    Parameters:
    
    level - The LogLevel for this record.
    
    See Also:
    
    getLevel(), LogLevel
  - isSevereLevel
```
public abstract boolean isSevereLevel()
```
    Abstract method. Must be overridden to indicate what log level to show in red.
  - hasThrown
```
public boolean hasThrown()
```
    Returns:
    
    true if getThrown().toString() is a non-empty string.

  - getCategory
```
public String getCategory()
```
    Get the category asscociated with this LogRecord. For a more detailed description of what a category is see setCategory().
    
    Returns:
    
    The category of this record.
    
    See Also:
    
    setCategory(String)
  - setCategory
```
public void setCategory(String category)
```
    Set the category associated with this LogRecord. A category represents a hierarchical dot (".") separated namespace for messages. The definition of a category is application specific, but a common convention is as follows:
    When logging messages for a particluar class you can use its class name: com.thoughtworks.framework.servlet.ServletServiceBroker.
    
    Futhermore, to log a message for a particular method in a class add the method name: com.thoughtworks.framework.servlet.ServletServiceBroker.init().
    
    Parameters:
    
    category - The category for this record.
    
    See Also:
    
    getCategory()
  - getMessage
```
public String getMessage()
```
    Get the message asscociated with this LogRecord.
    
    Returns:
    
    The message of this record.
    
    See Also:
    
    setMessage(String)
  - setMessage
```
public void setMessage(String message)
```
    Set the message associated with this LogRecord.
    
    Parameters:
    
    message - The message for this record.
    
    See Also:
    
    getMessage()
  - getSequenceNumber
```
public long getSequenceNumber()
```
    Get the sequence number associated with this LogRecord. Sequence numbers are generally assigned when a LogRecord is constructed. Sequence numbers start at 0 and increase with each newly constructed LogRocord.
    
    Returns:
    
    The sequence number of this record.
    
    See Also:
    
    setSequenceNumber(long)
  - setSequenceNumber
```
public void setSequenceNumber(long number)
```
    Set the sequence number assocsiated with this LogRecord. A sequence number will automatically be assigned to evey newly constructed LogRecord, however, this method can override the value.
    
    Parameters:
    
    number - The sequence number.
    
    See Also:
    
    getSequenceNumber()
  - getMillis
```
public long getMillis()
```
    Get the event time of this record in milliseconds from 1970. When a LogRecord is constructed the event time is set but may be overridden by calling setMillis();
    
    Returns:
    
    The event time of this record in milliseconds from 1970.
    
    See Also:
    
    setMillis(long)
  - setMillis
```
public void setMillis(long millis)
```
    Set the event time of this record. When a LogRecord is constructed the event time is set but may be overridden by calling this method.
    
    Parameters:
    
    millis - The time in milliseconds from 1970.
    
    See Also:
    
    getMillis()
  - getThreadDescription
```
public String getThreadDescription()
```
    Get the thread description asscociated with this LogRecord. When a LogRecord is constructed, the thread description is set by calling: Thread.currentThread().toString(). You may supply a thread description of your own by calling the setThreadDescription(String) method.
    
    Returns:
    
    The thread description of this record.
    
    See Also:
    
    setThreadDescription(String)
  - setThreadDescription
```
public void setThreadDescription(String threadDescription)
```
    Set the thread description associated with this LogRecord. When a LogRecord is constructed, the thread description is set by calling: Thread.currentThread().toString(). You may supply a thread description of your own by calling this method.
    
    Parameters:
    
    threadDescription - The description of the thread for this record.
    
    See Also:
    
    getThreadDescription()
  - getThrownStackTrace
```
public String getThrownStackTrace()
```
    Get the stack trace in a String-based format for the associated Throwable of this LogRecord. The stack trace in a String-based format is set when the setThrown(Throwable) method is called.
    Why do we need this method considering that we have the getThrown() and setThrown() methods? A Throwable object may not be serializable, however, a String representation of it is. Users of LogRecords should generally call this method over getThrown() for the reasons of serialization.
    
    Returns:
    
    The Stack Trace for the asscoiated Throwable of this LogRecord.
    
    See Also:
    
    setThrown(Throwable), getThrown()
  - setThrownStackTrace
```
public void setThrownStackTrace(String trace)
```
    Set the ThrownStackTrace for the log record.
    
    Parameters:
    
    trace - A String to associate with this LogRecord
    
    See Also:
    
    getThrownStackTrace()
  - getThrown
```
public Throwable getThrown()
```
    Get the Throwable associated with this LogRecord.
    
    Returns:
    
    The LogLevel of this record.
    
    See Also:
    
    setThrown(Throwable), getThrownStackTrace()
  - setThrown
```
public void setThrown(Throwable thrown)
```
    Set the Throwable associated with this LogRecord. When this method is called, the stack trace in a String-based format is made available via the getThrownStackTrace() method.
    
    Parameters:
    
    thrown - A Throwable to associate with this LogRecord.
    
    See Also:
    
    getThrown(), getThrownStackTrace()
  - toString
```
public String toString()
```
    Return a String representation of this LogRecord.
    
    Overrides:
    
    toString in class Object
  - getNDC
```
public String getNDC()
```
    Get the NDC (nested diagnostic context) for this record.
    
    Returns:
    
    The string representing the NDC.
  - setNDC
```
public void setNDC(String ndc)
```
    Set the NDC (nested diagnostic context) for this record.
    
    Parameters:
    
    ndc - A string representing the NDC.
  - getLocation
```
public String getLocation()
```
    Get the location in code where this LogRecord originated.
    
    Returns:
    
    The string containing the location information.

```
public void setLocation(String location)
```
    Set the location in code where this LogRecord originated.
