SimpleParser

public abstract class SimpleParser<T, U> extends Parser<T>

A Parser counterpart to DefaultParser for subclasses that parse a pre-shaped input of type U directly, rather than receiving the metadata-plus-time-series split DefaultParser performs.

parse is not implemented here: it always returns null, since this class' parsing entry point is parse(U).

Parameters

<T>

the response type produced by this parser

the pre-shaped input type this parser consumes

Constructors

SimpleParser

public void SimpleParser()

Functions

getNumberFromString

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

onParseError

public abstract T onParseError(String error)

Produces the value this parser returns in place of a response object when the reply cannot be parsed, for example an empty or unrecognizable JSON body.

parse

public abstract T parse(U data)

Parses a pre-shaped input into a response object.

public final T parse(Map<String, Object> object)

Always returns null.

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.
