Member Function Documentation
| bool configureLayout | ( | ) | [virtual, inherited] |
Optionally create a layout according to layoutName and layoutPattern.
- Precondition:
- !appender, if you want a layout to actually be created
- Returns:
- true if not layout or no appender or a layout was created successfully, otherwise false
- Todo:
- ensure "" != layoutPattern?
Definition at line 29 of file Appender.cpp.
| void processEvents | ( | int | n | ) | [protected, virtual, inherited] |
Process up n events.
- Parameters:
-
n if 0 ==n then process events until buffer is empty, otherwise process at most n events
- Precondition:
- 0 <= n (otherwise acts as though n==1)
Definition at line 104 of file Appender.cpp.
References LoggingEvent::toLog4cpp().
| bool startHook | ( | ) | [virtual, inherited] |
ensure port is connected before we start
- Todo:
- input ports must be connected?

Member Data Documentation
RTT::InputPort<OCL::logging::LoggingEvent> log_port [protected, inherited] |
Port we receive logging events on Initially unconnected.
The logging service connects appenders.
Definition at line 47 of file Appender.hpp.
int maxEventsPerCycle [protected] |
Maximum number of log events to pop per cycle.
Defaults to 1.
A value of 0 indicates to not limit the number of events per cycle. With enough event production, this could lead to thread starvation!
