Remarks

A decorator that uses a delegate to accept or ignore messages.

The filter can accept or reject messages based on both the message type and the actual message (format string). When someone calls IsEnabled(Severity), the filter is invoked with only the type; the message is set to null. Accepted messages are sent to the Target message sink.

Properties
Func< Severity, object?, string?, bool >	Filter [get, set]
Func< Severity, bool >	TypeFilter [get, set]
IMessageSink	Target [get, set]
