Class MessageFormatCache

java.lang.Object

net.logstash.logback.marker.MessageFormatCache

public class MessageFormatCache
extends Object

A cache for MessageFormat objects.

Since only a small subset of MessageFormats are generally used by SingleFieldAppendingMarker, the MessageFormatCache will cache them (per thread) so that they can be reused.

This is a performance optimization to save MessageFormat construction and parsing time for each argument/marker.
