## Detailed Description

This class can be used to redirect the log messages to a C++ stream.

Please note that this class is only available if wxWidgets was compiled with the standard iostream library support (`wxUSE_STD_IOSTREAM` must be on).

##

Library: wxBase
Category: Logging

## Public Member Functions

| wxLogStream (std::ostream *ostr=NULL)
| Constructs a log target which sends all the log messages to the given output stream.
Public Member Functions inherited from wxLog
wxLogFormatter * | SetFormatter (wxLogFormatter *formatter)
| Sets the specified formatter as the active one.
virtual void | Flush ()
| Some of wxLog implementations, most notably the standard wxLogGui class, buffer the messages (for example, to avoid showing the user a zillion of modal message boxes one after another – which would be really annoying).
void | LogRecord (wxLogLevel level, const wxString &msg, const wxLogRecordInfo &info)
| Log the given record.

## Additional Inherited Members

Static Public Member Functions inherited from wxLog
static void | AddTraceMask (const wxString &mask)
| Add the mask to the list of allowed masks for wxLogTrace().
static void | ClearTraceMasks ()
| Removes all trace masks previously set with AddTraceMask().
static const wxArrayString & | GetTraceMasks ()
| Returns the currently allowed list of string trace masks.
static bool | IsAllowedTraceMask (const wxString &mask)
| Returns true if the mask is one of allowed masks for wxLogTrace().
static void | RemoveTraceMask (const wxString &mask)
| Remove the mask from the list of allowed masks for wxLogTrace().
static void | DontCreateOnDemand ()
| Instructs wxLog to not create new log targets on the fly if there is none currently (see GetActiveTarget()).
static wxLog * | GetActiveTarget ()
| Returns the pointer to the active log target (may be NULL).
static wxLog * | SetActiveTarget (wxLog *logtarget)
| Sets the specified log target as the active one.
static wxLog * | SetThreadActiveTarget (wxLog *logger)
| Sets a thread-specific log target.
static void | FlushActive ()
| Flushes the current log target if any, does nothing if there is none.
static void | Resume ()
| Resumes logging previously suspended by a call to Suspend().
static void | Suspend ()
| Suspends the logging until Resume() is called.
static wxLogLevel | GetLogLevel ()
| Returns the current log level limit.
static bool | IsLevelEnabled (wxLogLevel level, wxString component)
| Returns true if logging at this level is enabled for the current thread.
static void | SetComponentLevel (const wxString &component, wxLogLevel level)
| Sets the log level for the given component.
static void | SetLogLevel (wxLogLevel logLevel)
| Specifies that log messages with level greater (numerically) than logLevel should be ignored and not sent to the active log target.
static bool | EnableLogging (bool enable=true)
| Globally enable or disable logging.
static bool | IsEnabled ()
| Returns true if logging is enabled at all now.
static bool | GetRepetitionCounting ()
| Returns whether the repetition counting mode is enabled.
static void | SetRepetitionCounting (bool repetCounting=true)
| Enables logging mode in which a log message is logged once, and in case exactly the same message successively repeats one or more times, only the number of repetitions is logged.
static const wxString & | GetTimestamp ()
| Returns the current timestamp format string.
static void | SetTimestamp (const wxString &format)
| Sets the timestamp format prepended by the default log targets to all messages.
static void | DisableTimestamp ()
| Disables time stamping of the log messages.
static bool | GetVerbose ()
| Returns whether the verbose mode is currently active.
static void | SetVerbose (bool verbose=true)
| Activates or deactivates verbose mode in which the verbose messages are logged as the normal ones instead of being silently dropped.
Protected Member Functions inherited from wxLog
virtual void | DoLogRecord (wxLogLevel level, const wxString &msg, const wxLogRecordInfo &info)
| Called to log a new record.
virtual void | DoLogTextAtLevel (wxLogLevel level, const wxString &msg)
| Called to log the specified string at given level.
virtual void | DoLogText (const wxString &msg)
| Called to log the specified string.

## Constructor & Destructor Documentation

wxLogStream::wxLogStream | ( | std::ostream * | ostr = `NULL` | ) |

Constructs a log target which sends all the log messages to the given output stream.

If it is NULL, the messages are sent to `cerr`.
