Method Detail

getContentType

public final String getContentType()

Description copied from interface: HttpParser

Returns the content type.

Specified by:

getContentType in interface HttpParser

parse

public <T> T parse(HttpResponse response,
                   Class<T> dataClass)
        throws IOException

Description copied from interface: HttpParser

Parses the given HTTP response into a new instance of the the given data class of key/value pairs.

How the parsing is performed is not restricted by this interface, and is instead defined by the concrete implementation. Implementations should check HttpResponse.isSuccessStatusCode() to know whether they are parsing a success or error response.

Specified by:

parse in interface HttpParser

Throws:

IOException

parse

public static void parse(String content,
                         Object data)

Parses the given URL-encoded content into the given data object of data key name/value pairs, including support for repeating data key names.

Declared fields of a "primitive" type (as defined by Data.isPrimitive(Type) are parsed using Data.parsePrimitiveValue(Type, String) where the Class parameter is the declared field class. Declared fields of type Collection are used to support repeating data key names, so each member of the collection is an additional data key value. They are parsed the same as "primitive" fields, except that the generic type parameter of the collection is used as the Class parameter.

If there is no declared field for an input parameter name, it will be ignored unless the input data parameter is a Map. If it is a map, the parameter value will be stored either as a string, or as a ArrayList<String> in the case of repeated parameters.

Parameters:

content - URL-encoded content or null to ignore content

data - data key name/value pairs

builder

public static UrlEncodedParser.Builder builder()

Returns an instance of a new builder.
