Constructor & Destructor Documentation

PyLogger()

RootUtils::PyLogger::PyLogger	(	PyObject *	debugfn,
		PyObject *	errorfn
	)

Constructor.

Parameters

debugfn	Function to call for a debug message.
errorfn	Function to call for an error message.

The functions should take a single string parameter. Passing None means to skip the call.

Definition at line 27 of file PyLogger.cxx.

  : m_debugfn (debugfn),
    m_errorfn (errorfn)
{
  Py_INCREF (debugfn);
  Py_INCREF (errorfn);
}

~PyLogger()

RootUtils::PyLogger::~PyLogger

(

)

Destructor.

Definition at line 39 of file PyLogger.cxx.

{
  Py_DECREF (m_debugfn);
  Py_DECREF (m_errorfn);
}

Member Function Documentation

call()

void RootUtils::PyLogger::call ( PyObject *  fn, const char *  msg  )

staticprivate

Common code to call Python callback.

Parameters

fn	The Python function to call (or None).
msg	The string to pass to it.

May raise an exception, if the Python code does.

Definition at line 73 of file PyLogger.cxx.

{
  if (!fn || fn == Py_None)
    return;
 
  PyObject* res = PyObject_CallFunction (fn, (char*)"s", msg);
  if (res == 0)
    throw RootUtils::PyException();
  Py_DECREF (res);
}

debug()

void RootUtils::PyLogger::debug ( const char *  msg )

virtual

Log a debugging message.

Parameters

msg	The message to log.

Implements RootUtils::ILogger.

{
  call (m_debugfn, msg);
}

error()

void RootUtils::PyLogger::error ( const char *  msg )

virtual

Log an error message.

Parameters

msg	The message to log.

Implements RootUtils::ILogger.
