RestClient (Gluon Mobile 4.4.0-jdk9 API)

java.lang.Object
- com.gluonhq.connect.provider.RestClient

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)
```
    Creates an instance of 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.
    
    Type Parameters:
    
    T - the type of the object to read
    
    Parameters:
    
    targetClass - the class definition of the object to read
    
    Returns:
    
    an ObjectDataReader instance that constructs an object from an HTTP connection with an automatically detected converter
  - createObjectDataReader
```
public <T> ObjectDataReader<T> createObjectDataReader(InputStreamInputConverter<T> converter)
```
    Creates an instance of 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 and convert it into an object by using the specified converter.
    
    Type Parameters:
    
    T - the type of the object to read
    
    Parameters:
    
    converter - the converter to use to convert the data read from the HTTP connection into an object

    an ObjectDataReader instance that constructs an object from an HTTP connection with the specified converter
  - createObjectDataWriter
```
public <T> ObjectDataWriter<T> createObjectDataWriter(java.lang.Class<T> targetClass)
```
    Creates an instance of 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.
    
    Type Parameters:
    
    T - the type of the object to write
    
    Parameters:
    
    targetClass - the class definition of the object to write
    
    Returns:
    
    an ObjectDataWriter instance that writes an object into an HTTP connection with an automatically detected output converter and that constructs an object from that HTTP connection with an automatically detected input converter
  - createObjectDataWriter
```
public <T> ObjectDataWriter<T> createObjectDataWriter(OutputStreamOutputConverter<T> outputConverter,
                                                      InputStreamInputConverter<T> inputConverter)
```
    Creates an instance of ObjectDataWriter that can be passed directly in the DataProvider.storeObject(Object, ObjectDataWriter) method. The object data writer will convert an object by using the specified output 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 use the specified input converter to convert the read bytes from the response of the HTTP request into an object.
    
    Type Parameters:
