Detailed Description

Provide a light-weight way to check active() before string formatting.

Definition at line 204 of file Journal.h.

Constructor & Destructor Documentation

◆ Stream() [1/3]

beast::Journal::Stream::Stream ( )

explicit

Create a stream which produces no output.

Definition at line 208 of file Journal.h.

◆ Stream() [2/3]

beast::Journal::Stream::Stream	(	Sink &	sink,
		Severity	level
	)

Create a stream that writes at the given level.

Constructor is inlined so checking active() very inexpensive.

Definition at line 217 of file Journal.h.

◆ Stream() [3/3]

beast::Journal::Stream::Stream ( Stream const & other )

Construct or copy another Stream.

Definition at line 225 of file Journal.h.
