Method Detail

getJsonReader

public JsonReader<T> getJsonReader()

Returns:

the JsonReader for converting the JSON to an instance of T.

getModel

public T getModel()
           throws IOException

Converts the JSON to an instance of T using the JsonReader given as constructor argument. Returns null if JsonRepresentation.getJsonObject() or JsonReader is null.

Specified by:

getModel in interface PiritiRepresentation<T>

Returns:

the converted instance of T or null if JsonRepresentation.getJsonObject() or JsonReader is null.

Throws:

IOException

getModels

public List<T> getModels()
                  throws IOException

Converts the JSON to a list of Ts using the JsonReader given as constructor argument. Returns null if JsonRepresentation.getJsonObject() or JsonReader is null. More precisely the JSON has to be a JSON object with one key (name does not matter). The value of this key has to be a JSON array which is converted to instances of T.

Specified by:
