get
public static MetadataHandler.Builder<MetadataKey.KeyValueHandler> getDefaultBuilder(Set<MetadataKey<? extends Object>> ignored)
Returns a new MetadataHandler.Builder which handles all non-ignored metadata keys by dispatching their values to the key itself. This is convenient for generic metadata processing when used in conjunction with something like KeyValueFormatter.
The returned builder can be built immediately or customized further to handler some keys specially (e.g. allowing keys/values to modify logging behaviour).
Return
a builder configured with the default key/value handlers and ignored keys.
