Method Detail

writeContent

public final void writeContent(JsonWriter out)
                        throws IOException

Writes a JSON object containing keys for all fields of this object.

In contrast to DataObject.writeTo(JsonWriter), the resulting object contains no type information. Therefore, this method must only be called directly, if the reader knows the type of the object to read from the context. For reading the data, a per-type generated read[type-name]() method must be called.

Parameters:

out - The writer to write to.

Throws:

IOException

writeFields

protected void writeFields(JsonWriter out)
                    throws IOException

Writes all fields of this instance to the given output.

Parameters:

out - The writer to write to.

Throws:

IOException - If writing fails.

readFields

protected final void readFields(JsonReader in)
                         throws IOException

Reads all fields of this instance from the given input.

Parameters:

in - The reader to take the input from.

Throws:

IOException

readField

protected void readField(JsonReader in,
                         String field)
                  throws IOException

Reads the given field from the given input.

Parameters:

in - The reader to take the value from.
