All Known Implementing Classes:

Bin2Data.CmdLine, C2DataDeps, CheckDeps.Cmdline, CmdHeader2Reflection, Csv2Data.CmdHandler, DocuGen.CmdLine, Filecmd.Cmdline, FileList.CmdLine, GenXmlCfgJavaData.CmdLine, GenZbnfJavaData.CmdLine, JZtxtcmd.CmdLine, MainCmd, MainCmdLoggingStream, ReportWrapperLog, SampleCmdLine.CmdLine, SCLstruct2Lists.CmdLine, Xsltpre.CmdLine, Zbnf2Text.CmdLineText, Zbnf2Xml.CmdLine, Zip.Cmdline, Zmake.CmdLine

public interface MainCmdLogging_ifc
extends LogMessage

This interface is the access to output log messages while running an application to check its work.

• One implementor is the MainCmd for command line programming or org.vishia.gral.area9.GralArea9MainCmd for the gral GUI.
• Another implementor independent of any other concept is MainCmdLoggingStream. That class adapts the standard System.out to this interface.
• Using MainCmdLoggingStream and MsgDispatchSystemOutErr one can create messages which can be dispatched to any destinations.

Dieses Interface dient zur Ausgabe von Logmeldungen for kommandozeilenartige Abarbeitung. This interface is usefull for reporting something (logfiles). It should be used in every algorithm routine to support debugging without using an extra debugger. It may help to encircle problems.

Version and history:

• 2012-11-10 Hartmut chg: Name of this interface changed from Report to MainCmdLogging_ifc: The identifier Report may be bad understanding, this interface is used as a logging interface. A report is more a summary presentation. TODO: rename all methods which starts with report.
• 2012-11-10 Hartmut inherits from LogMessage. This interface is used for log, but it contains some more.
• 2012-03-30 Hartmut new #getLogMessageErrorConsole()
• 2011-10-11 Hartmut new setOutputChannels(Appendable, Appendable). All outputs are redirect-able now. Used for output in a graphical text box.
• 2007-12-29 Hartmut some methods from mainCmd_ifc are displaced here. Thus the Report interface is revalued to write some informations also to the display with the capability to control the report levels for that in the implementation.
• 2006-01-07 Hartmut initial revision

nLevel - write the report only if the demand level is greater or equal.

nLeftMargin - determins a left margin. First a new line is outputted, followed by '*' and spaces.

string - String to write.

reportln

void reportln(int nLevel,
              java.lang.String string)

report begins at a new a line

Parameters:

nLevel - write the report only if the demand level is greater or equal.

string - String to write.

setExitErrorLevel

void setExitErrorLevel(int level)

set the exitErrorLevel of the maximum of given level of every call.

Parameters:

level - Errorlevel how defined in Report, 0 is the lowest level (successfull), >0 is worse.

setOutputChannels

void setOutputChannels(java.lang.Appendable outP,
                       java.lang.Appendable errP)

Sets destinations for output and error output. This method may allow to redirect output and error.

Parameters:

outP - Destination for output. If null, current output isn't change.

errP - Destination for error output. If null, current output isn't change.

setReportLevelToIdent

void setReportLevelToIdent(int ident,
                           int nLevelActive)

Sets a dedicated level number to the known output priorities. This method helps to define several levels to dispatch it.

Parameters:

nLevel - The number identifying a dedicated level. This number should be greater than the known priority levels, it means >= 10 or >=1000. Use dedicated group of numbers for an application.

nLevelActive - Ones of the known priotity levels Report.error to Report.fineDebug.
Example of using:

   class MyModule
   { /**Define module-specific numbers to identify a level. 
      * The numbers should be define regarding a band of numbers in the application.
      * /  
     static final int myReportLevel1 = 3500, myReportLevel2=3501; 
     
     void init()
     { setLevelActive(myReportLevel1, Report.info);  //This reports should be outputted always
       setLevelActive(myReportLevel2, Report.debug); //This reports are debug infos.
     }
     
     void processAnything()
     { report.reportln( myReportLevel1, "InfoText"); //It depends on the report level settings 
       report.reportln( myReportLevel2, "DebugText");//whether it is outputed or not. 
     }  
 

writeError

void writeError(java.lang.String sError)

Writes an error line. This method should be used instead a directly write via System.err.println(...). The using of System.err writes the output directly on console window of the command line, but in general, the user mostly don't want to write to the console, he will give an information out. In a GUI-application, this information can be displayed in a status line or scrolling output window. It may also be possible to write the information in a file additional. The implementation of this method writes the output in the conformed way to the application frame.
Before output, the previous line is terminated by a newline, or a status line will be cleared.

Parameters:

sError - The error text, it should be without such hot spot words line "!!!ERROR!!!", because the distinction in display should be done by the implementation of this method. A good sample is writeErrorln("cannot create file: " + sFileName);

writeError

void writeError(java.lang.String sError,
                java.lang.Throwable exception)

Writes an error line caused by an exception. This method should be used instead a directly write via System.err.println(...) and by catching an exception. The using of System.err writes the output directly on console window of the command line, but in general, the user mostly don't want to write to the console, he will give an information out. In a GUI-application, this information can be displayed in a status line or scrolling output window. It may also be possible to write the information in a file additional. The implementation of this method writes the output in the conformed way to the application frame.
Before output, the previous line is terminated by a newline, or a status line will be cleared.

Parameters:

sError - The error text, it should be without such hot spot words line "!!!ERROR!!!", because the distinction in display should be done by the implementation of this method. A good sample is writeErrorln("cannot create file: " + sFileName);

exception - The catched Exception. The getMessage()-part of the exception is written after sError. The stacktrace of the exception is written to report.

writeInfo

void writeInfo(java.lang.String sInfo)

Appends an info to the end of the previous info, @see #writeInfoln.

Parameters:

sInfo - String to be written.

writeInfoln

void writeInfoln(java.lang.String sInfo)

Writes an info line. This method should be used instead a directly write via System.out.println(...). The using of System.out writes the output directly on console window of the command line, but in general, the user mostly don't want to write to the console, he only will give an information out. In a GUI-application, this information can be displayed in a status line or scrolling output window. It may also be possible to write the information in a file additional. The implementation of this method writes the output in the conformed way to the application frame.
Before output, the previous line is terminated by a newline, or a status line will be cleared.

Parameters:

sInfo - String to be written.

writeStackTrace

void writeStackTrace(java.lang.Exception exc)

writeWarning

void writeWarning(java.lang.String sError)

Writes an error line. This method should be used instead a directly write via System.err.println(...). The using of System.err writes the output directly on console window of the command line, but in general, the user mostly don't want to write to the console, he will give an information out. In a GUI-application, this information can be displayed in a status line or scrolling output window. It may also be possible to write the information in a file additional. The implementation of this method writes the output in the conformed way to the application frame.
Before output, the previous line is terminated by a newline, or a status line will be cleared.

Parameters:

sError - The error text, it should be without such hot spot words line "!!!WARNING!!!", because the distinction in display should be done by the implementation of this method. A good sample is writeErrorln("file is empty: " + sFileName);
