## Detailed Description

ConsoleAppender appends log events to `stdout` or `stderr` using a layout specified by the user.

The default target is `stdout`.

## Member Function Documentation

void activateOptions | ( | log4cxx::helpers::Pool & | pool | ) |
| virtual

Derived appenders should override this method if option structure requires it.

Reimplemented from WriterAppender.

static const LogString& getSystemErr | ( |  | ) |
| static

static const LogString& getSystemOut | ( |  | ) |
| static

LogString getTarget | ( |  | ) | const

Returns the current value of the target property.

The default value of the option is "System.out".

See also setTarget.

void setOption | ( | const LogString & | option,
|  | const LogString & | value
| ) |  |
| virtual

Set `option` to `value`.

The handling of each option depends on the OptionHandler instance. Some options may become active immediately whereas other may be activated only when activateOptions is called.

Reimplemented from AppenderSkeleton.

void setTarget | ( | const LogString & | value | ) |

Sets the value of the target property.

Recognized values are "System.out" and "System.err". Any other value will be ignored.
