Class ContextDataFactory


public class ContextDataFactory extends Object
Factory for creating the StringMap instances used to initialize LogEvents' context data. When context data is injected into the log event, these StringMap instances may be either populated with key-value pairs from the context, or completely replaced altogether.

By default returns SortedArrayStringMap objects. Can be configured by setting system property "log4j2.ContextData" to the fully qualified class name of a class implementing the StringMap interface. The class must have a public default constructor, and if possible should also have a public constructor that takes a single int argument for the initial capacity.
