java.lang.Object
  org.planx.xmlstore.references.ValueReference

All Implemented Interfaces:

Serializable, Comparable<ValueReference>, Reference

public class ValueReference
extends Object
implements Reference, Serializable, Comparable<ValueReference>

A unique location independent Reference computed from a content hash of a Node (currently MD5). Use reference(Node) to create a ValueReference.

Method Detail

reference

public static ValueReference reference(Node n)

Creates a ValueReference by computing a content hash of the tree rooted at the specified node. If the node already has a ValueReference set (by some internal means) this ValueReference will be returned instead of computing a new one.

asIdentifier

public Identifier asIdentifier()

equals

public boolean equals(Object o)

Returns true if and only if the specified object is also a ValueReference and it represents the same content hash as this ValueReference.

Overrides:

equals in class Object

compareTo

public int compareTo(ValueReference vref)

Specified by:

compareTo in interface Comparable<ValueReference>

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object

getStreamer

public static SizeStreamer<ValueReference> getStreamer()

getDiscriminator

public static org.planx.msd.Discriminator<ValueReference> getDiscriminator()

getDiscriminator
