From source file:google.registry.config.YamlUtils.java

/**
 * Recursively merges two YAML documents together.
 *
 * <p>Any fields that are specified in customYaml will override fields of the same path in
 * defaultYaml. Additional fields in customYaml that aren't specified in defaultYaml will be
 * ignored. The schemas of all fields that are present must be identical, e.g. it is an error to
 * override a field that has a Map value in the default YAML with a field of any other type in the
 * custom YAML./*from w  w w. j  a v a  2s  .  c  o  m*/
 *
 * <p>Only maps are handled recursively; lists are simply overridden in place as-is, as are maps
 * whose name is suffixed with "Map" -- this allows entire maps to be overridden, rather than
 * merged.
