Method Detail

fromDoubles

public static long fromDoubles(double lowDouble,
               double highDouble)

Return a long from a pair of doubles { low, high } such that the actual value is equal to high + low.

prepareToRead

public void prepareToRead(String encoded)
                   throws SerializationException

Prepare to read the stream.

Parameters:

encoded - unused true if the stream is encoded

Throws:

SerializationException

readObject

public final Object readObject()
                        throws SerializationException

Specified by:

readObject in interface SerializationStreamReader

Throws:

SerializationException

deserialize

protected abstract Object deserialize(String typeSignature)
                               throws SerializationException

Deserialize an object with the given type signature.

Parameters:

typeSignature - the type signature to deserialize

Returns:

the deserialized object

Throws:

SerializationException

getDecodedObject

protected final Object getDecodedObject(int index)

Get the previously seen object at the given index which must be 1-based.

Parameters:

index - a 1-based index into the seen objects

Returns:

the object stored in the seen array at index - 1
