Class FwkStaticLibraryWriter

java.lang.Object

com.highqsoft.fwk.Fwk

com.highqsoft.fwk.exception.FwkStaticLibraryWriter

All Implemented Interfaces:

FwkInterface, java.io.Serializable

public class FwkStaticLibraryWriter
extends Fwk
implements FwkInterface

The FwkStaticLibraryWriter writes the exception to a dynamic linked library.

Under Windows NT it writes exceptions to the Windows NT EventLog. The generated event could be displayed with the EventView.

All the methods are static.

Inside the initializer the class tries to connect the err.dll. Wasn't this step successfully executed the writer isn't alive and could not be used. The function isAlive will return that state.

PutParams

public static void PutParams(int code,
             java.lang.String file,

             java.lang.String line,
             java.lang.String arameter)

Put an event to the event logger. When more than 10 (MAX_ERROR)identical events occurred the report of the event is suppressed.

The compiler definition NOTRACE suppresses the message AO_EVENT. The message AO_EVENT is used to trace back the calling sequence of the function where the error occurs.

If this function is called an error is occurred and the flag is set.

Parameters:

number - Number of the event to report.

file - Name of the sourcefile.

revision - Revision of the sourcefile.

ident - Identification string in the sourcefile.

parameter - Event parameter.
