  org.planx.xmlstore.routing.TimestampedValue

All Implemented Interfaces:

Serializable, Streamable

public class TimestampedValue
extends Object
implements Streamable, Serializable

A wrapper class that adds a timestamp to any serializable object. The object is internally represented by a byte array and can both be returned as a byte array and as an object.

Method Summary

void	fromStream(DataInput in) Reads the internal state of the Streamable object from the input stream.
byte[]	getByteArray() Returns the value as a byte array.
Serializable	getObject() Returns the value as an Object.
long	timestamp()
void	toStream(DataOutput out) Writes the internal state of the Streamable object to the output stream in a format that can later be read by the same Streamble class using the Streamable.fromStream(java.io.DataInput) method.
String	toString()

                 throws IOException

Throws:

IOException

                 throws IOException

Throws:

IOException

Method Detail

fromStream

public void fromStream(DataInput in)
                throws IOException

Description copied from interface: Streamable

Reads the internal state of the Streamable object from the input stream. Immutable objects should throw an UnsupportedOperationException, and instead implement a constructor as described above.

Specified by:

fromStream in interface Streamable

Throws:

IOException

toStream

public void toStream(DataOutput out)
              throws IOException

Description copied from interface: Streamable

Writes the internal state of the Streamable object to the output stream in a format that can later be read by the same Streamble class using the Streamable.fromStream(java.io.DataInput) method.

Specified by:

toStream in interface Streamable

Throws:

IOException

timestamp

public long timestamp()

getByteArray

public byte[] getByteArray()

Returns the value as a byte array.

getObject

public Serializable getObject()
                       throws IOException

Returns the value as an Object.

Throws:

IOException

toString

public String toString()

Overrides:

toString in class Object
