NetworkTracer

public NetworkTracer(TraceNodeW.Table _traceNodeTable,
             TrustEdge.Table _trustEdgeTable)

Constructs a NetworkTracer.

Method Detail

extendLevelChange

public void extendLevelChange(TraceNodeW node0,
                     int old0Level)
                       throws SQLException

Extends a change in trust level from the specified node. Does nothing if no change actually occured (current level equals old0Level). Otherwise, recursively extends the change into the network. For this to work, the node table must already contain a node for each registered voter. Furthermore, each trust edge that is barred must already be marked as barred.

Parameters:

node0 - a source node

old0Level - its trust level prior to the change

Throws:

SQLException

traceNodeTable

public TraceNodeW.Table traceNodeTable()

The trace-node table for the trace.

trustEdgeTable

TrustEdge.Table trustEdgeTable()

The trust-edge table for the trace.
