Detailed Description

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

Definition at line 194 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 198 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 207 of file Journal.h.

◆ Stream() [3/3]

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

Construct or copy another Stream.

Definition at line 213 of file Journal.h.

Definition at line 222 of file Journal.h.

◆ level()

Severity beast::Journal::Stream::level ( ) const

Returns the Severity level of messages this Stream reports.

Definition at line 229 of file Journal.h.

◆ active()

explicit

Definition at line 242 of file Journal.h.

◆ operator<<() [1/3]
