Constructor Detail

Trace

public Trace()

Trace

public Trace(int level,
     java.lang.String fileName)

The constructor with args. Note that I am not making any checks for fileName. The assumption is that a file name will always be supplied.

Method Detail

getLoggerForClass

public static final java.lang.Object getLoggerForClass(java.lang.Class<?> clazz)

resetTrace

public void resetTrace()

setTraceLevel

public void setTraceLevel(int level)

Call this method if trace is set and you need to change the trace level. In case the trace is not set and this method is invoked it will be a no op.

setNewTraceFile

public void setNewTraceFile(int level,
                   java.lang.String fileName)

In case a tracing is on, it will close the existing the trace file and open a new trace file. Note that there are 2 try/catch blocks so that we know where exactly the exception occurred.

getTraceFile

public java.lang.String getTraceFile()

getTraceLevel

public int getTraceLevel()

setTraceOS

public void setTraceOS(TraceOS traceOS)

getTraceOS

public TraceOS getTraceOS()

closeTraceFile

public void closeTraceFile()

writeTrace

public void writeTrace(int levelNum,
              java.lang.String stringInfo)

These are the methods that we require to write the data to the trace file.
