Field Detail

nodeIdBitLength

public static final int nodeIdBitLength

This is the bit length of the node ids. If it is n, then there are 2^n different Pastry nodes. We currently assume that it is divisible by 32.

Method Detail

buildNodeId

public static NodeId buildNodeId(int[] material)

Constructor.

Parameters:

material - an array of length at least IdBitLength/32 containing raw Id material.

buildNodeId

public static NodeId buildNodeId(byte[] material)

Constructor.

Parameters:

material - an array of length at least IdBitLength/8 containing raw Id material.

buildNodeId

public static NodeId buildNodeId()

Constructor. It constructs a new Id with a value of 0 for all bits.
