Description

Class Summary
BridgePatternConverter | The class implements the pre log4j 1.3 org.apache.log4j.helpers.PatternConverter contract by delegating to the log4j 1.3 pattern implementation.
BridgePatternParser | The class implements the pre log4j 1.3 org.apache.log4j.helpers.PatternConverter contract by delegating to the log4j 1.3 pattern implementation.
CachedDateFormat | CachedDateFormat optimizes the performance of a wrapped DateFormat.
ClassNamePatternConverter | Formats the class name of the site of the logging request.
DatePatternConverter | Convert and format the event's date in a StringBuffer.
FileDatePatternConverter | Formats an date by delegating to DatePatternConverter.
FileLocationPatternConverter | Return the event's line location information in a StringBuffer.
FormattingInfo | Modifies the output of a pattern converter for a specified minimum and maximum width and alignment.
FullLocationPatternConverter | Format the event's line location information.
IntegerPatternConverter | Formats an integer.
LevelPatternConverter | Return the event's level in a StringBuffer.
LineLocationPatternConverter | Return the event's line location information in a StringBuffer.
LineSeparatorPatternConverter | Formats a line separator.
LiteralPatternConverter | Formats a string literal.
LogEvent | 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.
LoggerPatternConverter | Formats a logger name.
LoggingEventPatternConverter | LoggingEventPatternConverter is a base class for pattern converters that can format information from instances of LoggingEvent.
MessagePatternConverter | Return the event's rendered message in a StringBuffer.
MethodLocationPatternConverter | Return the event's line location information in a StringBuffer.
NameAbbreviator | NameAbbreviator generates abbreviated logger and class names.
NamePatternConverter | Base class for other pattern converters which can return only parts of their name.
NDCPatternConverter | Return the event's NDC in a StringBuffer.
PatternConverter | PatternConverter is an abstract class that provides the formatting functionality that derived classes need.
PatternParser | Most of the work of the `EnhancedPatternLayout` class is delegated to the PatternParser class.
PropertiesPatternConverter | Able to handle the contents of the LoggingEvent's Property bundle and either output the entire contents of the properties in a similar format to the java.util.Hashtable.toString(), or to output the value of a specific key within the property bundle when this pattern converter has the option set.
RelativeTimePatternConverter | Return the relative time in milliseconds since loading of the LoggingEvent class.
SequenceNumberPatternConverter | Formats the event sequence number.
ThreadPatternConverter | Formats the event thread name.
ThrowableInformationPatternConverter | Outputs the ThrowableInformation portion of the LoggingEvent.
