Method Detail

getCounts

public void getCounts(int[] nCounts,
                      int[] nNodes,
                      int[] nOffsets,
                      int iNode,
                      int iOffset,
                      ADNode parent,
                      boolean bSubstract)

get counts for specific instantiation of a set of nodes

Parameters:

nCounts - array for storing counts

nNodes - array of node indexes

nOffsets - offset for nodes in nNodes in nCounts

iNode - index into nNode indicating current node

iOffset - Offset into nCounts due to nodes below iNode

parent - parant ADNode of this VaryNode

bSubstract - indicate whether counts should be added or substracted

print

public void print(String sTab)

print is used for debugging only, called from ADNode

Parameters:

sTab - amount of space.

getRevision

public String getRevision()

Returns the revision string.

Specified by:

getRevision in interface RevisionHandler

Returns:

the revision
