Method Details

serialize

public static void serialize(XContentBuilder builder,
 @Nullable
 ExponentialHistogram histogram)
                      throws IOException

Serializes an ExponentialHistogram to the provided XContentBuilder.

Parameters:

builder - the XContentBuilder to write to

histogram - the ExponentialHistogram to serialize

Throws:

IOException - if the XContentBuilder throws an IOException

parseForTesting

public static ExponentialHistogram parseForTesting(XContentParser xContent)
                                            throws IOException

Parses an ExponentialHistogram from the provided XContentParser. This method is neither optimized, nor does it do any validation of the parsed content. No estimation for missing sum/min/max is done. Therefore only intended for testing!

Parameters:

xContent - the serialized histogram to read

Returns:

the deserialized histogram

Throws:

IOException - if the XContentParser throws an IOException

parseForTesting

public static ExponentialHistogram parseForTesting(@Nullable
 Map<String,Object> xContent)

Parses an ExponentialHistogram from a Map. This method is neither optimized, nor does it do any validation of the parsed content. No estimation for missing sum/min/max is done. Therefore only intended for testing!

Parameters:

xContent - the serialized histogram as a map

Returns:

the deserialized histogram
