Class Locator.CompactStreamer

java.lang.Object
  org.planx.io.Locator.CompactStreamer

All Implemented Interfaces:

SizeStreamer<Locator>, Streamer<Locator>

Enclosing class:

Locator

public static class Locator.CompactStreamer
extends Object
implements SizeStreamer<Locator>

A Streamer capable of converting a Locator to and from byte representation. The streamer can also write locators in a compact manner for a specific SourceId. That is, by calling setCompactId(SourceId) an id can be set such that all locators with this SourceId will not have their ids written in the byte representation (all others will). Thus, these locators are written in a very compact way. However, in order to be able to read them back-in the original SourceId must of course be known.

Constructor Summary

Locator.CompactStreamer()

Locator.CompactStreamer(SourceId id)

Method Summary

Locator	fromStream(DataInput in) Reads an object of class E from the data source.
SourceId	getCompactId()
void	setCompactId(SourceId id)
long	size(Locator l) Returns the number of bytes that this Streamer will write when the toStream method is invoked on the specified object.
void	toStream(DataOutput out, Locator l) Writes the internal state of the object to the data source in a format that can later be read by the same Streamer using the fromStream method.
