• toString

  public static String toString(ToXContent toXContent)

  Writes serialized toXContent to pretty-printed JSON string.

  Parameters:

  toXContent - object to be pretty printed

  Returns:

  pretty-printed JSON serialization

• toString

  public static String toString(ToXContent toXContent,
                                ToXContent.Params params)

  Writes serialized toXContent to pretty-printed JSON string.

  Parameters:

  toXContent - object to be pretty printed

  params - serialization parameters

  Returns:

  pretty-printed JSON serialization

• update

  public static boolean update(Map<String,Object> source,
                               Map<String,Object> changes,
                               boolean checkUpdatesAreUnequal)

  Updates the provided changes into the source. If the key exists in the changes, it overrides the one in source unless both are Maps, in which case it recuersively updated it.

  Parameters:

  source - the original map to be updated

  changes - the changes to update into updated

  checkUpdatesAreUnequal - should this method check if updates to the same key (that are not both maps) are unequal? This is just a .equals check on the objects, but that can take some time on long strings.

  Returns:

  true if the source map was modified

• mergeDefaults

  public static void mergeDefaults(Map<String,Object> content,
                                   Map<String,Object> defaults)

  Merges the defaults provided as the second parameter into the content of the first. Only does recursive merge for inner maps.

• copyCurrentStructure

  public static void copyCurrentStructure(XContentGenerator generator,
                                          XContentParser parser)

                            throws IOException

  Writes a "raw" (bytes) field, handling cases where the bytes are compressed, and tries to optimize writing using XContentBuilder.rawField(String, org.elasticsearch.common.bytes.BytesReference).

  Throws:

  IOException
