Method Summary

Modifier and Type	Method	Description
protected LogManager	delegate()
void	logfOnce(Level pPriority, String pFormat, Object... pArgs)	Logging method similar to ForwardingLogManager.logf(Level, String, Object...), however, subsequent calls to this method with the same arguments will be silently ignored.
void	logOnce(Level pPriority, Object... pArgs)	Logging method similar to ForwardingLogManager.log(Level, Object...), however, subsequent calls to this method with the same arguments will be silently ignored.
void	logOnce(Level pPriority, Supplier<String> pMsgSupplier)	Logging method similar to ForwardingLogManager.log(Level, Supplier), however, subsequent calls to this method with the same arguments will be silently ignored.
void	resetSeenMessages()	Reset all seen log messages, such that logfOnce(Level, String, Object...) and logfOnce(Level, String, Object...) will be guaranteed to behave exactly like in a fresh instance of this class.
LogManagerWithoutDuplicates	withComponentName(String pName)	This method returns a new LogManagerWithoutDuplicates, which does not share state with the current instance (i.e., it is possible to log the same message both through the old and the new instance once).

Method Details

delegate

protected LogManager delegate()

Specified by:

delegate in class ForwardingLogManager

withComponentName

public LogManagerWithoutDuplicates withComponentName(String pName)

This method returns a new LogManagerWithoutDuplicates, which does not share state with the current instance (i.e., it is possible to log the same message both through the old and the new instance once).

Specified by:

withComponentName in interface LogManager

Parameters:

pName - A non-empty string.

Returns:

A LogManager instance.

• LogManager.withComponentName(String)

logOnce

public void logOnce(Level pPriority,
 Object... pArgs)

Logging method similar to ForwardingLogManager.log(Level, Object...), however, subsequent calls to this method with the same arguments will be silently ignored. Direct calls to ForwardingLogManager.log(Level, Object...) are not affected.

Make sure to call this method only with immutable parameters, such as Strings! If objects are changed after being passed to this method, detecting duplicate log messages may not work, or too many log messages may be ignored.

logOnce

public void logOnce(Level pPriority,
 Supplier<String> pMsgSupplier)

Logging method similar to ForwardingLogManager.log(Level, Supplier), however, subsequent calls to this method with the same arguments will be silently ignored. Direct calls to ForwardingLogManager.log(Level, Supplier) are not affected.

Make sure to call this method only with immutable parameters, such as Strings! If objects are changed after being passed to this method, detecting duplicate log messages may not work, or too many log messages may be ignored.

logfOnce

@FormatMethod
public void logfOnce(Level pPriority,
 String pFormat,
 Object... pArgs)

Logging method similar to ForwardingLogManager.logf(Level, String, Object...), however, subsequent calls to this method with the same arguments will be silently ignored. Direct calls to ForwardingLogManager.logf(Level, String, Object...) are not affected.

Make sure to call this method only with immutable parameters, such as Strings! If objects are changed after being passed to this method, detecting duplicate log messages may not work, or too many log messages may be ignored.

resetSeenMessages

public void resetSeenMessages()

Reset all seen log messages, such that logfOnce(Level, String, Object...) and logfOnce(Level, String, Object...) will be guaranteed to behave exactly like in a fresh instance of this class.
