LogEvent (reload4j 1.2.25 API)

java.lang.Object
- org.apache.log4j.pattern.LogEvent

All Implemented Interfaces:

Serializable
```
public class LogEvent
extends Object
implements Serializable
```
This class is a copy of o.a.l.spi.LoggingEvent from log4j 1.2.15 which has been renamed to keep the same overall class name length to allow a serialization written with a prior instance of o.a.l.spi.LoggingEvent to be deserialized with this class just by mangling the class name in the byte stream.

    Deprecated. This field will be marked as private in future releases. Please do not access it directly. Use the getLevel() method instead.
    
    Level of logging event. Level cannot be serializable because it is a flyweight. Due to its special seralization it cannot be declared final either.

    Since:
    
    1.2.15
- Method Detail
  - getLocationInformation
```
public LocationInfo getLocationInformation()
```
    Set the location information for this logging event. The collected information is cached for future use.
  - getLevel
```
public Level getLevel()
```
    Return the level of this event. Use this form instead of directly accessing the level field.
  - getLoggerName
```
public String getLoggerName()
```
    Return the name of the logger. Use this form instead of directly accessing the categoryName field.
  - getMessage
```
public Object getMessage()
```
    Return the message for this logging event.
    Before serialization, the returned object is the message passed by the user to generate the logging event. After serialization, the returned value equals the String form of the message possibly after object rendering.
    
    Since:
    
    1.1
  - getNDC
```
public String getNDC()
```
    This method returns the NDC for this event. It will return the correct content even if the event was generated in a different thread or even on a different machine. The NDC.get() method should never be called directly.
  - getMDC
```
public Object getMDC(String key)
```
    Returns the the context corresponding to the key parameter. If there is a local MDC copy, possibly because we are in a logging server or running inside AsyncAppender, then we search for the key in MDC copy, if a value is found it is returned. Otherwise, if the search in MDC copy returns a null result, then the current thread's MDC is used.
    Note that both the local MDC copy and the current thread's MDC are searched.
  - getMDCCopy
```
public void getMDCCopy()
```
    Obtain a copy of this thread's MDC prior to serialization or asynchronous logging.
  - getRenderedMessage
```
public String getRenderedMessage()
```
  - getStartTime
```
public static long getStartTime()
```
    Returns the time when the application started, in milliseconds elapsed since 01.01.1970.
  - getThreadName
```
public String getThreadName()
```
  - getThrowableInformation
```
public ThrowableInformation getThrowableInformation()
```
    Returns the throwable information contained within this event. May be null if there is no such information.
    Note that the Throwable object contained within a ThrowableInformation does not survive serialization.
    
    Since:
    
    1.1
  - getThrowableStrRep
```
public String[] getThrowableStrRep()
```
    Return this event's throwable's string[] representaion.
  - setProperty
```
public final void setProperty(String propName,
                              String propValue)
```
    Set value for MDC property. This adds the specified MDC property to the event. Access to the MDC is not synchronized, so this method should only be called when it is known that no other threads are accessing the MDC.
    
    Parameters:
    
    propName -
    
    propValue -
    
    Since:
    
    1.2.15
  - getProperty
```
public final String getProperty(String key)
```
    Return a property for this event. The return value can be null.
    Equivalent to getMDC(String) in log4j 1.2. Provided for compatibility with log4j 1.3.
    
    Parameters:
    
    key - property name
    
    Returns:
    
    property value or null if property not set

    true if location information has been extracted.
    
    Since:
    
    1.2.15
  - getTimeStamp

    Getter for the event's time stamp. The time stamp is calculated starting from 1970-01-01 GMT.
    
    Returns:
    
    timestamp
    
    Since:
    
    1.2.15
  - getPropertyKeySet
```
public Set getPropertyKeySet()
```
    Returns the set of the key values in the properties for the event.
    The returned set is unmodifiable by the caller.
    Provided for compatibility with log4j 1.3
    
    Returns:
    
    Set an unmodifiable set of the property keys.
    
    Since:

```
    Get the fully qualified name of the calling logger sub-class/wrapper. Provided for compatibility with log4j 1.3
    
    Returns:
    
    fully qualified class name, may be null.
