Class std.experimental.logger.core.Logger
This class is the base of every logger. In order to create a new kind of
logger a deriving class needs to implement the writeLogMsg method. By
default this is not thread-safe.
class Logger
;
It is also possible to override the three methods beginLogMsg,
logMsgPart and finishLogMsg together, this option gives more
flexibility.
Constructors
| Name | Description |
|---|---|
this
(lv)
|
Every subclass of Logger has to call this constructor from their
constructor. It sets the LogLevel, and creates a fatal handler. The fatal
handler will throw an Error if a log call is made with level
LogLevel.
|
Properties
| Name | Type | Description |
|---|---|---|
fatalHandler[get, set]
|
void delegate() | This delegate is called in case a log message with
LogLevel gets logged.
|
logLevel[get, set]
|
LogLevel | The LogLevel determines if the log call are processed or dropped
by the Logger. In order for the log call to be processed the
LogLevel of the log call must be greater or equal to the LogLevel
of the logger.
|
Methods
| Name | Description |
|---|---|
forwardMsg
(payload)
|
This method allows forwarding log entries from one logger to another. |
log
(ll, condition, args)
|
This method logs data with the LogLevel of the used Logger.
|
log
(ll, args)
|
This function logs data to the used Logger with a specific
LogLevel.
|
log
(condition, args)
|
This function logs data to the used Logger depending on a
explicitly passed condition with the LogLevel of the used
Logger.
|
log
(args)
|
This function logs data to the used Logger with the LogLevel
of the used Logger.
|
logf
(ll, condition, msg, args)
|
This function logs data to the used Logger with a specific
LogLevel and depending on a condition in a printf-style manner.
|
logf
(ll, msg, args)
|
This function logs data to the used Logger with a specific
LogLevel in a printf-style manner.
|
logf
(condition, msg, args)
|
This function logs data to the used Logger depending on a
condition with the LogLevel of the used Logger in a
printf-style manner.
|
logf
(msg, args)
|
This method logs data to the used Logger with the LogLevel
of the this Logger in a printf-style manner.
|
factory
(classname)
|
Create instance of class specified by the fully qualified name classname. The class must either have no constructors or have a default constructor. |
opCmp
(o)
|
Compare with another Object obj. |
opEquals
(o)
|
Test whether this is equal to o.
The default implementation only compares by identity (using the is operator).
Generally, overrides for opEquals should attempt to compare objects by their contents.
|
toHash
()
|
Compute hash function for Object. |
toString
()
|
Convert Object to a human readable string. |
finishLogMsg
()
|
Signals that the message has been written and no more calls to
logMsgPart follow.
|
logMsgPart
(msg)
|
Logs a part of the log message. |
writeLogMsg
(payload)
|
A custom logger must implement this method in order to work in a
MultiLogger and ArrayLogger.
|
Inner structs
| Name | Description |
|---|---|
LogEntry
|
LogEntry is a aggregation combining all information associated with a log message. This aggregation will be passed to the method writeLogMsg. |
