the internal BScript timer. The elapsed time is written to the CON log window.
Usage:
inst LogTimer cmd
Parameters:
- cmd
- One of the following:
ON|BEGIN- Start the timer. If the timer has already been started, then the elapsed time in seconds is returned. The elapsed time is also displayed in the CON window.
OFF|END- Stop the timer. The elapsed time is also displayed in the CON window.
ELog
cobjex ELog level ; result ; text-
- level
- The number of macro levels to return (
2means: return from calling-macro). - result
- The result to set on returning.
- text
- The text to write to the console window.
- Result
- The value of the argument result. Note: This value is returned to macro addressed by argument level.
- Description
- Writes the message
class-instance: ERROR - textto the script console and exits from level macros with the return value result.
