public class DagWood

extends Abraham

Each dagwood defines a partial ordering of TracePositions. Several implementation
variables use longs because they represent the size of an in-core array (which can''t get
that large). The variable ''myRoot'' is just for debugging for the moment.

Constructor Detail

DagWood

public DagWood()

DagWood

public DagWood(Rcvr receiver)

Method Detail

root

public TracePosition root()

successorBranchOfPosition

public BranchDescription successorBranchOfPosition(BranchDescription branch,
                                                   int position)

Return all the successors of the receiver in the trace tree.

successorsOf

public MuSet successorsOf(TracePosition trace)

Return the first used positions on all the successors of trace.

installBranchAfter

public void installBranchAfter(BranchDescription branch,
                               TracePosition anchorTrace)

Lookup the anchorTrace to find the branch hanging off it. If there isn't one,
then install branch as that branch. Otherwise walk a balanced walk down the
binary tree of branches to find a place to hang the new branch.

newPosition

public TracePosition newPosition()

This should really create a new root, but that's harder to draw!!.

cacheTracePos

public PrimIndexTable cacheTracePos(TracePosition tracePos)

Install the supplied branch and position as the navCache and return it.

inspect

public void inspect()

Overrides:

inspect in class AboraHeaper

restartDagWood

public void restartDagWood(Rcvr trans)

re-initialize the non-persistent part

contentsHash

public int contentsHash()

Description copied from class: Abraham

A hash of the contents of this flock

Overrides:

contentsHash in class Abraham

sendSelfTo

public void sendSelfTo(Xmtr xmtr)

Description copied from class: Heaper

do nothing

Overrides:

sendSelfTo in class Abraham
