Description
The base class for all Channel classes.
Supports reference counting based garbage collection and provides trivial implementations of getProperty() and setProperty().

Member Functions: close, getProperty, log, open, setProperty
Inherited Functions: duplicate, getProperty, referenceCount, release, setProperty
Types Aliases
Ptr
using Ptr = AutoPtr < Channel >;
Constructors
Channel
Channel();
Creates the channel and initializes the reference count to one.
Destructor
~Channel 
virtual ~Channel();
Member Functions
close
virtual void close();
Does whatever is necessary to close the channel. The default implementation does nothing.
getProperty
std::string getProperty(
const std::string & name
) const;
Throws a PropertyNotSupportedException.
See also: Poco::Configurable::getProperty()
log
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.
open
virtual void open();
Does whatever is necessary to open the channel. The default implementation does nothing.
setProperty
void setProperty(
const std::string & name,
const std::string & value
);
Throws a PropertyNotSupportedException.
