Detailed Description

A log object to stream messages.

Log objects are created to stream messages. They support all std::ostream compatible types.

Member Function Documentation

Create() [1/2]

static Log Create ( )

inlinestatic

Creates a dummy log.

Exceptions

Does	not throw any exception.

A dummy log will evaluate to false. and perform only NOPs. Dummy logs are used when logging is deactivated.

Create() [2/2]

static Log Create ( LogLevel logLevel )

inlinestatic

Creates a log with the given log level.

Parameters

[in]

logLevel

The log level.

Exceptions

Does	not throw any exception.

Log object to receive a message at the given level.

operator bool()

operator bool ( ) const

inlineexplicitnoexcept

Operator to evaluate as bool.

Dummy logs always evaluate to false. Otherwise logs evaluate to true.
