ExchangeRateParser

public class ExchangeRateParser extends Parser<ExchangeRateResponse>

Turns a decoded CURRENCY_EXCHANGE_RATE payload into an ExchangeRateResponse.

The quote sits under the payload's single top-level key, which the parser reaches for by position rather than by name. An error payload carries a plain message string at that position instead of a nested object, so the failed cast is itself the signal to read the value as an error message.

Constructors

ExchangeRateResponse.ExchangeRateParser

public void ExchangeRateResponse.ExchangeRateParser()

Functions

getNumberFromString

public static N getNumberFromString<N extends Number>(String s, Function<String, N> parser)

onParseError

public ExchangeRateResponse onParseError(String error)

Wraps a parse failure or an API error message in a response.

parse

public ExchangeRateResponse parse(Map<String, Object> stringObjectMap)

Reads the quote fields into a response.

parseJSON

public static Map<String, Object> parseJSON(String responseBody)

Decodes a raw JSON response body into a generic String-keyed map, with the NoneableDouble/NoneableLong adapters registered so numeric-or-"None" fields decode correctly.

public static U parseJSON(String responseBody, Class c)

Decodes a raw JSON response body directly into an instance of c, with the NoneableDouble/NoneableLong adapters registered so numeric-or-"None" fields decode correctly.

parseJSONList

public static List parseJSONList(Object object, Class klass)

Converts an already-decoded JSON value, typically a List produced by parseJSON, into a List of klass instances, with the NoneableDouble/NoneableLong adapters registered so numeric-or-"None" fields decode correctly.

toJSON

public static String toJSON(Map<String, Object> data)

Encodes a String-keyed map back into a JSON string, with the NoneableDouble/NoneableLong adapters registered.
