LogRecord (Dracula Javadoc Sample)

java.lang.Object
- java.util.logging.LogRecord

All Implemented Interfaces:

Serializable
```
public class LogRecord
extends Object
implements Serializable
```
LogRecord objects are used to pass logging requests between the logging framework and individual log Handlers.
When a LogRecord is passed into the logging framework it logically belongs to the framework and should no longer be used or updated by the client application.
Note that if the client application has not specified an explicit source method name and source class name, then the LogRecord class will infer them automatically when they are first accessed (due to a call on getSourceMethodName or getSourceClassName) by analyzing the call stack. Therefore, if a logging Handler wants to pass off a LogRecord to another thread, or to transmit it over RMI, and if it wishes to subsequently obtain method name or class name information it should call one of getSourceClassName or getSourceMethodName to force the values to be filled in.
Serialization notes:
- The LogRecord class is serializable.
- Because objects in the parameters array may not be serializable, during serialization all objects in the parameters array are written as the corresponding Strings (using Object.toString).
- The ResourceBundle is not transmitted as part of the serialized form, but the resource bundle name is, and the recipient object's readObject method will attempt to locate a suitable resource bundle.
Since:

1.4

- Constructor Detail
  - LogRecord
```
public LogRecord(Level level,
                 String msg)
```
    Construct a LogRecord with the given level and message values.
    The sequence property will be initialized with a new unique value. These sequence values are allocated in increasing order within a VM.
    The millis property will be initialized to the current time.
    The thread ID property will be initialized with a unique ID for the current thread.
    All other properties will be initialized to "null".
    
    Parameters:
    
    level - a logging level value
    
    msg - the raw non-localized logging message (may be null)
- Method Detail
  - getLoggerName
```
public String getLoggerName()
```
    Get the source Logger's name.
    
    Returns:
    
    source logger name (may be null)
  - setLoggerName
```
public void setLoggerName(String name)
```
    Set the source Logger's name.
    
    Parameters:
    
    name - the source logger name (may be null)
  - getResourceBundle
```
public ResourceBundle getResourceBundle()
```
    Get the localization resource bundle
    This is the ResourceBundle that should be used to localize the message string before formatting it. The result may be null if the message is not localizable, or if no suitable ResourceBundle is available.
    
    Returns:
    
    the localization resource bundle
  - setResourceBundle
```
public void setResourceBundle(ResourceBundle bundle)
```
    Set the localization resource bundle.
    
    Parameters:
    
    bundle - localization bundle (may be null)
  - getResourceBundleName
```
public String getResourceBundleName()
```
    Get the localization resource bundle name
    This is the name for the ResourceBundle that should be used to localize the message string before formatting it. The result may be null if the message is not localizable.
    
    Returns:
    
    the localization resource bundle name
  - setResourceBundleName
```
public void setResourceBundleName(String name)
```
    Set the localization resource bundle name.
    
    Parameters:
    
    name - localization bundle name (may be null)
  - getLevel
```
public Level getLevel()
```
    Get the logging message level, for example Level.SEVERE.
    
    Returns:
    
    the logging message level
  - setLevel
```
public void setLevel(Level level)
```
    Set the logging message level, for example Level.SEVERE.
    
    Parameters:
    
    level - the logging message level
  - getSequenceNumber
```
public long getSequenceNumber()
```
    Get the sequence number.
    Sequence numbers are normally assigned in the LogRecord constructor, which assigns unique sequence numbers to each new LogRecord in increasing order.
    
    Returns:
    
    the sequence number
  - setSequenceNumber
```
public void setSequenceNumber(long seq)
```
    Set the sequence number.
    Sequence numbers are normally assigned in the LogRecord constructor, so it should not normally be necessary to use this method.
    
    Parameters:
    
    seq - the sequence number
  - getSourceClassName
```
public String getSourceClassName()
```
    Get the name of the class that (allegedly) issued the logging request.
    Note that this sourceClassName is not verified and may be spoofed. This information may either have been provided as part of the logging call, or it may have been inferred automatically by the logging framework. In the latter case, the information may only be approximate and may in fact describe an earlier call on the stack frame.
    May be null if no information could be obtained.
    
    Returns:
    
    the source class name
  - setSourceClassName
```
public void setSourceClassName(String sourceClassName)
```
    Set the name of the class that (allegedly) issued the logging request.
    
    Parameters:
    
    sourceClassName - the source class name (may be null)
  - getSourceMethodName
```
public String getSourceMethodName()
```
    Get the name of the method that (allegedly) issued the logging request.
    Note that this sourceMethodName is not verified and may be spoofed. This information may either have been provided as part of the logging call, or it may have been inferred automatically by the logging framework. In the latter case, the information may only be approximate and may in fact describe an earlier call on the stack frame.
    May be null if no information could be obtained.
    
    Returns:
    
    the source method name
  - setSourceMethodName
```
public void setSourceMethodName(String sourceMethodName)
```
    Set the name of the method that (allegedly) issued the logging request.
    
    Parameters:
    
    sourceMethodName - the source method name (may be null)
  - getMessage
```
public String getMessage()
```
    Get the "raw" log message, before localization or formatting.
    May be null, which is equivalent to the empty string "".
    This message may be either the final text or a localization key.
    During formatting, if the source logger has a localization ResourceBundle and if that ResourceBundle has an entry for this message string, then the message string is replaced with the localized value.
    
    Returns:
    
    the raw message string
  - setMessage
```
public void setMessage(String message)
```
    Set the "raw" log message, before localization or formatting.

```
    Set the parameters to the log message.
    
    Parameters:
    
    parameters - the log message parameters. (may be null)
  - getThreadID
```
