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
|
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
|
This method allows forwarding log entries from one logger to another. |
log
|
This method logs data with the LogLevel of the used Logger .
|
log
|
This function logs data to the used Logger with a specific
LogLevel .
|
log
|
This function logs data to the used Logger depending on a
explicitly passed condition with the LogLevel of the used
Logger .
|
log
|
This function logs data to the used Logger with the LogLevel
of the used Logger .
|
logf
|
This function logs data to the used Logger with a specific
LogLevel and depending on a condition in a printf -style manner.
|
logf
|
This function logs data to the used Logger with a specific
LogLevel in a printf -style manner.
|
logf
|
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
|
This method logs data to the used Logger with the LogLevel
of the this Logger in a printf -style manner.
|
factory
|
Create instance of class specified by the fully qualified name classname. The class must either have no constructors or have a default constructor. |
opCmp
|
Compare with another Object obj. |
opEquals
|
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
|
Logs a part of the log message. |
writeLogMsg
|
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. |
