public class RestClient
extends java.lang.Object
The RestClient assists in using the DataProvider
with HTTP URLs as the data source. For instance, to read
an object from a sample URL that responds with json, you can use the following code:
RestClient restClient = RestClient.create() .host("http://myhost.com") .path("restservice/2/sample/19") .method("GET"); GluonObservableObject<Sample> sample = DataProvider.retrieveObject(restClient.createObjectDataReader(Sample.class));

public <T> ObjectDataReader<T> createObjectDataReader(java.lang.Class<T> targetClass)
ObjectDataReader
that can be passed directly in the
DataProvider.retrieveObject(ObjectDataReader)
method. The object data reader will read the data from
the HTTP connection provided by the RestDataSource.
The object data reader will try to detect the converter to use based on the Content-Type response header that
is returned from the HTTP connection. The specified targetClass
will be passed in to the detected
converter where needed. A custom converter can be specified with createObjectDataReader(InputStreamInputConverter)
when no suitable converter could be detected.

ObjectDataWriter
that can be passed directly in the
DataProvider.storeObject(Object, ObjectDataWriter)
method.
The object data writer will try to detect the output converter to use based on the Content-Type
request header that was set. The specified targetClass
will be passed in to the detected converter
where needed. A custom output converter can be specified with createObjectDataWriter(OutputStreamOutputConverter, InputStreamInputConverter)
when no suitable converter could be detected. If an output converter could be found, the writer will convert an
object by using the detected converter and writes the converted data to the OutputStream of the HTTP connection
that is provided by the RestDataSource.
The ObjectDataWriter also returns an optional object. In case of the RestClient, the returned object will be
read from the response of the HTTP request. The object data reader will try to detect the input converter to use
based on the Content-Type response header that is returned from the HTTP connection. The specified
targetClass
will be passed in to the detected input converter as well where needed. The reader will
then use the input converter to convert the read bytes from the response of the HTTP request into an object.
