Class NamedConverter

All Implemented Interfaces:
ContextAware, LifeCycle
Direct Known Subclasses:
ClassOfCallerConverter, LoggerConverter

public abstract class NamedConverter extends ClassicConverter
In case abbreviation service is requested, NamedConverter will convert fully qualified class names to their abbreviated from. NamedConverter instances will store abbreviated names in an internal LRU cache. The cache will double in size if he cache miss rate is consistently above 30%. Assuming a high miss rate, the doubling until a maximum size of 2048 is attained. If at this point the cache miss rate is still too high, NamedConverter will revert to non cached behavior. The general assumption here is that a large majority of logger names are concentrated within a group of approximately 1000 logger names.

      Description copied from class: DynamicConverter
      Components that depend on options passed during configuration can override this method in order to make appropriate use of those options. For simpler components, the trivial implementation found in this abstract class will be sufficient.

    • convert

      public String convert(ILoggingEvent event)
      Description copied from class: Converter
      The convert method is responsible for extracting data from the event and storing it for later use by the write method.
