Class Poco::Channel

Library: Foundation
Package: Logging
Header: Poco/Channel.h

Description

The base class for all Channel classes.

Supports reference counting based garbage collection and provides trivial implementations of getProperty() and setProperty().

Direct Base Classes: Configurable, RefCountedObject

All Base Classes: Configurable, RefCountedObject

Known Derived Classes: AsyncChannel, ConsoleChannel, ColorConsoleChannel, FormattingChannel, Logger, EventLogChannel, FileChannel, SimpleFileChannel, SplitterChannel, StreamChannel, SyslogChannel, OpcomChannel, NullChannel, WindowsConsoleChannel, WindowsColorConsoleChannel, Poco::Net::RemoteSyslogListener, Poco::Net::RemoteSyslogChannel

Member Functions: close, getProperty, log, open, setProperty

Inherited Functions: duplicate, getProperty, referenceCount, release, setProperty

Creates the channel and initializes the reference count to one.

virtual ~Channel();

virtual void close();

Does whatever is necessary to close the channel. The default implementation does nothing.

std::string getProperty(
const std::string & name
) const;

virtual void log(
const Message & msg
) = 0;

Logs the given message to the channel. Must be overridden by subclasses.

If the channel has not been opened yet, the log() method will open it.

virtual void open();

Does whatever is necessary to open the channel. The default implementation does nothing.

void setProperty(
const std::string & name,
const std::string & value
);
