Constructor Detail

### LogRecord

    public LogRecord()

Method Detail

### getLevel

    public LogLevel getLevel()

  Get the level of this LogRecord.

  Returns:
    The LogLevel of this record.
  See Also:
    `setLevel(LogLevel)`, `LogLevel`

### setLevel

    public void setLevel(LogLevel level)

  Set the level of this LogRecord.

  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.

### isFatal

    public boolean isFatal()

  Returns:
    true if isSevereLevel() or hasThrown() returns true.

### 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.

### setLocation

    public void setLocation(String location)

  Set the location in code where this LogRecord originated.

  Parameters:
    `location` - A string containing location information.

### resetSequenceNumber

    public static void resetSequenceNumber()

  Resets that sequence number to 0.

### getNextId

    protected static long getNextId()
