Method Detail

newGluonObservableObject

public GluonObservableObject<T> newGluonObservableObject()

Description copied from interface: ObjectDataReader

Provide an instance of a GluonObservableObject. This method is called by DataProvider.retrieveObject(ObjectDataReader) to get a GluonObservableObject that will contain the actual object when the retrieve operation has completed successfully. Most implementations will just return an instance of GluonObservableObject itself. Note that it is perfectly valid to return existing instances of GluonObservableObject.

Specified by:

newGluonObservableObject in interface ObjectDataReader<T>

Returns:

an instance of a GluonObservableObject

createRestDataSource

protected RestDataSource createRestDataSource()
                                       throws IOException

Throws:

IOException

readObject

public T readObject()
             throws IOException

Description copied from interface: ObjectDataReader

Reads the object and returns it. The actual source of the read and the method that converts the read data into an object instance is completely left to the implementation. This method is called by DataProvider.retrieveObject(ObjectDataReader) to initiate the actual read process. The returned object will be set on the GluonObservableObject that is returned in the ObjectDataReader.newGluonObservableObject() method.

Specified by:

readObject in interface ObjectDataReader<T>

Returns:

the read object

Throws:

IOException - when an exception occurred during the read process

unmarshallObject

protected T unmarshallObject(javax.json.JsonObject jsonObject)
                      throws IOException

Throws:

IOException

readJsonObject

protected javax.json.JsonObject readJsonObject(IODataSource dataSource)
                                        throws IOException

Throws:

IOException
