Constructor Summary

AvlTreeMarshaller(java.util.Comparator<E> comparator)
Creates a new instance of AvlTreeMarshaller with the default key Marshaller which uses Java Serialization.

AvlTreeMarshaller(java.util.Comparator<E> comparator, Marshaller<E> keyMarshaller)
Creates a new instance of AvlTreeMarshaller with a custom key Marshaller.

Method Summary

AvlTree<E>	deserialize(byte[] data) Creates an AVLTree from given bytes of data.
LinkedAvlNode<E>	readTree(java.io.DataInputStream in, LinkedAvlNode<E> node, LinkedAvlNode[] nodes) Reads the data from given InputStream and creates the LinkedAvlNodes to form the tree node = [size] [data-length] [data] [index] [child-marker] [node] [child-marker] [node].
byte[]	serialize(AvlTree<E> tree) Marshals the given tree to bytes

public AvlTreeMarshaller(java.util.Comparator<E> comparator,
                         Marshaller<E> keyMarshaller)

Creates a new instance of AvlTreeMarshaller with a custom key Marshaller.

Parameters:

comparator - Comparator to be used for key comparision

keyMarshaller - marshaller for keys

AvlTreeMarshaller

public AvlTreeMarshaller(java.util.Comparator<E> comparator)

Creates a new instance of AvlTreeMarshaller with the default key Marshaller which uses Java Serialization.

Parameters:

comparator - Comparator to be used for key comparision

Method Detail

serialize

public byte[] serialize(AvlTree<E> tree)

Marshals the given tree to bytes

Specified by:

serialize in interface Marshaller<AvlTree<E>>

Parameters:

tree - the tree to be marshalled

deserialize

public AvlTree<E> deserialize(byte[] data)
                       throws java.io.IOException

Creates an AVLTree from given bytes of data.

Specified by:

deserialize in interface Marshaller<AvlTree<E>>

Parameters:

data - byte array to be converted into AVLTree

Throws:

java.io.IOException

readTree

public LinkedAvlNode<E> readTree(java.io.DataInputStream in,
                                 LinkedAvlNode<E> node,
                                 LinkedAvlNode[] nodes)
                          throws java.io.IOException

Reads the data from given InputStream and creates the LinkedAvlNodes to form the tree node = [size] [data-length] [data] [index] [child-marker] [node] [child-marker] [node].

Parameters:

in - the input stream to deserialize from

node - the node to deserialize

Returns:

the deserialized AvlTree node

Throws:

java.io.IOException - on failures to deserialize or read from the stream
